This is not a motorcycle forum, it does not use motorcycle standards and comparison is broadly irrelevant and confusing. For 140 years pedal cycles and motorcycles have evolved along divergent paths, the terms and technology are different. There are motorcyclists here, but they use pedal cycle terms and discuss pedal cycle technology because that's the forum's purpose. If you want a "bicycles for motorcycle mechanics" forum I suggest you start one on Facebook. OTOH if you want to discuss bicycles please use the appropriate terminology and try to keep the discussion on-topic.
