I've been thinking about this a little bit - at least according to parts being sold on ebay both the clutch sprocket and front driveshaft drive sprocket are 41 tooth (connected by a larger sprocket in the middle). I wonder why they would overdrive it by design and how it would be compensated for in ABS/traction control at a vehicle level (and also have the strict requirements for tire diameter variation). Is there some hydraulic-force overdriving?
