Looking for my first cafe project. I was wondering if anyone knew about a 1980 CB 750F Frame. Is it similar to the late 70's models? Does any company or person make a cafe style seat/tail combo for it? If so where would I be able to purchase it? Or should i just look for a late 70's CB.

thank you very much,

Mike

the 1980 cb750F is a DOHC cb750 motor. It does not share much if anything with the earlier SOHC cb750s. The DOHC F bikes were originally designed as a european only roadster style sport-y standard and was only imported to the US as a last minute decision in 1979. The good part about those bikes is they fixed a lot of the shortcomings of the SOHC bikes and they handle infinitely better and are much faster than their SOHC bretheren. Unfortunately the bike is also bigger and heavier. F model supersports are unique in that the frame actually uses thicker tubing than all other cb750s and has more bracing - leading to one of the stronger cb750 frames ever made. The chassis can hold easily over 100hp - something that a SOHC frame struggles to do. The DOHC cb750F shares kindred with the cb900F and cb1100F and there are plenty of speed and suspension parts available.

The bodywork on the DOHC supersports were inspired by late 1970s cafe racers, most notably the tracy fiberglass one piece body, which in turn took its whale tail styling from the honda endurance racers of the day. The bikes are "factory" cafe racers in that regard and have a real late 1970s custom look to them stock (as compared to the kz and GS bikes which were kinda plain). IF you want an older look Benjie has a seat/tail and tank for them but remember custom bodywork is rarely cheap. raask sells rearsets for these bikes and honda had its own "sport kit" for it that had rearsets and low bars (good luck finding one cheap though)

check out cb1100F.net as a good resource for them. There are usually group buys going on for ohlins pieces or euro only pipes

Freddie Spencer got his pro-racing break on a DOHC cb750 honda in the early 1980s. most guys building cafe bikes usually use spenser's bike as a reference point. A lot of the cb1100f.net guys have figured out how to do modern wheel/brake swaps on these bikes which helps the race look.

if you are going to go SOHC instead, then go for the 77-78 F supersports and get a low mileage one (high mileage bikes tend to have valve guide problems). Thsi way you get the uprated brakes and can even swap in the DOHC 1981-1982 twin piston calipers.

Cool vid.
The comentator said he was going 175mph. How do I get my CB750 to go 175mph?

I'm thinking that since I can't even get the carbs tuned right, I have a long way to go for 175.
