Details

Solid BGM crankshaft for the PX80 models. The PX80 was manufactured for the German market and has only 48mm stroke (PX125 = 57mm). The most common damage to the PX80 engines is a defective lower conrod bearing, usually caused by long service life or worn conrod thrust washers.

The BGM crankshaft has a solid bearing here and has no problems even with the large tuning cylinders (125cc conversion cylinder, DR135, Malossi 139).

As a special feature the BGM crankshaft has exactly the same intake control angle as an original Piaggio crankshaft. So it is perfect as a 1:1 replacement for an original crankshaft. Compared to an original crankshaft, the balance factor has been improved and the intake area rounded and polished.

The delivery includes the upper conrod bearing. New crankshaft bearings and shaft sealing rings can be ordered if required. Installation tools as well as complete engine revision kits for easy and damage-free installation are of course also available in the shop.

Stroke: 48mm

Piston pin Ã: 15mm
Connecting rod length: 105mm

Fits all PX80 engines (V8X1T/V8X1M)
