Reinforced “Life-Time” Starter Clutch

One of the most frequent failure points in V-Twin starters is the clutch mechanism spinning out or failing to engage. The Protorque assembly features a heavy-duty, oversized starter clutch designed to withstand the violent kick-back often associated with high-displacement engines. By utilizing reinforced rollers and high-tension springs, this starter ensures positive engagement with the ring gear every time you hit the button, eliminating the frustrating “whirring” sound of a failed unit.

Advanced Gear Reduction and Efficiency

The Protorque 1.4 kW motor utilizes precision gear reduction technology to multiply rotational force while maintaining a low amperage draw. This efficiency is critical because it leaves more battery energy available for your ignition system to produce a hotter spark during the cranking cycle. The result is an engine that reaches its firing RPM faster, leading to quicker starts and less wear on your battery and charging system.

Professional-Grade Construction

Every Protorque starter is built to professional standards. The armature hairpins are resistance-fused to the commutator rather than soldered, ensuring the electrical connections remain stable even when the motor is subjected to the high heat of a summer traffic jam. Each unit is fully dyno-tested before leaving the factory and includes a performance test curve sheet, guaranteeing that your starter meets its advertised 1.4 kilowatt power rating out of the box.
