IF you change your risers make sure to double check the cable holders on the handle bars - don't know the official name but they look like black zip ties that hole the cables to the handle bars on each side. The locking portion of the zip tie typically faces the rider and should be rotated 180* away from the rider after changing risers. If not, when turning the wheel from full left to full right turns MAY result in the locking portion of the zip tie to touch or even dent the gas tank. Don't ask me how I know this!!

NOT saying this is true of ALL riser changes - just providing an alert for you to double and triple check for adequate clearance between the gas tank and locking portion of the zip tie BEFORE you finalize the riser change. Just sayin'
Good luck !
