Soarider Starter & Relay for Honda Rancher 420, Foreman 500 & Pioneer 500 — 12V PMDD CCW, 9‑Tooth OEM Fit (2007–2021)

Soarider's all-in-one starter motor and starter relay replace worn or damaged units on compatible Honda Rancher, Foreman and Pioneer models, restoring reliable engine cranking with a 12V PMDD design and CCW rotation.

This replacement kit includes a 12-volt permanent magnet direct drive (PMDD) starter motor and a matching starter relay engineered to fit specific Honda ATV and UTV applications. Built to match OE mounting, electrical connections, and tooth count, the assembly offers a cost-effective aftermarket alternative to part numbers such as 31200-HP5-601 and 31200-HR0-F01. Before ordering, confirm your vehicle model year and sub-model to ensure compatibility.

Will this starter fit my Honda Rancher 420 or Foreman 500?

Compatibility depends on exact model and production year. The Soarider starter is made for Rancher 420 TRX420 series from 2007–2019 and many Foreman 500 TRX500 models from 2012–2019, but some sub-models require a different option—so always cross-check part numbers and model notes.

• Fits Rancher 420 TRX420FA/FE/FM/TE/TM and related TRX420FPA/FPE/FPM variants listed for 2007–2019.
• Fits Foreman 500 TRX500FE/FM/FPE/FPM series for 2012–2019; earlier TRX500 years may need Model 1 or Model 2 alternatives.
• Also compatible with Pioneer 500 SXS500M series (2015–2021).
• Not for some TRX500FA/TRX500FPA 2012–2014 sub-models—verify before purchase.

What are the technical specs and how do they match OEM parts?

The starter motor is a 12V unit with counterclockwise (CCW) rotation, 9 teeth on the pinion gear, and a PMDD configuration that mirrors common OE characteristics. The kit ships with a dedicated starter relay to reproduce the original electrical switching behavior and make installation straightforward.

• Voltage: 12 volts; Rotation: CCW; Teeth: 9 on the pinion gear.
• Starter Type: Permanent Magnet Direct Drive (PMDD) for compact size and fitment.
• Includes both starter motor and starter relay for a complete swap.

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

• Disconnect battery negative first; remove old starter and compare electrical plugs and mounting points.
• Verify the 9-tooth pinion and CCW rotation match your OEM unit.
• Transfer any heat shields or brackets as needed; tighten bolts to factory torque specifications.
• Reconnect battery and test cranking before reassembling panels.
