Already well known for years, we offer the complete cylinder / piston kit POLINI motori 165cc for 125cc 2-stroke engine CAGIVA MITO, PLANET, RAPTOR, FRECCIA, TAMANACO ... and other models. This POLINI kit offers 34.1hp on FULL ORIGIN motorcycle, a diameter of 64mm (evening a real displacement 162.77cc in combination with the original crankshaft stroke of 50.6mm) and a power speed of 10500 revolutions.
The couple 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 forms of lights, POLINI also re-studied the system of sweeping as well as valve with the exhaust (guillotine).
We recommend it with a detent exhaust, a carburation of minimum 30mm (flat bushel will be fine). If your engine is very advanced, prepared, or even old, we will recommend changing the crankshaft, by the way do not hesitate to ask a reinforced connecting rod kit. A set of rigid slats of carbon valves will be welcome in order to exploit good regimes.
You will not be disappointed with your purchase, the performance is very high, the high-quality aluminum offers very good cooling, the high-end treatment offers rock-solid solidity, the piston with high silicon content equipped with two chrome segments ends offer little friction but no loss of compression for excellent torque! Ideal even for riding every day, even for two on the bike, in addition there are always spare parts in case of breakage, wear ...
Optionally we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust light by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement in the piston and bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
