    I used this to replace a MZPartsMiami 40-tooth sprocket and tophat adapter which provided somewhat poor alignment and absolutely abysmal concentricity. The MZParts tophat adapter had a misaligned 6-bolt pattern which caused the chain to get too tight/too slack during rotation and the teeth of that sprocket would bite the chain rollers, causing it to pop.

    This sprocket solved all issues. It mounts perfectly to HY-22 mag wheels – perfect chain alignment to the engine, fantastic concentricity that provides even chain tension throughout rotation and eliminated my need for a tensioner/idler pulley, and the teeth are perfectly machined to grip the chain without slippage or biting into the chain rollers.

    Worth every cent.
