SIP PERFORMANCE crankshaft for Vespa 150 GS with PX type clutches.

High end racing crankshaft. These crankshafts have been produced to open the door for people with Vintage Vespas to the tuning world. These are the peak in performance crankshafts, second to none. The conrod has been polished to reduce turbulence in the crank casings. A needle roller bearing replaces the bronze bush, allowing for higher engine speeds and reduced oil requirements.

This crankshaft has the clutch side stub the same as a Vespa PX so you would need to fit a PX/T5/COSA type clutch with this crank.

Specs:
Stroke: 57mm
Rod length: 105mm
Cone: flywheel side
PX clutch stub: clutch side
Pin: 15mm
