High Torque Starter Motor for 125cc and 150cc GY6 Engines
The OKO High Torque Starter Motor is designed for reliable ignition in modified GY6 engines. This starter is particularly effective for 125cc and 150cc models that utilize performance upgrades like Big Bore Kits or Stroker cranks. It is one of the key GY6 scooter parts for those needing extra cranking power to ensure consistent starts, even under high compression conditions.
High-Torque Design
This starter motor is built to provide increased rotational torque, addressing the challenges posed by high-compression engines. Unlike standard starters, this unit minimizes battery strain and prevents the common "solenoid click" issue associated with powerful builds. Its heavy-duty construction includes reinforced internal components to withstand extended cranking periods.
Durability Features
The motor includes a 9-spline heavy-duty shaft and a weather-sealed housing, ensuring reliable performance in various riding conditions. The design reduces wear and tear, thus improving reliability over time. Riders can expect improved cold starts thanks to faster cranking speeds from this starter.
