HI THERE

25PSI FRONT
29PSI REAR

easy peasy japanesy

although it sounds a wee bit low

Maybe, but it is a very light bike which would not get a lot of sidewall flex at higher pressures.

what exactly is sidewall flex, is it good or bad?
scuse my noobness

Yeah, that's what it says in the RGV and FXR manuals.

Depends on the tyres, though. When I put MT75s on my FXR, the guys at Leading Edge told me to run 36/32, and that worked real nice.

If you still have the filthy awful stock tyres on that thing (are they as bad as the FXR's?) get some real ones on pronto.

Actually, the whole tyre should flex (ever so slightly). This allows the tyre to heat up which improves grip also keeps a greater amount of tread area touching the road. Too hard - the contact area is reduced & tyre runs cool. Too soft - the tread (stipes??) close up & tyre gets too hot. You need to experiment a bit to find the best allround pressure for your bike. The bike will 'feel right'. Bear in mind tho that you are looking for a compromise that covers your riding style & dry/wet conditions. Measure tyre pressure cold. I'd say make alterations of 2psi at a time. Also, as jrandom says, the tyre make/model will be a VERY important part of performance.

Im pretty sure they are stock standard. bloddy thing, practially push bike tires.
can I actually fit those fatties I see on other bikes to mine? I assumes it would only take that one gauge of tire.

I think a bit of playing around this weekend is in order. hopefully its going to be nice weather
