Product Description
Standard starters often struggle to turn over engines with increased displacement. The RDLN High Performance Starter Motor is engineered to deliver the cranking torque required for 4-stroke GY6 engines equipped with big-bore kits or long-stroke cranks. Premium copper-wound armatures, an optimized 9-spline gear ratio, and a weather-sealed housing ensure reliable, instant starting even under the extreme cylinder pressure of a high-compression performance build.
- Heavy-duty copper-wound armatures handle higher current loads without overheating
- 9-spline drive precision-machined for smooth starter clutch engagement
- High-compression ready — tuned for 170cc, 180cc, and 232cc big-block GY6 builds
- Weather-sealed housing protects internal magnets from vibration and moisture
- Made in Taiwan
