RDLN High Torque Starter Motor GY6 150-232cc Performance

Standard starters often struggle to turn over engines with increased displacement. The RDLN High Performance Starter Motor is specifically engineered to deliver the massive cranking torque required for 4-stroke GY6 engines equipped with big-bore kits or long-stroke cranks. Higher rotational force and improved thermal efficiency ensure reliable, instant starting even under the extreme cylinder pressure of a high-compression performance build. Key Features Heavy-Duty Internal Windings: Premium copper-wound armatures handle higher current loads without overheating during extended cranking Optimized Gear Ratio: 9-spline drive precision-machined for smooth starter clutch engagement, reducing mechanical drag and wear High-Compression Ready: Tuned to overcome resistance of 170cc, 180cc, and 232cc "Big Block" GY6 configurations Weather-Sealed Housing: Reinforced casing protects internal magnets from vibration and road moisture Technical Specifications Bolt Hole Spacing: 78mm Shaft Length: 22.5mm Number of Splines: 9 Diameter (at O-ring): 30mm Shaft Diameter: 11.5mm Overall Dimensions: 6.5" L x 5.5" W x 4" H Distributor SKUs: Parts for Scooters 155-4 / 169-282 Compatibility Engine Family Compatible Builds GY6 150cc (157QMJ) Standard, big bore (58.5mm+), and stroker builds GY6 125cc (152QMI) Performance-tuned 125cc variants Polaris / Kymco / SYM Select 150cc models using GY6 engine architecture Mechanic's Note: A high-performance starter is only as good as the power it receives. We highly recommend pairing this with a Performance Starter Clutch and ensuring your battery has at least 200+ Cold Cranking Amps (CCA). Always inspect your starter bendix for debris before installation to prevent gear binding. California Prop 65 Warning: www.p65warnings.ca.gov Made in Taiwan
