Warp 9 Warp Drive

A conversion that replaces the belt primary drive with a 420 chain. It includes two dampened sprockets in EDM coated black steel and a KMC 420 O-ring chain at 42 links with a master clip, and the final drive ratio is the same as the belt it replaces, so gearing does not change.

Chain drive is louder than a belt, but Warp 9 rates this kit at 10 to 15 decibels quieter than other aftermarket 420 chain drive kits, which is the difference the dampened sprockets make. The replacement chain and both sprockets are sold separately as service parts. Check chain tension after the first few rides while everything beds in.
