im using both azusa rear tire drum, and just installed a clutch brake
the drum on my 212cc barely stops it and in an emergency it wont help
but the clutch brake is super strong, too strong
but at least it will stop the bike, use both and its normal stopping power
i just made the clutch brake weaker because if you adjust like normal brakes it instantly locks the rear tire on the streets
i made this bracket for my engine
