MALOSSI 290c cylinder / piston kit for YAMAHA MAJESTY, X MAX, MBK SKYLINER, APRILIA LEONARDO ... BUGGY 250, 260 and 300

High performance MALOSSI kit increasing the displacement and compression of your YP 250/260 and 300 engine. 300 is a trade name, for example, the APRILIA LEONARDO 300 is really only 264cc with its 71mm diameter piston! This kit with its diameter of 74mm gives the actual displacement of 287.29cc with the original stroke of 66.8mm! This kit with its aluminum cylinder with nicasil coating of very high quality and a revised cooling architecture, offers great robustness over time! the very high quality piston offers less friction to release power and revs, moreover, it offers more compression to improve the ratio in combination with the original cylinder head! We recommend this kit with a carburetor adjustment (or injection box on injection models), a sport variator and ideally a sport exhaust line. A preparation of the original airbox and / or a sports air filter can be a real plus to let the beast breathe.

* Piston pin Ø17mm
