What's a good pressure to have in your tyres?

I havent needed to touch mine, solid.

Was going to check the pressure though.

Thats what the official Yamaha Service manual says:

Cold tire pressure:
Front 0~90kg        DTR   150kPa(1.5kgf/cm2)          DTX   180kPa (1.8kgf/cm2)
Rear 0~90kg         DTR   175kPa (1.75kgf/cm2)       DTX   200kPa (2.0kgf/cm2)
Front 90~178kg    DTR   175kPa (1.75kgf/cm2)       DTX   180kPa (1.8kgf/cm2)
Rear 90~178kg     DTR   200kPa (2.0kgf/cm2)         DTX   200kPa (2.0kgf/cm2)

Off road riding:
DTR and DTX    Front 150kPa (1.5kgf/cm2)
DTR and DTX    Rear 175kPa (1.75kgf/cm2)

Your gonna need this to convert it to PSI.
