Soarider Starter Motor & Solenoid Relay for Honda TRX300/TRX300FW (1988–2000) — 12V CCW 10‑Tooth Direct-Fit Kit

If your FourTrax won’t spin over or the starter has become intermittent, this Soarider kit gives you a practical replacement engineered to match OEM fitment for many late-1980s and 1990s Honda ATVs. The package includes the starter motor plus the starter solenoid relay and is specified to the same electrical and mechanical parameters as common factory parts, so installation is straightforward for anyone familiar with basic ATV maintenance. Verify your exact model and part number before ordering; this kit does not fit the TRX300EX model.

Will this starter work on my Honda TRX300 or TRX300FW?

This Soarider assembly is made to replace original starters on TRX300 FourTrax 2x4 (1988–2000) and TRX300FW FourTrax 4x4 (1988–2000), plus select TRX250 and ATC models from 1987. Confirm your motorcycle’s year and original part number against the listed replacements to ensure compatibility.

• Also fits: TRX250 Fourtrax 1987, ATC250ES and ATC250SX 1987

What are the electrical and physical specifications I should know?

The starter motor is a 12-volt PMDD (permanent magnet direct drive) unit with counterclockwise rotation and a 10-tooth pinion, matching the mechanical engagement and electrical requirements of the specified Hondas. These specs are important for correct gear mesh and starter engagement.

• Voltage: 12V for standard ATV electrical systems
• Rotation: CCW (counterclockwise)
• Teeth: 10-tooth pinion for proper ring gear mesh
• Starter type: PMDD — compact, direct-drive design

What comes in the box and what should I prepare for installation?

The kit ships with one starter motor and one starter solenoid relay — everything you need to replace the common failed components in the starting circuit, though basic hand tools and safe battery handling are required. Remove the old starter and relay, compare mounting points and electrical terminals, then install per your service manual torque specs.

• Included: 1x starter motor, 1x starter solenoid relay
• Tools recommended: socket set, wrenches, battery terminal puller, torque wrench
• Installation tip: disconnect battery ground before removing old starter
• Verify fit: match part numbers (e.g., 31200-HA6-306, 31200-HC4-033) before fitting

Who this product is for: This Soarider starter and relay kit is aimed at DIY mechanics, ATV owners, and small repair shops restoring or maintaining older Honda FourTrax and ATC models from the late 1980s through 2000. It’s ideal for anyone needing a direct-replacement starter with OEM-compatible specs (12V, CCW, 10 teeth, PMDD) to bring a non-starting or unreliable engine back to dependable operation. Always check compatibility with your vehicle’s year and original part number prior to purchase to ensure a correct fit.
