Cosa Clutch Drive gear 20 tooth BGM

BGM coupling pinions are bullet proof. Developed for the enormous power and torque of today's engines, they are made of a high-alloy steel (SCM415 / 15 CrMo 5) to the highest manufacturing standards. The enormously high strength of the base material (up to 1100N/mm2, HRC 58-62) provides a reassuringly safe basis for the production of BGM pinions.

The production meets the high standard of Honda's gearbox production. Every single part receives a test report. BGM thus has a permanent continuous quality assurance.

Characteristic feature of the BGM sprockets is their black colouring as well as the practical inscription indicating the number of teeth the sprocket itself has and for which primary gear it is suitable.
