Cylinder BRK Racing 144cc Aprilia RS engine Rotax 122/123 2T

Cylinder oversized from the manufacturer BRK for the ROTAX 122 engines of Aprilia RS 125cc.

This cylinder transforms the 125cc model into a 144cc. In these engines, which are already very powerful, this change is spectacular. You will achieve a much fuller engine at low revs, greater response at mid-range, and a slightly higher top speed.

It comes equipped with a two-ring piston, from the manufacturer BRK, with a 58mm diameter.

It must be installed with the original cylinder head.

Attention: When installing this cylinder, it is very important to make the corresponding carburetion adjustment, as these models are very sensitive and delicate to excessively lean carburetion.
