one on the back of that. A good quick bike that upset a few GSXR's.

Don't know where the cbx 750s upset a few gsxr's but it certainly was not at the TT.

Trevor Nation won the 750 production class on a CBX 750 backed by Oxford products in 1984.
I was there!

1984 was the year before the gsxr made an appearance the best a Honda got in 85 was 22nd with joey on a vfr 750.

Hello Nick.

In Roger's book, 'Roger and Out' - (page 94), he says he was on a RS750R when he finished second to Joey.

Thank you hurplepelmet. Now that is interesting. I was lead to believe that he was on a V4.
I can't think what the RS750 was based on. A CB750F?

I'm sure the RS750 was a v4, it was based on the original VF750 and had been produced at 750, 850 and, I believe, 920 capacities. I think the 920 was just used for endurance racing.

Production V4 Engine Has Ample Race Potential

In 1982, the VF750 Sabre was followed by the VF750F. While its engine had the same output figures as the Sabre and Magna, heavy engine braking caused rear wheel hop, requiring fitment of the slipper clutch designed for the NR500. The VF750F was also the first production bike to feature a double-cradle frame made from box-section tubing. The incredible potential of this machine was proven when racing versions won the Daytona 200 and many other races around the world. The VF750F was followed by a whole line-up of V-Series machines developed in quick succession, including the impressive VF1000R. In 1982, HRC (Honda Racing Corporation) was established and went on to develop many racing machines based on the VF750F. In 1983 they developed the incredible RS850R. This was followed in 1984 by the RS750R, which won the 24-Hour Le Mans endurance race and many other big races. In addition to its impressive power output, the 90° V4 engine layout eliminated primary vibration, was as narrow as a twin-cylinder engine and had its cylinders cast into the upper engine case. The design of this remarkable power unit was both revolutionary and, in retrospect, very rational. It would form the basis for many successful Honda V4 engines to come.

The vf 750f was a pile of junk ask anyone who worked for a Honda dealership at the time, they where that bad thats why the vfr was so good. Honda realized they had built a pup but put the record straight with the vfr probably one of the best motorcycles ever produced it only really had two things in common with the F thats the name on the tank and the fact that its a v4.

The best part of the V750F was the built-in security cable, which set off the alarm if cut. Another great security device that is no longer available was the net, which encased your helmet and locked through the back wheel. Mike Hail wood had a hand in that product.
