Kit 252cc MASTER pinasco 26360021 Valve for Vespa PX 200 252cc Cylinder Kit + Dedicated Crankshaft

252cc Thermal Group Kit for Vespa PX 200 26360021 252cc MASTER Kit (Valve) for Vespa PX 200 (252cc Thermal Group + Dedicated Crankshaft). 252cc thermal group kit for all 200cc engines for Vespa PX for a perfect "plug and play" assembly. The 252cc displacement was obtained using a 72mm piston and a special 60mm stroke crankshaft with 130mm connecting rod, eliminating the "collar" of the cylinder liner, so it will not be necessary to bore the crankcase for assembly. The performance is remarkable, but what is impressive is the torque developed by the engine and the total absence of vibrations, a kit created for touring use that does not require particular technical knowledge for assembly. The thermal group can be used with admission to the crankcase or to the cylinder.
