CM705-(001/002-)-460-(B/Raw) | Installation Instructions for Ducati Scrambler Rear Sprocket

David Bumpus posted this on Jul 5, 2016

Upgrading the rear sprocket on your Ducati Scrambler won't only dramatically change the way the bike looks, but will help improve the amount of torque being transferred to the rear wheel. Installing the rear sprocket itself is fairly simple, but you have to replace your chain whenever you install a new rear sprocket. If you're unfamiliar with how to install a new chain, we highly recommend taking your bike to a licensed mechanic to have them do it for you. To further improve your bike's looks and performance, we suggest upgrading your front sprocket and exhaust at the same time as the rear sprocket.
