!Not to use on public road, only track use.

Most performant exhaust for your Aprilia RS 125.  Works best on big bores 140 or 156 cc or tuned 125 cc engines.  Best results with modification of your standard carb to 34 mm carb and free flowing air filter.   Match made in heaven for the Italkit 140 cc.  Comes with flange rings and tail rings to fine tune its performance.
