Baby Sport: 1971 Ducati 450 MK3 Desmo for Sale

1971 Ducati 450 Mk3 Desmo R Side

For fans of Ducati’s sports singles, this Mark 3 450 Desmo is the top of the heap, and shares that gorgeous orange-yellow paint with the bigger 750 Sport. But, unlike that model, the 450 Desmo features Ducati’s desmodromic system.

While “Ducati” and “desmodromic” have become synonymous today, the system didn’t feature on all of their models until the Pantah motor of the 1980’s, when that motor was used in both large and small displacement applications. The system was mostly used on range-topping sports models like the Super Sport twins and Desmo singles. Other manufacturers, including Mercedes, have used similar systems, but Ducati’s design was created by the revered Fabio Taglioni and first applied to their 1956 125cc race bike.

Ironically, the system probably had more practical benefits when it was introduced on Ducati racebikes in the late 1950’s, although the precision tuning does still have some benefits. If you’re not familiar, a desmodromic system uses cams that both open and close the valves to eliminate valve float and allow for very precise tuning. The fact that the valves are being closed in a controlled manner, instead of just being slammed closed as fast as a spring can manage, permits steep cam profiles that wouldn’t normally be practical.

In 1968, Desmo performance was introduced to Ducati’s roadbikes on the Mark 3 250 and 350 bikes, with the 450 available in 1969. Interestingly, the 250 and 450 models were far more flexible on the street: the 350 had a much more highly-strung demeanor and was ready to go racing, nearly right out of the box.

This same seller has had a number of really nice bikes up for sale on eBay of late that we’ve featured, including that very, very cool Guzzi racer from last week. I’m not sure if he’s liquidating a collection, but his bikes are amazing, and he’s popped into the comments to answer questions from time to time, so don’t hesitate to ask questions at the original listing or in the comments section.

Single and Italian: 1970 Ducati 450 Mark 3 for Sale

1970 Ducati 450 Mark 3 R Side Front

This fine Saturday finds this Ducati 450 Mark 3 looking for a home. Although Ducati no longer makes single-cylinder motorcycles, they were the company’s bread-and-butter until the small-displacement Pantah twins arrived in the early 1980’s. The bevel-drive twins grabbed much of the glory, but their smaller, simpler siblings have a long history on the street and in competition. In recent years, collectors have been gobbling these up and prices have been increasing accordingly.

1970 Ducati 450 Mark 3 L Side Detail

The singles were available as sporty racers, practical standards, and even dirt bikes, with a range of displacements from 160 to 450cc’s. They were sophisticated machines, with a tower-shaft driven, single overhead-cam. The 450 Desmo models remain at the top of the heap, but bikes like this 450 Mark 3 are much sought-after as well, with displacement that allows for real-world riding and even highway use.

With just over 24 hours left in the auction, bidding is up to $4,850 with the reserve, unsurprisingly, Not Yet Met. The Buy it Now price is set at $8,995 which seems reasonable for a 450 Mark 3: while smaller singles can definitely be had for less, the 450’s have been steadily increasing in value. With free shipping to most of the US at that price, I’m a bit surprised there’ve been no takers, since the bike looks to be in pretty nice shape. Any Ducati fans out there care to comment?

1967 Ducati Mark 3 Vintage Racer

1967 Ducati 250 Mark 3 Race Bike L Side

With all the laurels they’ve earned for wins on track and ink expended, or keys keyed, to express the love for the raucous bark of their v-twin motorcycles, it’s easy to forget that Ducati, like most manufacturers, got their start making single-cylinder motorcycles.

1967 Ducati 250 Mark 3 Race Bike R Side Front

For much of the motorcycle’s history, they were practical, inexpensive transportation first, racing machines a distant second, and you can’t get much more simple and reliable than the good ol’ single-cylinder. “Thumpers” are simple to design and manufacture, have fewer moving parts to break or need adjustment, and can be made in a huge range of displacements. In addition, their torquey power delivery and strong, friendly character make them excellent tools for the street.

1967 Ducati 250 Mark 3 Race Bike Dash

A small manufacturer couldn’t hope to compete in terms of sophistication with industrial giants like Honda, so Ducati stayed with forms of racing that played to their considerable strengths. While the Ducati Mark 3 may have been only a 250cc machine, the Diana Super Sport was the fastest 250 on the market at the time and could top “the ton” with relative ease. It did not feature Ducati’s now ubiquitous Desmo positive valve operation and used traditional springs, but it was a thoroughbred in every other way.

This example has been fully prepped for the track and includes a metal belly pan, unusual dry clutch, and a four leading-shoe front drum brake from a period Suzuki for some improved stop to go with the engine’s uprated poke.

With just a single bid for $5,999 and the reserve not yet met, it’s unfortunate this bike hasn’t found a buyer yet, with three days to go. It seems like a great turnkey way to get into the vintage racing scene, something I’d really love to do myself.

1967 Ducati 250 Mark 3 Race Bike L Grip

There’ve been a number of really neat vintage racing machines up for sale recently on eBay, track bikes and race-eligible machinery that looks well-prepared and ready to go. These seem like they’d be a good bet for a buyer: obviously used harder than many pampered street machines, the upside is that they’re owned by gearheads and racing requires certain minimum safety and therefore maintenance standards be met. If you’re trusting your life to something you’re going to be pushing to the limit, your standards for just what constitutes “safe” do tend to go up a bit…

In addition, my personal experience with bikes and cars is that, the more you use them, the better they work. Sitting collecting dust in a garage or showroom is bad for bikes: tires and hoses dry out and crack, gaskets weep, parts seize and rust…

1967 Ducati Diana MKIII

1967 Ducati Diana 250 R Front

Fans of modern motorcycles become so used to the short product cycles of Japanese machines, the two-year grind of mechanical and cosmetic updates to keep the product fresh and moving off of the sales floor. But that all changed with the recent stock market crash. These days, a 2014Yamaha R6 looks virtually identical to one from 2006 except for paint and graphics.

It’s easy to forget how many classic models were in production for years, with relatively few changes. Ducati’s 250 was introduced in 1961 and the machine continued in Mark 3 guise until 1974.

1967 Ducati Diana 250 Carb Detail

The Ducati Diana 250 Mark 3 was lacking in cubes, but not in sophistication. Introduced in 1962 the Diana featured a five-speed gearbox and Ducati’s complex and tunable bevel-drive, single overhead cam engine..

Light weight and a tuned powerplant pushed the 249cc machine beyond the 100mph mark to an as-tested top speed of 104, making it the fastest 250 in the world at that time, and one of the best handling, as well. It wasn’t cheap, but this sort of pedigree seldom is.

1967 Ducati Diana 250 Tool Box

From the original eBay listing: 1967 Ducati Diana Mark 3 for Sale

It is a 1967 English model Mark 3, which replaced the Mach 1 model (simple decal engineering) from that year on & has all of the near-impossible to find original hardware on it: the correct rear sets with the curved brake lever, the smooth fork crown, the proper clip-ons & hand controls, the proper 150 mm headlight & switches. The brake light assembly is original.  The brake light switch is original too. The Veglia tach, drive, & mount are original units, not replicas. 

The engine is the original, proper Mach 1 spec unit, with hot cam & 29mm carb, which has been gone completely through by a competent pro motor bike mechanic.  I had the original header pipe re-chromed & a new header nut. 

My intent was to keep this bike as my special Sunday morning ride unit.  To that end, I did change a couple of things: I replaced the original steel San Remo wheels with perfect Borrani Records (WM1 front/WM2 rear), & had them laced with stainless spokes. The tires are racing compound Avon Roadrunners, never ridden.   The seat is a NOS suede insert Giuliari Mach 1 unit that has never been ridden.  It has the pseudo megaphone that I had Sid Tunstall (well known Ducati specialist) make (with Conti innards to hush it up a bit) & the original NOS front number plate covering the headlight (not shown in photos), it looks exactly like the old brochure pictures for the “race kit”.  One other thing that I did was replace the battery ignition with a magneto unit (“Green coil”) that they had for a brief period of time – my idea being the ability to ignore the issue of worrying about a battery when I got the urge to ride it.  I still have the battery ignition too though.

1967 Ducati Diana 250 Dash

Okay, I’m sold: I have a fetish for those old Veglia tachs, and will probably just buy one online at some point to keep around as decoration, or as an accessory for a future purchase. I love that it basically starts at 2,000rpm and has that little red hash-mark redline.

Bidding is up to $7,600 with the reserve not met and 3 days to go.

1972 Ducati 250 Scrambler L Side

During the 1960’s, Ducati struggled to sell bikes in the USA, left behind in an arms race that really required at least two cylinders to compete with popular machines from Moto Guzzi, Triumph, Norton, and Harley Davidson. Ducati’s roadrace heritage and sublime handling were considered to be of little value and horsepower was king in a country with so many miles of arrow-straight roads. Luckily, the famous 750 v-twin was on its way to salvage Ducati’s fortunes…

1972 Ducati 250 Scrambler Dash

Until that v-twin put Ducati into the “superbike” game, they made do with a range of sophisticated single-cylinder machines with a variety of displacements. The regular 250 had a single overhead camshaft operating the valves via traditional springs: unlike today, only the sportiest Ducati singles of the era featured their now-ubiquitous Desmodromic springless valvetrain. All Ducatis did get the distinctive tower-shaft and bevel-drive arrangement to operate the single overhead cam. Driving power through a five-speed box, the bike offered a blend of usable power and sweet handling that was sadly overlooked in America.

This bike is great condition and runs great.  It has 2 significant upgrades.  The plastic oil pump has been replaced with a metal oil pump that now makes the bike reliable.  It also has the Power Dynamo 12 volt upgrade, which gives a solid state, maintenance free, full electronic ignition.  Now you never have to worry about your battery going bad, as it eliminates the battery altogether.  Just put fresh gas in it and kick it and you’re ready to ride.  Also comes with brand new road tires, napoleon bar end mirror, and H4 headlight.  The tank is in great condition with no dents, seat is in like new condition.  Akront aluminum wheels with trials tires that are on the bike are actually very nice to ride on the street.  This is a very reliable and fun bike to ride with very low miles.  Clear title in hand. 

1972 Ducati 250 Scrambler Seat

It used to be that the non-Desmo and lower-spec, small-displacement Ducatis were still very affordable, and could still be found in restorable condition in barns and sheds. But that’s changing: lots of people snapped up Scramblers and other less-racey machines with an eye to converting them into replicas of the sportier models. Now, as vintage dirtbikes have come into vogue and Ducatis in general have risen in value, they’re being kept original as well.

1972 Ducati 250 Scrambler Tank

The “trials” tires on this particular machine threw me when I first saw it, tricking me into thinking it was some sort of modified Scrambler. The seller is vague as well, mentioning only that it’s a 250, so I’m betting he doesn’t know either. It certainly looks to be in nice shape, with shiny paint and an intact seat, although I’m not sure if they match the bike or each other. The frame, gauges, and tank look like a Scrambler, but those side covers and the seat don’t match that model. So what are we looking at here?  A Scrambler? A Mark 3?

Any of you vintage Ducati experts want to chime in in the comments? Am I looking at more than one bike here?

White, Blue and Red Commando 1975 Norton Commando Mark 3

This bike right here is why I spend my weekend mornings scouring the internets for bikes. Mostly original, unrestored and awesome. This one has the uncommon electric start. It’s as simple as a modern bike. Just pull in the clutch lever (normal clutch, not sprag), kick through, free the plates, open the petcocks, tickle the carbs, turn the ignition on, and push the button. Well, it’s not that simple but if you like classic sport bikes going through 5 or more steps to start a bike is part of the charm; it is for me anyway. I say the more things you have to do to start your bike the better, it keeps thieves from riding off on your bike while you’re in the pub or what have ya.

1975 Norton Commando for sale on eBay

The seller is clear and educated about this bike.

Here is a very good, original Norton 850cc Commando Mark 3 Roadster – exceptionally well maintained since new with many of the most sensible improvements made.   This white with blue and red striping is probably the most attractive of the 850 Commando models.  This machine is in excellent condition, serviced as required and – it starts every time and runs perfectly. 

 I have many of the service records from new and a full binder of technical information including a factory Service Manual, Parts book, original Handbook and service book.  I am the third owner – the previous two, kept good records.

Improvements made: 

  • K&N high-flow Air Filter (the original factory Airbox is included with the machine).
  • Sun Alloy Rims (the original factory chrome rims are included (good condition)).
  • New exhaust pipes.
  • New battery and tires.
  • 3 brush conversion for Electric Starter (works every time).

Chrome, alloy and paint work are in very good condition (for most of its life, it was in Arizona – dry and garaged).  The tank has a couple specks on the paint, but otherwise – near perfect.

Just like the seller says, “sensible improvements”. That’s the kind of stuff that makes this bike just that much better. Very original condition but also rideable. Best combo in classic bikes hands down.

Did you know that Norton Motorcycles won the Isle of Man TT 10 times from 1947 to 1954? Well now you do if you didn’t. If you’re down for buying this bike bring your wallet, no not the little carry around one, the big one under the mattress. I’m guessing this bike will “command” a Hollywood mainstream movie type price.
