Cylinder d.57mm Italkit Sport 140cc Aprilia RS 125cc (engine 122)

Cylinder Kit d.57mm Italkit Sport 140cc Aprilia RS 125cc (engine 122), excellent value for money tuning cylinder for 125cc supermotos with Rotax 122 engine (Aprilia RS 125cc etc.). The cylinder kit includes:

• aluminium cylinder with boost port supported exhaust
• Vertex Piston with 2 rings d.57mm

More displacement always means more power so raising displacement from 125cc to 140cc will naturally get you a nice increase in performance; this is the version with 2-ring piston, for even more power check the racing kit with 1-ring piston. You don’t really have to change any other components to notice the improvement, simply install the new cylinder and go. The cylinder is compatible with Rotax 122 – 123 2-stroke 125cc engines which is used in many different models. Here are some examples:

• Aprilia: AF1 Futura, AF1 Replica, AF1 Sintesi, Europa, MX, Pegaso, Red Rose (with Rotax 122-123 engine), RS, RS Extrema, RX, Sport, SX, Tuareg Rally and Tuareg Wind.
• HM: Dérapage and CRE 125cc
