Vespa PX200 Rally 200 T5 Cosa LML 2T BGM Pro Gear Cluster 12-13-17-20

BGM PRO auxiliary shaft for Vespa Largeframe PX, Rally, T5, Cosa, LML (2-stroke)

Maximum stability with best performance by ideal graduations

Modern cylinders like Malossi MHR, Quattrini M244 or Pinasco 251 have raised the power and torque level of the Vespa Largeframe engines to a completely new level.
The transmission components used must be correspondingly stable.

MATERIAL QUALITY
The BGM PRO auxiliary shafts are made of high-quality 21NiCrMo2 (1.6523) case-hardened steel whose surface is finally hardened and tempered to 62HRC. The high core strength of the material (900N/mm²) allows a maximum load transmission (high motor torque), the very good toughness (ductility) a very high resistance to load peaks. The final heat treatment hardens the surface to a depth of 0.6-0.8mm resulting in maximum wear protection.
