Hi, i need to know what the recomended tire pressure is for a 1998 rm 125 with a 155pound rider???, i mostly trail ride and was wondering???, also, do i need to deflate my tire while using a fork support when tied down???
You can start at 15 psi which is common to dirt bikes. You can try less air if it helps traction but don't go too low(under 10) or you can pinch the tube easily.
No need to deflate the tire when using a fork support.
