Pitpro 140 xr is a brilliant bike,I weigh about 95kgs and I have owned mine for about 2 months now.I am now at a point where i'm hitting my ramp with 8M gap all day long and nothing has broken or fallen off it yet,doesnt bottom out at all with my weight when jumping.
I have trail ridden it all day on sunday and no problems at all,even had some guys with 400's/450's pretty impressed with what it could do.
For the price of $1195 from Maylands performance if your in SA,it is top value coz it has IRK,Kenda tyres,fastace rear shock,longer travel USD fork(which seems to work relly well)all fitted as standard and hammers so only mod really needed is a set of pro tapers.Until things start to wear out they probably dont need upgrading coz they all do the job well.
