This starter solenoid relay is a premium aftermarket replacement built for Yamaha Tri-Moto 225 YTM225 ATV models from 1983 to 1986. It serves as the core power control part of the starting system, transferring stable 12V power from the battery to the starter motor for smooth engine ignition.

Adopting heavy-duty fully sealed housing and high-quality internal components, it effectively resists dust, moisture, mud and strong off-road vibration. It fixes common starting problems including intermittent cranking, clicking sound and startup failure, making it a cost-effective replacement for daily ATV maintenance.
