About this collection
Drivetrain
The drivetrain is where power becomes drive — and where gearing turns a bike from nervous to perfect. Chains, sprockets, carriers and drivetrain accessories from EK Chain, LighTech, Sitta, K-Bike and Puig, from race-spec 520 conversions to direct road replacements.
Gearing is the cheapest performance modification in motorcycling: one tooth less on the front or two more on the rear transforms drive out of corners. Change chain and sprockets as a set — a worn chain eats new sprockets and vice versa — and match pitch, tooth count and fitment to your exact model.
