APRILIA RS 125 ROTAX 122 PORTED CYLINDER / BARREL? More Power Than Polini

Not sure who ported it however a friend used this and it made much more power than a polini 154 kit he previously had fitted. It's a really nice cylinder. They have opened up most ports and matched them to the cases. THIS/ THESE PARTS MAY FIT OTHER MODELS PLEASE FEEL FREE TO ASK IF YOU ARE UNSURE.
