Honda RC 172 tribute

I know I just recently posted this CR750 tribute, but this is really well executed as well. My default is to always give preference to mostly stock and original bikes for this site, but on the other hand, when they’re this well done why not?!

1974 Honda CB350 Four RC172 Tribute For Sale on eBay

Bidding is off to a slow start and hasn’t cracked $3k with 5 days remaining, reserve not met obviously.


From the seller:

Wow selling with mixed emotions my RC 172 tribute bike. It has all the right pieces that are next to impossible to get now….covid and wait times! Started as a super clean 350/4.
Swarbrick hand formed exhausts, Holtzwork hand formed aluminum alloy tank, 4 shoe brake, tarrozzi rear sets, NOS switch gear and grips, proper high shoulder alloy rims, cleaned-up electrics, fresh top end, tuned-up and reliable and ready to ride. Too much to list! Buyer will get full build pics.

Additional information: Yes the bike has removable baffles. If you want that Haliwood wail at 10rpm you can have it!
Yes that is a custom aluminum alloy triple. It’s a work of art.
There is a custom spot for the shorai battery under the seat. You have easy access to the trickle charger wire.

Front vented brake is off of a (period correct) water buffalo. It stops this little bike beautifully. I love the progressive feel as you trail brake into corners.

More questions

The front brake is a 4LS from a Suzuki GT750 – depending upon condition they sell for $500-1000 USD.

Holtzwork alloy tank with Monza cap- 1050 GBP plus shipping/taxes

Front forks from a 70’s CB550- stronger and a perfect upgrade path

Yes you could go to pods instead of Velocity stacks. Carbs will need slight retune.

Yes the original front fender has been worked to be visually more similar to RC fender. You could take it a step further and remove the rolled edge.

Yes this bike would qualify as period correct for vintage road racing.

Faux Racer: 1973 Honda CB350F RC166 Replica for Sale

1966 Honda CB350 RC166 Replica L Side Front

Well this presents an odd opportunity: the chance to talk about two very different bikes in the same article. This 1973 Honda CB350F has been fully rebuilt to resemble the RC166 Grand Prix bike of the mid-1960’s. I used to see a guy at the Trader Joe’s in Los Angeles all the time who rode a bike like this one, all clad in black leathers and a replica “puddin’ bowl” helmet, the vintage-racer equivalent of the ubiquitous Harley “skid lid:” just as stupid, but way cooler.

This bike is intended as a replica of Honda’s RC166, an engineering masterpiece, and I’m not sure it succeeds on that front, although it does manage to be a very nice vintage motorcycle with a strong racing style.

Introduced in 1972 as one of the seemingly endless, smaller iterations of the CB750 four-cylinder, the CB350F was, at the time, a very unusual bike in that most machines this small were twins or singles. The engine was actually undersquare, with a bigger bore than stroke and put 34hp thorough a 5-speed gearbox. Although there were plenty of other bikes in the class that were lighter and less expensive, including Honda’s own CB350 twin, the jewel-like engineering appealed to a different type of buyer, and the bike’s increased complexity was offset by Honda’s impressively reliable engineering.

From the original eBay listing: 1973 Honda CB350F RC166 Replica for Sale

This ’73 CB350F is fresh out of a full engine-out cosmetic and mechanical restoration from the frame up. The best I can describe is that everything is new except Frame, Engine, Wheel Hubs and the Triple Trees. Here is an example of what’s new on the bike.  Avon tires, aluminum rims, stainless spokes, caliper and pads, shock seals and fluid, steel fender, headlights, brake and tail light, license plate bracket, 4 into 1 headers, cone engineering muffler, tachometer cable, clutch cable, throttle cables, clutch lever, throttle assembly, grips, anti vibration bar ends, tapered roller bearing steering neck kit, clip-ons, master cylinder, Airtech-Fairing, seat, seat pan, fuel tank, windshield, chain, rear shocks, rear brake pads, electronic ignition, Antigravity 4cell battery, Antigravity battery charger, regulator/rectifier, velocity stacks, bronze swing arm bushings, point to point wiring. Clean title 14,538 miles. Less than 100 miles since restoration. Has electric start, headlights, tail light and brake light utilizing front brake. No speedo but in 5th gear 3,000 rpm’s = 30mph. 5,000 rpm’s = 50mph and so on. No turn signals and mirrors. The carburetors were professionally restored and I will provide extra main jets sizes. Engine does not leak oil, had new gasket kit installed along with all new fluids. The numbers on the fairing are vinyl and easily removable if you choose.

Compared to the real thing, the tank is suitably long and lean but the whole thing isn’t quite proportioned correctly and doesn’t have the tiny, rounded bum-stop tailpiece of the original. It also, of course, lacks Honda’s absolute shrieking masterpiece of a motor, a straight 6-cylinder, four-valve 250cc machine that belted out 65hp through a 7-speed gearbox. With internals that looked more like the parts of a scale model than the real thing, it’s almost impossible to imagine the skill involved in the creation of this thing in an era before computers and modern manufacturing techniques.

And it worked: in the 1966 250cc world championship, the RC166 won ten of ten races.

Although at first glance this replica isn’t streetable, there’s space for a number plate, a tail light, and the bike does feature a pair of little projector-beam headlamps tucked up between the forks under the nose of the fairing.

The starting bid is $7,400 with no takers yet but plenty of time left on the auction. This is really big money for a CB350, but pretty small money for such a one-of-a-kind custom with a ton of style. This is a very sweet little bike that is more “inspired by” the RC166 than it is an actual “replica of,” but that’s okay: a more authentic replica would probably be much more expensive, and still wouldn’t feature that awe-inspiring engine.

Honda CB350F For Sale

Often dismissed because of its weight and small displacement the CB350f used to be looked at as a bike with no reason in owning. The CB350 twin Hondas are lighter, more powerful and look more like English twins. A lot of people figure why get a four when the faster twin is the same displacement. In my experience the four is a bit of a sleeper, with it’s high revving and smooth single overhead cam. I’ve had a CB350 twin, a CB400f and I have a CB350f in boxes waiting to come up in my rotation of projects. I enjoy the Italian race car-ish four cylinder exhaust over the hollow throat of the twin. I like the smooth, low vibration, high revving four over the low revving vibrating twin. These things I like about the four must be some of the reasons other people like the four as well. I have noticed a trend in the prices of the CB350f’s. A bike that just a few years ago could be picked up for around $1500 is now going for $3000.


I’ve been having a bit of insomnia so I find myself looking at classic sport bikes for sale at all hours of the night. I usually pass over these 350’s because they used to go for cheaper and seemed kind of common. That is no longer the case. I rarely see them on Craigs List and maybe only 1-2 of them on eBay at any given time. I can’t say for sure that they will continue to raise in value in the short term but I can almost guarantee that in the long term these will be fetching some very high prices among collectors. The small fours were produced in a 350cc from 1972-74 and 400cc from 1975-77. The twins were produced for over ten years. The twins might make a better race bike but the fours make a very reliable, smooth runner for going to vintage bike nights and going on short weekend rides.


This 350 is perfectly preserved and slightly modified. My favorite version of a classic. Not so perfect it can be ridden year around without hurting it’s value. Not so abused that it won’t let you ride it. The seller seems to feel the same.


I purchased this classic survivor about a year ago in great condition from the original owner. It had spent its entire life in sunny Southern California always garaged. Sadly after being stored properly for the last 10 years, had ceased to be ridden.

After I got it home and went through all the standard Frankenstein Moto-resurrection processes. (carbs/tank/petcock/brakes/cables/controls/tires) The bike started to grow on me. I had over a dozen candidates for modification and restoration in my shop and decided that this smooth running little four was just what I needed for my daily driver.

I toyed with the idea of turning it into a café racer or maybe a street tracker. The classic lines and the honest patina of this 40-year old beauty won me over so I decided on only period correct, reversible modifications that would enhance the looks while making it a very usable rider. First, I swapped that Hindenburg sized taillight and rear fender for a bobbed 350 twin front fender with a more sensible sized Lucas taillight. Next I changed out the stock bars for a nice set from a CB77 Super Hawk complete with a pair of Amal style gum grips and bar end mirrors. Finally I shortened up the stock blinker shafts to make things a little more proportional. Leaving the Honda emblems on the tank has not helped to clear up confusion between this little four and some of its bigger brothers from over the pond.

I am pleased with what I ended up with, a great looking classic bike that I can daily drive or take off on a 300 mile ride with, that didn’t break the bank or destroy this rare piece of motorcycle history.

This is not a show bike and is over 40 years old. Rides great as is or a good canidate for a full restoration. I reserve the right to end auction early as the bike is for sale locally. These bikes are getting hard to find in good condition. If you are interested you should bid before the end of auction or you may miss out.

The seller and I must be cut from a similar cloth. His description and pictures make me want to get my 350 out of the attic and put it together. If you don’t already have one stashed away this would be a good one to grab.
