Little Blue Bomber: 1975 Honda CB400F Super Sport for Sale

1975 Honda CB400F R Side

The introduction of Honda’s CB750 in 1969 did more than simply redefine what a range-topping bike could be. It heralded an onslaught of sophisticated, reliable machine across their entire range: while sporty midsized offerings from the other Japanese manufacturers were often quick and nimble, but powered by peaky, noisy, smoky two-strokes, Honda used sophisticated overhead-cam twins and fours. In fact, their direct competitor for the famous Yamaha RD350 was this bike, the four cylinder CB400F. 1975 Honda CB400F L Front

Powered by a bored-out version of the 350, the 400F engine actually displaced 408cc, and the bike featured a relatively novel six-speed gearbox, something nearly unheard of outside racing circles in an era when most bikes still used only four.

The Honda couldn’t hold a candle to the RD in terms of quick and dirty speed, but it beat the little smoker hands-down when it came to sophistication. Unfortunately, the sportbike market wasn’t especially interested in refinement, so the Honda didn’t sell all that well when new, with buyers in the middleweight sports market opting for the light weight and personality of the Yamaha.

But while the Honda was much heavier, handling was still excellent, and riders of the period found plenty of success on track, with race-prepped bikes capable of true giant-slaying ability and top speeds of over 130mph.

This 1975 Honda 400 Four Super Sport is equipped with a side stand and a center stand which is handy for maintenance. It also has an electric start & a kick start. This is handy if the battery is low, as the starter robs the voltage to the ignition coils. After starting the bike from cold, it needs to warm up on part choke for a few minutes before setting off, or you could find yourself fumbling with the choke whilst riding.

This little guy pulls well from the start (even with its peak power of 37 bhp at 8,500rpm and redline at 10,000 rpm), and with 6 gears to choose from you’ll find your left foot is kept busy if you want to make the most of it. It accelerates well from 0-70 mph, which is the range where most riders will find themselves on this urban super sport. The seating position is slightly bent forward, giving a dominant street fighter feel. The bike handles very well at all speeds providing good cornering and a comfortable ride, and would make a great city commuter anywhere in the world.

This well preserved 1975 Honda CB 400 F only has 12,655 miles on the odometer. The VIN number is CB400F-1027692, Date of Manufacture is 03/75, and Engine ID# is CB400FE-1028229. It is in very nice condition. The bike starts, runs, and shifts very well. The bike is all original with the following exceptions – which were made to get it roadworthy for the new owner:

New “Varnish Blue” paint on gas tank and side covers (professionally done and very nice)

New chrome exhaust muffler

New dash lights/ console  (replaced with new)

New seat cover  (replaced with new)

New tires

New cables for throttle, brake and clutch

New master cylinder

New switch gear for starter and kill switch at throttle side of handlebar

We have gone through this bike and cleaned it from top to bottom and performed the following services:

Installed new brake pads and rebuilt front caliper (with new brake fluid)

Repainted front brake calipers

Polished all chrome parts and accessories

Cleaned and tuned all 4 carburetors

Replaced all fluids

All lights and electrics work perfectly, and the horn work so it will easily pass Texas vehicle inspection. There is not a bit of grease or dirt on this bike anywhere as it was given a very thorough detailing, even in the places you can’t see.

1975 Honda CB400F R Side RearThis one has been repainted and looks to be in excellent physical and mechanical condition. The seller also includes a nice video of the bike being started and running.

These are great little bikes, and can still be found for very reasonable prices. They make excellent “starter classics” since they’re physically on the small side, are reliable, and have decent parts availability.

The Littlest Superbike: 1976 Honda CB400F


1976 Honda CB400F R Front

Introduced at a time when “middleweight” machines almost exclusively featured single and twin-cylinder engines, Honda’s little CB400F was really a “because we can” middle finger in the face of the competition, a demonstration of engineering mastery. Out of the box, it offered no performance advantage over twins, singles, and two-stroke alternatives: the increased weight of the package was only partly offset by the additional power that higher revs allowed.

1976 Honda CB400F Dash

But that was hardly the point. Introduced in 1975 and built until 1977, this was really a more sophisticated alternative to those bikes that offered a smooth, silky 408cc four-cylinder powerplant and a six-speed gearbox when bikes from Britain generally had only four speeds…

1976 Honda CB400F Tail

Unfortunately, that same complicated specification led to relative high prices for the class, and that resulted in poor sales. If you wanted cheap speed in a package that handled, Yamaha’s RD bikes were the ticket. But Honda’s little four offered a much more refined package. With a distinctive four-into-one header that clearly advertised the bike’s specification, the rest of the bike was relatively conservatively styled.

1976 Honda CB400F L Tank

While these weren’t especially fast right from the factory, legendary Honda durability allowed tuners to wring some fairly insane power from these for the race track… Tuner Kaz Yoshima built CB400’s to compete against much larger bikes and his could hit 130mph!

I’ve reluctantly decided to sell my 1976 CF 400F Super Sport. A recent total shoulder replacement and a dangerous increase in local traffic have curtailed my riding pleasure. In an effort to accurately describe this motorcycle, this description may get a little tedious, but I would rather give interested parties an in depth look than leave out any important details. If I left out any information, please let me know.

History: I purchased this bike in September 2005 from the original owner’s family in Tennessee. It currently has 11,008 miles, it has a clear South Carolina title, and the engine and frame numbers match. It has never been laid down. It is in very good to excellent mechanical and cosmetic shape. When I acquired the bike it was obviously very well cared for and the previous owners kept detailed records since the original purchase. During my ownership I have kept up regular service and maintenance, and always stored in a climate controlled garage. Documentation includes original written sales receipt from dealer, most maintenance records, original owners manual and warranty booklet (in original plastic pouches). Also included is original toolkit that appears to have 10 oil drain bolt washers still sealed in a plastic bag. Also from the previous owners is a binder that contained a xeroxed copy of a shop manual along with the maintenance records and parts purchased in it. There were a lot of OEM items supplied with the motorcycle when I bought it that I cannot find receipts for, but they were in OEM marked sealed bags. Some were used in subsequent maintenance described below.

Items Not Original: The battery is about 7 months old and sale includes a hardwired battery tender with quick connect. The original tires were replaced by my local Honda dealer at 10,890 miles, so they have 120 miles on them. The new tires are Bridgestone Battlax BT-45’s. I also had the original chain and sprockets replaced at the same time, all OEM replacements. The previous owners had replaced the master brake cylinder/reservoir (OEM). Included with my purchase of the bike was a new starter/kill switch assembly as the starter button had an intermittent short, a very common issue on these bikes. After installing it, the new assembly (and brake reservoir) did not match the patina of the old turn signal assembly on the left-side of the handlebars. In an effort to make them all match (they look like they have a bronze/black anodized coating), I replaced the left-side turn signal assembly (OEM) again with parts I acquired with the bike. The brake and clutch handles look more like a pewter finish so they didn’t need replacing, they are original and still have the original heavy plastic coating and rubber tips. I still have the old left and right assemblies that are included with the sale, but not the master brake cylinder.

The listing includes lots of additional history and detail. Keep in mind the “numbers matching” issue that the seller mentions in his listing, although it looks like this really won’t be any problem for a potential buyer. Bidding is pretty active, so it seems like buyers aren’t being scared off.

At $2,949 and a couple days left on the auction, this looks like a good deal for such a shiny, original machine with only 11,000 miles on the clock. This is another one of those bikes that I’d love to pick up, if I only had the space to keep one. A great introductory classic, or a bike for someone who wants to spend more time riding than wrenching!

1975 Honda CB400 Yellow Right Side

Looking for all the world like a 4/5 scale CB750, the Honda CB400F  to me represents a serious bargain in classic bike ownership. Various Japanese twins might be cheaper, but those really seem to be aping the classic British Nortons, Triumphs, and BSA’s. Honda’s fours were definitely doing their own thing, and doing it well.

Honda’s original four-cylinder bike, the CB750 was introduced in 1969 and the design led to a whole range of machines: a 350, a 500, a 550, and the 400.  Made between 1975-1977, 408cc motor found in the 400F was backed up by a relatively rare outside of racing, six-speed gearbox, and the beautiful headers remain a work of art. The Hondas were pricier and heavier than the bikes they were pitched against, but were smooth, reliable, and stable.

This one looks to be a great example in well-cared-for condition, although the over-exposed photos don’t really show it off to the best effect: these are great-looking, classic machines in the flesh.

It seems like these are still undervalued, compared to the 750’s. They were the refined choice at the time: in an era of one and two-cylinder middleweights, the 400 offered unparalleled specification. In a number of ways, they’re actually more sophisticated than their bigger brothers: 4-into-1 exhaust, 6-speed transmission compared to the 750’s conventional dual exhaust and five-speed.

These have begun to escalate in value, but are still available for a relative song, and parts are readily available, making this great for collectors who want something they can actually ride, not just show.

1975 Honda CB400 R Side

If you’re looking for a sophisticated 1970’s bike, and Honda’s CB750’s are starting to get a bit rich for your blood or are simply too cliche, can I recommend something perhaps a bit…  Smaller?  The revolutionary CB750 four-cylinder spawned a whole range of Honda motorcycles of varied displacements, and what the CB400F lacks in outright grunt, it makes up for in sophistication.

1975 Honda CB400 Dash

I love these and, although they’re beginning to get the attention their classic status and technical specification deserve, their prices remain low.  The little CB400F featured very sophisticated mechanicals for the time: a 408cc four-cylinder motor and a six-speed transmission.  At the time, few bikes of any displacement had more than two or three cylinders, and even fewer had more than five forward speeds.  And that distinctive, four-into-one exhaust really tells you this is something a bit different.

1975 Honda CB400 Mirror

But while the technical specification makes the bike stand out now, at the time, it really just added weight, complexity, and expense: Yamaha’s two-stroke RD350 could have it for lunch.  But time has been kind to the CB400F, and folks looking for something a bit less raucous and high-strung than the racy two-strokes have a more refined option here.

17731 miles. Perfect running motorcycle. Carbs have been cleaned, new tires, brake lines, gel battery, and runs GREAT!!  This motorcycle has been in a collection for the past 6 years. Always stored inside. All original except for tires, grips and mirrors. The original paint is a bit faded on the tank but there is no rust inside, one very tiny dent on top. Always garaged and adult owned. No disappointments here. Hate to sell from my collection, but it’s time to cut down the inventory.  Please call with any additional questions. I can help arrange transportation.

I really love these as beginner classics: they’ve got a simple style, they’re pretty inexpensive, parts are available, they’re reliable, sweet-running, powerful enough to keep you ahead of traffic, and very cool.  This one is still pretty darn cheap, and looks to be a good buy.  It’s even got a very nice set of cafe-y bar-end mirrors already fitted!

1975 Honda CB400 L Side2

This little Honda CB400F comes from one of our faithful fans: Gilbert in LA.  His bike looks to be pretty stock and in great, unrestored condition.  It even includes the original tool kit!

Honda built their little 408cc superbike for just three years, starting in 1975.  Normally, a bike of such diminutive displacement would be powered by a thumping single or a vibey little twin, but overachieving Honda gave its CB400F four whole cylinders as indicated by the wonderful 4-into-1 headers.

1975 Honda CB400F R Side Low LA

The bike’s sophisticated specification and complexity made it heavy so it was no road-burner, but its relatively-rare-for-the-period 6-speed gearbox allowed it to at least stay in the hunt, and road racers took advantage of its durable construction to wring competitive power out of it for the track.

As is so often the case with cult-bikes, the machine did not sell especially well initially: if speed was what you wanted, you could get it cheaper, lighter, and wilder from the two-strokes available at the time.   But the Honda’s mechanical sophistication, high build-quality, and relative rarity make it desirable today.

A Reader’s Ride: 1975 Honda CB 400F Super Sport

For Sale: 1975 Honda CB 400F Super Sport

From warm and sunny San Diego, CA comes this fantastic survivor: a 1975 Honda CB400F Super Sport. CSBFS and RSBFS follower Ryck pinged us about having to put his pride and joy up for sale – and we thought that this is exactly the kind of bike that CSBFS readers would love to see.

The Honda CB400F is a classic sport bike icon. Largely regarded as a technical tour de force, the original 400F was introduced in 1975 and ran through 1977. From a marketing perspective, the little 400F made little sense; bigger bikes were all the rage, and Honda’s own CB750 and CB550 Four models were displacing the British invasion. In reality, Honda was flexing some serious motorcycle muscles with the little Super Sport, proving to the world that it had the manufacturing capability to bring such wonders to life.

The most visual element of the CB400F was the swooping four-into-one exhaust system as seen in this photo. Together with the rest of the cafe-racer inspired styling, the impressive four cylinder, four-stroke engine, a six-speed transmission and a front disc brake, the 400F both looked good and performed well.

From the seller:
You are bidding on a un-restored museum quality example. All stock from the paint down to the original Bridgestone Super Speed tires. The chrome has some minor pitting and spokes have some surface rust and the left side engine covers have some cosmetic damage where fuel leaked at one time. The only thing that is not stock is the muffler and the headlight brackets and I do have the stock headlight bracket/turn signal assembly and the rear turn signals-from 36 years of storage/moving around one of the rear turn signal brackets is bent slightly and the front ones just look goofy so I left them off. I rebuilt the carbs with oem Honda gaskets, adjusted the points, timing and valves this summer. The engine runs perfect- all they way up to the red line- well not quite red line I took it up to 9k and I only did that one time myself just to test the engine and let me tell you it just makes the most glorious sound from that 4 into one exhaust!!! Clear title and it is currently registered and insured-I ride it at least once a week around the neighborhood and take it to the local bike nights and it always draws a crowd. The gas tank and side panels are original paint and have not been retouched in any way there is one very slight dent on the top of the gas tank – you have to really look to see it- I couldn’t even get a picture to come out good enough to see the dent. The handlebar switches are original and still have bright red markings and every thing works as it did from the factory, there is only some slight fading on the master cylinder body and the paint is coming off the front caliper. It comes with the tool kit,owners manual and it still has the tool box cover. This is a once in a lifetime buy and there is no reserve.

There were two different generations of 400F, with only minor variations. Today’s featured bike is a Gen I model. Color choices were Red or Blue for Gen I machines, and Red or Yellow for Gen II bikes, with different font and lettering styles on the tank and side panels. Both generations are considered collectables, and prices have been creeping up from the basement into reasonable levels as of late. With low mileage and in clean, presentable condition, this bike is definitely one to consider.

A desireable model in true “survivor” condition with low miles – that is a CSBFS find. The fact that this bike is located in “no rust” California is just icing on the bike collection cake. Check out the no reserve auction here. Good luck, and don’t forget to tell ’em you found it on CSBFS!
