as of right now everything is stock they didnt work well when i got it and i remember seeing somewhere where the x would do stoppie's a friend of mine has a 25 his locks up like no other but make sure they're not glazed over or anything first thanx for info
ive had the x since it came a few years ago the brakes never have been great what can i do to make them better i have tightned up the screw on the end of the throttle rod that seemed to help a lil but after the batteries start to get weak they start to fade bad
