bgm PRO - THE VESPA COUPLING
The bgm PRO - couplings for Vespa, and also those for Lambretta, are among our top sellers!
The couplings are available complete and in various designs as well as all parts individually.
The latest components for Vespa Largeframe, are now the Clutch pinion for the 67 and 68 primary gear.
Developed for enormous power and torque
The bgm PRO couplings were designed for the enormous powers and torques of today's engines. They are made from high-alloy steel (SCM415 / 15 CrMo 5) according to the highest manufacturing standards. The extremely high strength of the base material (up to 1100N / mm2, HRC 58-62) provides a reassuringly secure basis for the production of BGM pinions.
Manufacturing at the highest level
The production meets the high standard for transmission production by Honda. Each individual part receives a test report. BGM thus has a permanent quality assurance.
- High quality material 15 CrMo 5
- Precise production according to Honda standards
- Continuous quality control
- Can be used on COSA2 coupling types
- Available with 20,21,22, 23, 23 and XNUMXT (XNUMXT = special pinion)
- Suitable for the original primary of all 80-150ccm engines, as well as all Cosa models
- Suitable for engines with retrofitted 67/68 tooth primary gear
A characteristic feature of the BGM pinion is its black color and the practical labeling stating the number of teeth the pinion itself has and which primary gear it is suitable for.
Longer translation without disassembling the engine?
The pinion with 23 teeth is particularly interesting. This was never original from the factory.
It is intended to extend the reduction of the 80-150ccm as much as possible. A 23/67 or 23/68 gear ratio can be used without opening the engine. Ideal for all drivers of large-capacity cylinders on, for example, original PX125 or Sprint 150 engines.It even fits into the Vespa Cosa models, as here, without exception, a (too short) reduction ratio of 21/68 was installed ex works.
Every PX125 driver who wants to drive a 177cc cylinder can install a suitably long gear ratio simply by exchanging the clutch. The reduction is extended by a whopping 15%, which corresponds roughly to the same increase in the top speed in km / h.
BGM clutch pinions are the perfect complement to the indestructible BGM Superstrong clutch.
All BGM Superstrong clutches with 20, 21, 22 and 23 teeth are equipped with this pinion ex works. It can be combined with all Cosa2 coupling types (recognizable by at least 8 spring positions).
