BGM1770PP635 Piston -BGM PRO- Vespa PX125, PX150, Sprint Veloce – conversion piston for Polini177 (cast iron) cylinder –


Product Description

Reinforced BGM piston with Ø63,0mm for Polini 177 and DR 177cc tuning cylinder (suitable for Vespa PX125/PX150 and Sprint Veloce engines). Diameter Ø= 62,93mm (suitable for cylinders with original bore Ø=63,0mm) Recommended running clearance: 7/100mm Silicon content of 18% for increased wear and tear and scuff resistance piston rings 1mm thickness optimized passage in overcurrent range The BGM PRO piston has 18% silicon content. This means that it has less thermal expansion than the pistons normally used in tuning cylinders. This makes the piston not only more wear resistant but also thermally much more stable. In addition, the piston has two very stable piston rings with a thickness of 1 mm. This increases performance through reduced friction and eliminates the susceptibility to breakage due to the material used for the piston rings. The stable piston rings allow a wider outlet window without the risk of ring breakage. The generously recessed area in the overcurrent area helps the engine to process more mixture. In combination with the thinner rings and the shorter piston shirt, the engine becomes much more agile and durable. Compression height: 35mm (original Polini / DR 35mm) TIP: Also available as oversize piston with 63,5mm. The cylinder must then be drilled to size and honed by a specialist company. This allows damaged cylinders (clamps, seizures) to be repaired.(DL_DE)
