Which Yamaha models and years will this starter fit?

This unit fits a wide range of Yamaha utility and recreational models from the early 2000s. It was engineered to match factory mounting, gear count and rotation, making installation straightforward for compatible machines.

• Grizzly 400/450/660: model years 2002–2010

How does this starter match the original equipment specs?

The starter uses a permanent magnet direct drive (PMDD) design and the same rotational direction and drive gear tooth count as the factory unit to preserve cranking speed and electrical load. That helps avoid draining the battery or creating premature wear on the ring gear.

• 12-volt PMDD construction for consistent torque delivery
• 9-tooth drive gear to mesh with OEM ring gear
• Counter-clockwise rotation matching factory units
• Designed to keep electrical draw within expected factory limits

What parts and compatibility assurances are included?

The package includes the starter motor plus a starter relay so you have the key components needed to address common starting failures. The unit cross-references multiple OEM and aftermarket part numbers for easy verification against your vehicle’s parts list.

• Includes: 1 starter motor and 1 starter relay
• Cross-listed with Yamaha part numbers such as 4WV-81890-00-00 and 4WV-81800-00-00

• Intended to resolve slow crank, no-start, clicking relay, and intermittent starts tied to starter or solenoid failure

How easy is installation and what should I check before buying?

Installation is typically straightforward for anyone familiar with ATV/UTV electrical systems: unbolt the old starter, transfer any required heat shields or brackets, and connect the supplied relay and battery leads. Before purchasing, confirm the year and model of your machine and compare the referenced part numbers to ensure a direct fit.
