Product Description
Knobtown Cycle brings you the CYCLE ELECTRIC INC REGULATOR 09-13FL W/OC, built for riders who demand quality and reliability.
Key Features
- Control voltage on Harley-Davidson and Buell alternators, unlike other rectifiers or regulators that dump to ground and cause maximum stator current and higher temperatures
- Cycle Electric rectifying regulators block current to control voltage; this reduces stator current, resulting in low temperature and less drag on the motor, which means more efficient operation
- Made in the U.S.A.
- With low-mount oil cooler
