The rule book has been updated with the rule changes and other changes to part A. We are currently discussing procedures for head injuries. This is taking longer than planned. We intend to include the procedure in this revision and have delayed publishing the rules until it is complete.

Micheal, there is no clarification on the Honda Interceptor VF750 as apposed to the VFR750F. I believe that the VF750 is now a period 3 class bike, where as the VFR750 remains in P4 ? Is that correct ?

Only VF750s made in 1982 are eligible for P3.

6. PERIOD 3 SUPERBIKE
All rules in Part A are applicable to all classes. In case of conflict, the Part A rules take precedence
over these rules.
This class is for machines built up to and including 1982 with exceptions allowed where production
continued unchanged, and is open to production based and GP machines. Machines can be run as GP or
GP replica, and superbike style. Any component that is visibly different and/or uses technology not
available within the period must be submitted to the Technical Coordinator for approval.

This is what happens when you mess with the eco-system. The rules would appear to support the eligibility of VF750F models from 1982-1985 inclusive.

I was under the assumption that the Interceptor VF750F did not start production until 1983 ??

The Honda VF750F was a street bike designed by Honda from 1983-1985. It had an 86 hp (64 kW), liquid-cooled, V4 engine which sported dual overhead cams (DOHC). The V4's were started a year before with the 1982 Honda Magna VF750C and Sabre VF750S[2] but were adapted for the VF750F in 1983 by reducing the six speed transmission to a five speed because of the change from shaft drive to chain. This reduced the available space in the transmission thus changing to a five speed.[1]

Because of new AMA super bike class regulations it required that four-cylinder bikes be downsized from 1000cc to 750cc, and the bikes had to be production based. This regulation created the first Japanese "Repli-Racer" the 1983 Honda Interceptor VF750F designed for Honda's American Motorcycle Association (AMA) VF750F super bike. Honda didn't cut corners when making the Interceptor, and made it as close to the super bike as possible without losing its street legality.

Most were unaware that the VF750 was available in 1982 in some markets outside North America when the membership voted out the restriction on water cooled four strokes that had been in place since P3 was created.

No one has asked the Tech Committee to include later VF750s, which would require proof that there was no change between the 1982 model and the 83-85 version.

Any idea where I might find that info ?
