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.

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.
