Protorque 1.4 Kw High Torque Starter For Harley Sportster / Buell 1981-2022
Protorque 1.4 kW: High-Torque Starting Power for Sportsters and Buells
The Protorque 1.4 kW High-Torque Starter is engineered for the Harley-Davidson Sportster enthusiast who demands more reliability than the factory unit can offer. Whether you are running a high-compression 1250cc big-bore kit or a stock 883cc engine that struggles during hot restarts, this 1.4 kilowatt powerhouse provides the mechanical muscle to get your V-Twin spinning. It is a direct-fit solution that brings modern electrical efficiency to a wide range of Sportster and Buell applications.
Superior Cranking Torque for Evolution and Ironhead Engines
Factory starters are often the “weak link” in a Sportster’s electrical system, especially when heat-soak occurs. The Protorque unit utilizes an advanced gear reduction system to multiply rotational force, delivering up to 50% more torque than stock. This allows the motor to overcome the resistance of high-lift cams and increased cylinder pressure, ensuring that your engine reaches the required firing RPM faster while putting less strain on your battery.
Heavy-Duty “Life-Time” Starter Clutch
One of the primary causes of starter failure in V-Twins is the starter clutch “spinning out.” Protorque addresses this with a reinforced starter clutch featuring oversized rollers and high-tension springs. This ensures positive engagement with the ring gear every time you hit the start button, eliminating the metallic “clunk” or “whirring” associated with a failing OEM clutch.
Built for Extreme Reliability
Every Protorque starter is constructed with industrial-grade internal components, including sealed ball bearings and heavy-duty armatures that are resistance-fused to the commutator. This high-heat construction prevents the electrical connections from melting during difficult starts. Each unit is fully dyno-tested to ensure it meets its power rating and includes a performance test curve sheet as a guarantee of quality.
