I do have frame numbers for non UK models. If you need to know what model your machine is then send me either the engine or frame number and I will let you know.

Tyre pressures:

The manual lists the same pressures for both rider only and rider and passenger

Front 36psi

Rear 42psi

I have seen instances where people have used 36psi on both front and rear to good effect however I personally would not want to deviate form the stated pressures by more than 3 or 4 psi. For track use it is normal to reduce pressures by 2-3 psi so a 34/38 combination would probably be ok. It is down to how the feels really. Initially reducing the pressures will make the bike feel a touch more ‘squirmy’ in the bends until the heat build-up forces the tyre pressures up naturally.
