When good things get even better, the bgm PRO Lambretta waves are now the bgm PRO Competition waves. The features that have proven themselves have remained, important technical details have been further improved.

    B>Enhanced features are:
  • Ground pressing surfaces for maximum stability of the joint and thus the highest possible torsional resistance
  • Ground and coated crank pin
  • Forged connecting rod with CNC finishing
  • Hardened and ground bearing and oil seal seats
  • Wider choice of stroke and connecting rod combinations than before
  • Quality assurance of each individual crankshaft through 100% testing by ISO and QC certified manufacturer

  • Full cheek shaft for increased pre-compression
  • Forged crank webs
  • Low-vibration engine running thanks to sophisticated balancing with hidden pockets, copper and tungsten counterweights
  • Lubrication of the lower connecting rod bearing via two large lubrication slots
  • Diameter of the crank pin 22 mm


The bgm PRO Competition shafts incorporate a total of 15 years of experience. Three more years of development work and tests have been carried out in the optimisation phase to create a shaft that offers maximum torsional resistance and stability.

In the English BSSO racing series, Team Replay has started the 2018 season with several bgm parts. Among others with the new and revised bgm crankshaft. Replay's rider Darren Conneely finished second in group 4.
