With over 15 years of experience and three more years of dedicated development, this crank delivers exceptional stability – even with longer stroke and conrod – making it the perfect match for performance-tuned Lambretta engines.
Recommended by Mark Broadhurst, MB Scooters, February 2025:
“Today we have purpose made full circle cranks that are full circle made from solid metal, with various balancing pieces pressed in place to keep the higher compression and try to get a better smoother balance. (…) BGM got it right, they were super tight, so tight they take 15 tons to press together, moving them is very difficult and it is full circle and balanced very well – these are our go to crank – when available!”
