This starter solenoid relay is a high-grade aftermarket spare part, tailor-made for the Yamaha Moto-4 350 (YFM350) ATV models built between 1987 and 1995.
It acts as the core power control unit of the starting system, supplying 12V voltage to the starter motor to achieve smooth engine turnover.
Made with a heavy-duty fully sealed outer casing and premium internal hardware, it reliably fends off dampness, grime, high temperatures and constant vibration brought by off-road riding.
It fixes frequent startup faults including intermittent cranking, abnormal clicking sounds and complete no-start failures, being a long-lasting and budget-friendly replacement for ATV servicing.
