Already well known for years, we offer the POLINI motori 154cc complete cylinder / piston / cylinder head kit for ROTAX 122 and 123 engines, the engine that equips 125cc 2-stroke models such as the APRILIA RS, AF1, EUROPA, PEGASO, TUAREG RALLY / WIND, RED ROSE, 125cc and other models.
The kit is announced by POLINI has a power of 37hp at 11,000rpm. Couple level one thing to say according to our customers .... It's hard! It has a reputation for being more solid than els GILARDONI. It can be fitted with the electric and pneumatic exhaust valve!
The torque will also be greatly increased! The machine will be more flexible and the power more exploitable. Please note that road use is prohibited. This room is reserved for the circuit. To increase the power, POLINI worked on the diameter of the piston (by simple increase), but also on the diagrams, the shapes of lights, POLINI also re-studied the scanning system. The cylinder head is also corrected on the chamber volume side for a better compression ratio and shape.
We recommend it with a relaxation exhaust, unbridled ignition, a minimum carburation of 30mm (round bushel will be fine). If your engine is very driven, prepared, or even old, we will recommend changing the crankshaft, in passing do not hesitate to install a reinforced connecting rod kit. A set of rigid carbon valve slats will be welcome in order to exploit good speeds .

As an option we offer you a stage 1 preparation, this preparation is a modification of the rear side channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. A correction of the faulty passage of the coolant is also made! POLINI kits are known to heat, the two passages are therefore improved! Allow a little extra time for this preparation!
