Crankshaft -PIAGGIO (rotary valve)- Vespa PX125, PX150
Part no.:
7671572
Description
Original Piaggio PX 125/150 crankshaft in the usual good quality at an unbeatable price. As a replacement for a worn out crankshaft in a touring engine, or to finally get a PX 80 engine up to 125ccm (cylinder base has to be adjusted), also needed to convert late Sprint, t.s.125 and gtr models to 12Volt PX electrics. Also indispensable to "upgrade" a PX 80 with a 177 DR cylinder for moderate tuning. Due to the thick crankshaft stub, this standard crankshaft is almost indestructible and proven a million times over.
