ENGINE AND DRIVE SYSTEMS

Your rear wheels will track the front
wheels, with limitations on speed and turning
percentage. This is completely variable, so if
you accelerate in a turn, your match on the
rear will slowly come out. This feature keeps
the machine safe when turning.
NOTE: If you want to match all the time,
decrease your speed or make a less
drastic turn.
