People upgrade these for variable speed? or something else?
If your unit has a single-speed throttle, you could try replacing it with a variable speed throttle. Generally though, this bundle is purchased to replace a faulty component and ensure compatibility between the throttle and control module. To determine which control module + throttle bundle would be compatible with your unit, please give us a call at 1-800-798-0325 or email us at contact@monsterscooterparts.com to provide the unit's Product ID number.
