Crankshaft -BGM ORIGINAL Standard (rotary valve) 48mm stroke, 105mm conrod- Vespa P80X, PX80
Part no.:
BGM031080G
Description
Solid BGM crankshaft for the PX80 models. The PX80 was manufactured for the German market and has a stroke of only 48mm (PX125 = 57mm). The most common damage to PX80 engines is a defective lower connecting rod bearing, usually caused by long idle times or worn connecting rod thrust washers.
The BGM crankshaft has a solid bearing here and also has no problems with the large tuning cylinders (125cc conversion cylinders, DR135, Malossi 139).
As a special feature, the BGM crankshaft has exactly the same intake timing angle as an original Piaggio crankshaft. This makes it the perfect 1:1 replacement for an original crankshaft. Compared to an original crankshaft, the balance factor has been improved and the intake area has been rounded and polished.
Delivery includes the upper connecting rod bearing. Order new crankshaft bearings and shaft seals if required. Installation tools and complete engine overhaul kits for simple and damage-free installation are of course also available in the store.
- Stroke: 48mm
- Piston pin Ø: 15mm
- Connecting rod length: 105mm
Suitable for all PX80 engines (V8X1T/V8X1M)
