Same Owner from New:1975 Yamaha TA125 for Sale

 

1975 Yamaha TA125 L Side

The TA125 was Yamaha’s over-the-counter production roadracer built between 1971 and 1975. Prior to the TA, racers who rode Yamahas bought stock YAS1 or AS2’s and converted them to track specification using GYT factory race kits that included a comprehensive package of go-fast bits. But the finished bikes were ultimately limited by frames and suspension geometry designed for road use, and performance was not on par with class leaders.

1975 Yamaha TA125 Dash

The TA that followed wasn’t really a full racing bike like its bigger 250 and 350cc siblings, and was really a half-hearted effort: many parts were shared with the roadgoing AS3, making it a sort of “factory racing AS3” than a pure race bike, although this did make maintaining the TA125 a much less expensive proposition and the bikes were popular with privateers.

This particular example is currently being offered for sale by the same family that has owned it from new. Like most bikes that have seen serious race track use, it’s not dead stock, having been upgraded during its racing career to remain competitive, although the upgrades are obviously period appropriate and designed to enhance racetrack performance.

From the original eBay listing: 1975 Yamaha TA125 for Sale

This motorcycle was one of two bought new by my father in 1977 from Twin-K Yamaha in Detroit Michigan. They were shipped to Venezuela where we lived. My brother raced it in the 1978 Venezuelan Grand Prix of the FIM World Championship qualifying 19th (first TA). I later rode it in AHRMA in the United States. I rebuilt/restored the bike about 10 years ago, rebuilt crank (new rods and bearings), new cases, pistons, rings, seals and rolled it into my dining room. It has a Fontana 4-leading shoe drum brake as was raced in the GP. The rims are not original, most everyone went with wider WM-3 rims to take advantage of the new Dunlops. It also has a box section swingarm and Koni shocks. I can’t remember who made the swingarm. The bike needs some odds and ends. Front brake lever and perch, plug cap, rear brake cable spring, shift link rod. Frame # 400-990258. When I did the motor I used a NOS set of cases I had. The matching number engine cases #AS3-990258, original front brake, and standard shocks will be provided. I have some fairings laying around.

Interestingly, with just under two days left on the auction and a starting bid of $10,000 there are no nibbles as yet. While it may not have had a famous rider, it’s pretty cool that the entire history of the bike is known, and the guy selling it is the guy who raced it. But perhaps the price is a bit too rich? Or maybe they’re picking up on a “maybe I don’t really want to sell this bike” vibe from the seller? I know that it’d be hard to part with something like this if I’d put blood and sweat into competing on it…

Regardless, make an offer and maybe he’ll bite: this one is ready for display, or set it up for vintage racing.

Tasty Two-Stroke: 1985 Yamaha RZ350 for Sale

1985 Yamaha RZ350 L Side Front

I’ve only recently become an acolyte in the Church of Smokers. Growing up, I mostly heard them in the context of dirt bikes ripping up and down our street, and the angry, mechanical-insect noise isn’t really the sexiest… But I’ve opened my mind to the antisocial little things, and this bike might make a great introduction to two-stroke ownership.

Sold between 1984 and 1985 in the US, the Yamaha RZ350 was powered by a liquid-cooled, two-stroke parallel-twin that displaced 347cc’s. This long-serving powerplant was introduced in 1983, with variants finding home in select Yamahas until 2006.

1985 Yamaha RZ350 R Front

Evolved from the RD350, the RZ added liquid-cooling and Yamaha’s torque-enhancing power-valve technology dubbed, originally enough, “YPVS.” Can you guess what that stands for? This computer-controlled system helped to smooth out the traditionally peaky power delivery of the two-stroke, plumping the mid-range for improved street usability.

1985 Yamaha RZ350 Dash

A terror on back roads of the time, the RZ350 was literally one of the best-handling bikes you could buy at any price. Remember, this was before the GSX-R750 was introduced, and while many bikes made more power, they were usually correspondingly heavy and unwieldy: the RZ was light and nimble, with a powerband that needed chasing and a gearbox that rewarded the rider for doing so, a real enthusiast’s motorcycle.

1985 Yamaha RZ350 L Front

The RZ is the epitome of a “useable classic:” these are fun to ride, with plenty of power. They’re striking to look at with a strong community of experts and amateurs to help you keep your little bumblebee buzzing. Parts availability is excellent and  includes a wide range of updated parts, owing to the long production run of these two-strokes into the modern era, with many parts easily retrofitted to improve reliability and performance.

Pristine Vintage Racer: 1967 Yamaha TD1-C for Sale

1967 Yamaha TD-1C L Front

Yamaha introduced their TD1 race bike in 1962 as an over-the-counter ride for professional race teams and privateers. The machine went through several updates before the TD2 was introduced in 1969, and this “C” model from 1967 was the final version of the bike.

1967 Yamaha TD-1C R Rear

Race bikes generally epitomize The Ten Foot Rule when it comes to aesthetics: if it looks good from ten feet away, it’s good enough. Especially when you’re dealing with grassroots or privateer efforts: when you ride hard, you’re going to crash, so the last place you want to spend your resources is on a paint job, since that’s going to be obliterated the first time you lowside… But this one bucks that trend, and is restored to what appears to be a very high standard.

1967 Yamaha TD-1C R Front

Rarity and value aside, there are owners who remorselessly flog their valuable vintage cars and bikes on racetracks. And while part of me recoils in horror at the thought of some weekend-warrior with more money than skill stuffing their nearly irreplaceable machines into a wall or hay bale, another part of me is immeasurably grateful that I’m able to see and hear these classics being used as they were intended.

1967 Yamaha TD-1C Dash

While this one has not been actively raced since being restored, the seller is clearly extremely knowledgeable and the original listing features a very comprehensive list of the work that’s been done to this one and a well-written history of the bike and its owners/riders, so pop over for a look.

1967 Yamaha TD-1C Engine

From the original listing: 1967 Yamaha TD1-C for Sale

This Investment Quality 4th Generation TD1-C Rebuild incorporated as many ‘original to the bike’ parts as practicality and availability allowed. The crank is fresh and true, the excellent condition cylinders have good original chrome, and the proper “C” windowed pistons have new rings, pins, and small end bearings. The transmission, H/D clutch, and straight-cut primary drive are all correct Daytona bits in excellent condition – the close ratio gearbox has been shimmed and adjusted.

The original ‘black wire’ M200 Magneto was cleaned, serviced and adjusted. The 27mm Amal/Mikuni smooth-bore carburetors and remote floats were also dismantled, cleaned and inspected; the float isolator is sound. The kick-start mechanism had already been removed (a very common practice of the time), and the clutch cover had been trimmed to save weight. The paint and finish on all but the mag cover is factory original.

The matching numbers cases are free of any damage or welds; no engine failures appear to have ever occurred inside or out. All rubber seals and engine gaskets have been renewed. The frame, swing arm, fork legs, and fairing brackets were stripped, carefully inspected for cracks or damage, and received a quality repaint; original early Yamaha racer paint is generally poor, and this one definitely needed a do over.

The wheels were taken down, hubs serviced, rims and spokes polished then restrung and trued, with period correct race tires installed. Most sundries excluding the grips and pegs are original to the bike and polished up well; cables, pivots, shafts and contact surfaces were all cleaned and lubricated. The forks have been rebuilt with modern seals. The bike has been assembled and safety wired in fine race tradition.

The original seat cover still looks great, with no splits or tears. Every part of the bike has been detailed, refinished, polished or replaced.

The fairing was missing – a new unpainted AirTech TD1 Replica is installed. Note: due to Import Laws of the time, fiberglass fairings were not allowed on incoming U.S. market bikes – the TD1 would have originally been sold without a fairing.

1967 Yamaha TD-1C Rear Suspension

The asymmetrical paint scheme is particularly striking, with some of the original period red paint and lettering on one side and fresh white paint on the other. And, on the mechanical side, the build features a heavy-duty clutch as an upgrade to the notoriously fragile unit Yamaha originally fitted.

1967 Yamaha TD-1C L Rear

While the bike is probably more suited to display, due to increasing rarity and the amount of money that’s gone into the restoration, it’s also been built to “do the business” and should just require gas and fresh tires before hitting the track. The seller mentions that the engine has been “well-lubricated internally for long-term display”, so all the moving parts should still be ready to move, not seized-up into a very evocative, vintage-styled paperweight…

Complete Package: 1973 Yamaha RD350 Cafe

1973 Yamaha RD350 R Front

Another really nice little Yamaha RD350 with some subtle custom touches that can be easily reversed if a potential buyer would prefer something a bit more stock… I love a nice, subtly modified bike that enhances the bike’s original strengths and this is very simple, but still looks like the original article. This build includes an uprated engine and suspension updates that should provide excellent handling.

1973 Yamaha RD350 L Side

While Kawasaki was busy building hairy straight-line rockets and Honda was busy making bikes Swiss-watch internals at everyman prices, Yamaha was creating its own niche, building middleweight two-strokes that provided a very complete package that included that elusive quality: handling.

1973 Yamaha RD350 Dash

The RD series of bikes epitomized that philosophy, with a 347cc two-stroke parallel twin that put a real-world 40hp through a six-speed gearbox that made the most of the relatively narrow powerband. A powerful front disc allowed the lightweight bike to stop quickly, and frame geometry derived from the TZ race bike gave the bike very nimble handling. Concessions to day-to-day use included Yamaha’s “Autolube” oil-injection system that made fill-ups at the gas station much simpler, since the rider no longer had to carry around two-stroke oil…

This 1973 YAMAHA RD350 has fewer than 200miles since rebuild. starts easy and has that awesome two-stroke sound coming out of the spec2 chambers! EVERYTHING was completly disassembled, rebuilt, painted or polished. The crankshaft was rebuilt, stage 2 porting, larger RZ intakes,32mm mikuni vm jetted for pre-mix, I have the work orders from spec2 with all the details. Franks fork tubes with racetech springs and cartridge emulators up front and works performance shocks out back. the rolling chassis went to G.M.D. computrack to check alignment, yup… it handles awesome! Fuel tank is N.O.S. 77 yamaha SX, along with a ton of nos,oem, and performance rd parts.I have just over $10,000.00 in receipts, they will go with the bike for future reference of suppliers used for the build.

With a $3,200 starting bid and just two days left with no takers, I’m a little surprised. I’m not an expert on these so I can’t speak to its originality, but it seems to be a very well-prepared little bike that really captures the spirit of the era. Luckily, I don’t have a spare $3,200 lying around to buy another bike, but I’ve been aching to buy into the two-stroke club, and this looks like one that would tempt me.

Super-Clean Custom: 1977 Yamaha RD400 for Sale

1977 Yamaha RD400 R Side Front

So hands up if you think the whole cafe racer thing is played out! I do love the democratic nature of the café racer movement, the democratic nature. You can spend as much or as little money as your imagination allows, and build your dream using any brand machine you want. But the thing that makes is so cool is the exact thing that makes it so cliché: everybody with a battered old bike, a hacksaw, and some flat-black spraypaint can get in on the action.

But, every once in a while, a bike comes along that shows just how the whole thing got legs again. And this cool, relatively simple Yamaha RD400 is one of those bikes.

1977 Yamaha RD400 R Side Tank

By the late 1960’s, Japan had proven that it had the engineering expertise to take on the established brands from Europe and America and was busy crushing them under their heel in terms of sales. They were inexpensive, featured sophisticated engines, and were much more reliable than their rivals. But the one area where they generally couldn’t compete was handling: bikes like Kawasaki’s Z1 were very fast in a straight line and merely competent in the corners, while their H1 earned a reputation for being downright treacherous. For most street riders, that was fine, and Harris, Spondon, and Rickman could whip you up a new frame if you really needed to go around corners.

1977 Yamaha RD400 R Side Engine

But there were some notable exceptions to this, and Yamaha’s line of middleweight two-strokes combined playful, two-stroke punch in a lightweight package that made it the ride of choice for backroad-burners and aspiring racers: while heavier than the track-only TZ, it featured that bike’s racy geometry, strong brakes, and a six-speed gearbox. Worry-automatic oil-injection helped keep two-stroke hassles to a minimum.

From the original eBay listing: 1977 Yamaha RD400 Custom for Sale

This 1977 Yamaha RD400 custom is a real head turner!  People will stop you all the time to ask about it!  This was professionally built by Motohangar in Vienna VA.     The bike was completed in June of this year.  Bike is a total, ground up restoration and performance modded machine.  It was a feature story on the Pipeburn website on June 16th 2014.    It was also featured on Yamaha USA’s Facebook page where they called it “a masterpiece.”  If you search it online you will see that it has been re-posted to dozens of enthusiast websites around the world.  Take a minute to check out the feature story on Pipeburn where the builder details the build process and there are lots more photos.    

Bike has fewer than 100 miles on it since rebuild and is absolutely immaculate.  Starts beautifully and sounds like two-stroke heaven due to the hand built Jim Lomas race pipes. Pat at Motohangar has built a number of show stopping bikes over that last few years, including the best in show “Honduki” bike.

This bike has been described as a 70’s LeMans style resto mod due to its stunning paint and graphics.  Everything was completely disassembled and rebuilt and repainted–engine cases are beautifully detailed, frame is freshly painted, wheels were blasted and painted, new seat pan and tail section custom built (oil filler relocated to top of tail section)  custom LED tail light fabricated, neutral and oil warning lights relocated into top triple.

Vintage Smoke rearsets–which include a Brembo rear caliper, Jim Lomas pipes, clip on’s, Frank’s fork tubes, new Dunlop tires, new Assault rear shocks, new chain, new brakes, cross drilled rotors– the list goes on.  This bike is far superior to a brand new RD.

This bike is very fast and responsive to the throttle.  It will put a smile on your face every time!  It sounds like a crazed pack of hornets coming down the road!  Seller has current Virginia title.

Very clean and striking, this is the kind of custom that emphasizes the original bike’s style, while doing its own thing. The taillight is very cool and nicely done, if a bit overstyled, and I love the warning lights integrated into the top triple. I assume the “MH” on the engine is for “MotoHangar”, although I could do without that particular detail…

1977 Yamaha RD400 Tail

At $6,300 with the reserve met and a couple days to go, I’m very curious to see what this goes for. If this stays anywhere in that range, someone’s getting a serious bargain for a very classy, one-of-a-kind motorcycle.

Vintage Race Bike Week Continues: 1975 Yamaha RD350 Road Racer

 

1975 Yamaha RD350 Racer L Side

It’s raining race bikes this week! This example is a fully race-fettled, faired version of the popular, fast, and nimble Yamaha RD350. Streetbikes didn’t feature this example’s large, aerodynamic fairing, or that very interesting bladed trefoil tail section.

1975 Yamaha RD350 Racer L Rear

What streetbikes did feature was a lightweight parallel twin two-stroke that pumped out a genuine 40rwhp, making it a very quick middleweight sporting machine with good handling and reliability. The transmission contained six speeds, and the RD350 used an automatic oil-injection system so owners didn’t have to ride around with a quart of two-stroke oil in their backpack… Although this bike has had its suggestively-name “Yamalube” system removed in the name of simplicity and weight-savings.

1975 Yamaha RD350 Racer L Front Engine

Frames were similar to the TZ series of racebikes and the RD’s handling was excellent, although the RD was much heavier than the purpose-built machines. Many RD’s were used as club racers and the bike bucks the prevalent image of 1970’s Japanese machines being fast in a straight line only.

And while the brakes look a bit underwhelming compared to two-disc set ups, the system was powerful and well-regarded at the time.

This is a RD 350 set up for Vintage Road Racing.  I purchased this bike to fulfill an old dream of road racing.  I was 55 at the time.  I got my Motorcycle Competition License and headed for the track.  I only ran the bike on Track Days (a couple of times, maybe 20 laps).  I had a blast !  My mind was 18, but my body was not.  Track time proved to be too expensive.  I parked the bike in my house(well covered) drained tank and prepped it for storage. Now is the time for someone else to have FUN !   I just moved it to my shop and cleaned it up.  Bought new battery and added gas/oil mix.  It fired up in a couple of kicks.  Revs and runs fine. I’m the third owner that I know of. 

Now for the list of goodies that make this bike outstanding.  The bike was red when I purchased it.  I have painted it Classic Yamaha Yellow with black and white racing stripes(Basecoat/Clearcoat).  It has about 300 miles on the Top End, which was rebuilt with Genuine Yamaha parts by the previous owner.  It has not been ported.  Stock carbs with Boysen Power Reeds, 140 main jets(could go smaller), AirTech full TZ fairing and anti-draft seat and windscreen(with a few scratches), metal front fender(unknown origin), Raask rear sets, Spec II expansion chambers, Tapered steering head bearings, Brass swingarm bushings, NHK steering damper, ProFlo/K&N air filter, New aluminum clip-ons, Excel Aluminum rims, Dunlop K series tires(little wear), Nissin front master cylinder, New battery(under rear part of seat), Koni chrome steel rear shocks(not in production anymore), High Power coils w/NGK spark plug leads(new), Newly installed custom Sprocket Specialist 14 tooth front, 42 tooth rear for use with lighter weight RK XSO 520 Chain(all new).  The oil pump was removed by previous owner, I use 32:1 premix Yamalube.

These are very popular vintage rides, and only their high production numbers is keeping prices down. Set up for the track using quality components, this may not have the rarity or outright speed of a genuine TZ, but should be pretty good fun for less money, and the buzzy little 347cc motor can be hotted up to make significantly more power.

1975 Yamaha RD350 Racer R Engine

I’m sad to hear the rider doesn’t feel his body can keep up with his youthful enthusiasm, but his loss is your gain! This bike is no battered track-rat, and it looks nice enough to ride or display, although it seems to waste all that nice prep work by parking it up somewhere…

Any of our loyal readers know anything about that tail section?

Tiny Things In Tiny Packages: 1975 Yamaha TA125 for Sale

1975 Yamaha TA125 L Side

After Yamaha withdrew official support for the 125 class in the late 1960’s, serious racers were left in the lurch. If you wanted to go racing on a small Yamaha, you went out and bought a roadgoing YAS1 or an AS2. Then you purchased one of Yamaha’s GYT [“Genuine Yamaha Tuning”] kits that included carbs, heads, an upgraded clutch, exhausts with expansion-chambers, and a variety of sprockets to suit different tracks, installed it all, then took your modified streetbike to the track!

1975 Yamaha TA125 L Side Engine

Built from1971-1975 the Yamaha TA125 was a production roadracing machine for sale to the general public. Although it was clearly a track-only bike, Yamaha did not put the effort into this machine that they did with their larger 250 and 350 racing motorcycles, and quality of components and the overall package was somewhat lacking in comparison: although this may have been a pure racing machine, it shared many parts with the AS3 on which it was based, and performance suffered as a result.

1975 Yamaha TA125 Dash

But that shouldn’t really matter in this case. This one still features period tech-inspection stickers and is clearly a bike for collectors, not racers: it would require significant time and resources to make it track-worthy, and that custom-painted bodywork would be a shame to mess up. In addition, these weren’t really the best of the breed, and their street origins showed. Track-rats are better off sniffing around elsewhere.

1975 Yamaha TA125 R Engine

From the original eBay listing: 1975 Yamaha TA125 for Sale

I purchased three bikes from a fellow who was closing his machine shop several years ago. Three bikes were stored in the rafters of his shop on a pallet, if I wanted one I had to buy all three. I sold the Penton to a collector strait away as I wanted the TA 125’s. The bike I am now offering has not been restored, I cleaned it up and checked the timing, put some fresh pre-mix in the tank and started it up. We gave it a blast down the road and then put it up. I drained the tank and carbs and left the oil in the trans. So there you have it, an un restored roadracer with AFM tech inspection stickers still on it. You will no doubt note several modifications to the bike, they were done by the original owner back in the day. I have not modified any part of the bike, I respected the bike’s patina. You will note this is a no reserve auction, the bike is for sale. Have fun bidding on this rather rare bike.

A very cool motorcycle with tons of patina and vintage details, it’d be a shame to do anything to mess it up or change it in any way, although I think personally, I’d probably want to get it to run at least, just to ride up an down the street and hear its little buzzsaw snarl.

I just wish I had a lobby or an office where I could display something like this…

1979 Yamaha Daytona Special

The world was changing, and when the calendar flipped from 1979 to 1980, one of the things that did not make it was the street legal, 2-stroke motorcycle. This 1979 Yamaha Daytona Special was a one year only production bike which began as a celebration of Yamaha’s success at the Daytona track. It became the last year 2-stokes to be sold for the streets of America.

From the seller

  • One of a kind 1979 Yamaha RD400 Daytona Special.
  • This is the only year the Daytona Special was made and the last year that Yamaha made the RD 400.
  • Fitted with a custom modified TZ250 fairing in factory works bike colors.
  • Other features include: Expansion chambers, fiber reeds, clip on handle bars, custom built rear sets (with buddy pegs), Michelin racing compound tires.
  • Second owner.
  • 16,669 miles.
  • New battery, recent brake fluid flush/bleed.
  • Always garaged and covered. Rarely ridden since the early 90’s. Last licensed 2012.

Yamaha had first offered the the RD350 in 1973,  and had used much of what had been learned on the race track, and put it into Yamaha street bikes. One of these lessons was the use of a reed valve induction system. This offered the street bike a much wider power band, and additional air/fuel to help keep the piston cool and moving up and down. Nothing ended the joy of riding 2-strokes then a seized piston. 1975 was the fist year of  the RD400 and with the increase in displacement came improvements in the  electrics, handling, and miles per gallon. Further tuning had also tamed the the engine a little more.

Back of the baseball card

1979 Yamaha RD400F Daytona Special
Claimed power: 30hp @ 6,500rpm
Top speed: 98mph (period test)
Engine: 398 air-cooled 2-stroke parallel twin, 64mm x 54mm bore and stroke, 6.4:1 compression ratio
Weight (w/have tank fuel): 372lb (169kg)
Fuel capacity/MPG: 4.6gal (40-50mpg)

 

Kenny Roberts and Mike Baldwin were both Yamaha riders and both were dominating AMA racing in the United States. In 1979 the RD400F Daytona Special was commissioned to celebrate Yamaha’s winning ways at the famous track. But with increased EPA restrictions and regulations, the Daytona was also the end. The new regulations required extra hoses, valves and do dads to cut down on emissions. A large request from an engine designed to create as much blue smoke as power.

Honest seller notes

Now the bad stuff: Speedo is sluggish (I have been told the oil in them gels from infrequent use), It is missing the headlight high/low switch (it is set on low beam), the seat is starting to separate at the front seam and is showing some checking and one small crack (see picture), one small dent in lower front fender.

$_57 (5)

The seller of this 1979 Yamaha Daytona Special added a great full fairing to this last hurrah of 2-strokes in the US. The RD400F had evolved from its early incarnations to become a much smoother and less dramatic motorcycle that could have become so much more. But with the world turning from 2-strokes to 4 strokes, Yamaha ended an era on top. BB

Many of the bikes that I bring to these pages are eye catching. Flipping through eBay, this 1977 Yamaha RD400 King Kenny replica in yellow and black, and full fairing defiantly stopped me. What I was hoping for was a story about how this bike came to be.

From the seller

This is a race bike for the track or street. CA clean titled, plated  and registered. It has new wiring, new brakes, new top end rebuild with pistons, rings and seals. All professionally done at Motorcycle Performance in L.A. It has the rare Moto Carrera fairings and rear sets.

 

$_57

Was this a commissioned build? Was it passed on from the builder to the seller as just another sale? There would have been so much effort put into the build, I would hope the seller would add more about it.

$_57 (1)

 More from the seller

It is modeled after the 1978 championship bike. This is a rocket ship for the street not for the faint hearted.

Its a kick start that always turns over on the first or second kick. Has electronic ignition conversion.

What else.? The reserve is low so bid happy. I can help buyer with shipping company I use and so do all my buddies.

This bike MUST GO. Baby and broken collarbone bills force the sale.

 

What I can see from the few pictures is that there is a great big vented front disk brake. Is this a RD400 unit that spent some time on a drill press, or has a bigger and better unit sources from the Yamaha bins? If it is bigger and better, was a bigger, better, stronger front end added? The rear shocks look to be 21st century, but the rear disk looks to be what you would find on a stock.

$_57 (2)

The seller says that this 1977 Yamaha RD400 is a tribute to Kenny Roberts 1978 year, and not a bad year for the man who would become King. This was the year that Kenny became the first American Grand Prix Champion. He would race the 250cc, 500cc and Formula 750 series, entering as many races as possible to learn the unfamiliar track of Europe as quickly as possible. Beginning with a victory by lapping the field at Daytona, and ended with Kenny Roberts finishing in front of Barry Sheene at the Nürburgring. When you throw your leg over this bike, will you imagine yourself at Daytona, or the Nürburgring? BB

From the factory, the TR3 came with 34mm Mikuni carbs, a 6 speed transmission, and a HUGE four leading shoe front brake. One of the draw backs of a 2 stroke engine, is there is zero engine compression breaking, so prior to disk brakes, you needed as much brake shoe material as possible.
