Hi there. I just joined this site looking for a seat latch for my bike, and within half an hour it was on its way from the UK thanks to postings by Mongo 44. This is a great site. I bought this bike earlier this year. It was put together by an engineer who, in his younger days, was part of a team who had some success at Bathurst. As a result, he was head hunted by the Japanese Honda racing team, and spent a couple of years there. I have some terrible photos of the bike, which will be the only ones I have of it in its 'original' form. I thought this would be a great start for a cafe racer, which I currently undertaking. Incidentally, I have a 2003 BM Montauk, and brakes on this Honda are comparable. Below is the blurb that appeared on Ebay when I bought the bike. I think it went on at 11.00 pm one Sunday night, and it was mine by 11.30pm.
Up for auction is my "retro" CB750. I bought this bike in March last year from the original custom builder, a well known Australian race bike builder and Mechanical Engineering lecturer. He did a superb job building a beautiful bike from a trailer full of old CB750 parts. He wanted a bike with retro looks, but dynamic modern performance, and in my opinion, he ticked all the boxes. Firstly he totally rebuilt a big valve 1977 CB750F2 engine with all new components, including a NOS Wiseco 836cc "F2 Specific" big bore kit. He installed a Dyna S ignition and Dyna 3 Ohm coils, and he also had all the external engine covers nickel plated for a bit of "bling".
He wasn't happy with the standard F2 carbs, so he re-engineered a set of Keihin 32mm CV carbs to fit, and modified the stock K2 airbox to suit. The result is a super light throttle, instant starting, and excellent fuel economy compared to the stockers. He installed the engine in a freshly powdercoated stock K2 frame, but soon found that the handling and braking left much to be desired, so he machined up a set of custom billet CNC triples with the original Honda rake and trail to suit a set of 41mm FZR1000 forks. He then made special adapters to match the FZR discs to the CB750 front hub, so that he could take advantage of the 4 piston calipers.
Obviously some more modern rubber would help in the handling department, so he fitted new wider alloy rims front and rear (2.5 inch front and 3.5 inch rear) with stainless steel heavy duty spokes. The bike is currently fitted with Bridgestone BT45 tyres, 110-80/18 front, and 140/90-18 rear. Obviously the OEM shocks were not up to the task, so he installed a set of NOS Koni shocks with adjustable damping, and it handles like a modern bike. The tyres are as new, as are the heavy duty EK 530 O ring chain and sprockets.
I've since given it a cosmetic tidy up, with new candy gold paint, K0 repro seat, another new chrome Tranzac 4 into 1 pipe, chrome oil pressure gauge, front fender, chainguard etc. I'm a CB750 "nut" and have owned over 20 CB750's over the last 33 years (I bought my first CB750 new in 1978) and this is the best one that I've owned. It starts instantly, doesn't leak oil, and doesn't blow smoke. It starts, handles and brakes like a modern bike, but it has the simple good looks of a 1970's superbike, without acres of plastic to cover ugly engineering

The only thing that would make it look better is if it was setting in my garage.
