JINGKE 3-Bolt Electric Starter Motor for 50cc–125cc 4-Stroke ATVs & Go-Karts — 12-Tooth Clockwise, Includes Mounting Hardware

JINGKE's 3-bolt electric starter motor replaces worn starters on 50cc–125cc 4-stroke ATVs, go-karts, pit bikes and small dune buggies for reliable electric starting.

This compact starter motor is engineered to fit many common small-engine platforms — including Taotao, SSR, Roketa, Jonway, SunL, Coolster and similar makes — using a 3-bolt mounting pattern and a 12-tooth clockwise gear. It’s a direct-replacement style meant to simplify repairs when your factory starter has failed or become unreliable, and it ships with the basic hardware needed for installation.

Will this starter fit my 50cc–125cc ATV or pit bike?

The JINGKE starter is built for broad compatibility across many 4-stroke small-engine vehicles that use a 3-bolt starter layout. Measure your existing starter’s bolt hole spacing and confirm gear orientation to ensure a match.

• Bolt hole A spacing: 2.85 inches; Bolt hole B spacing: 3.16 inches.
• Gear: 12 teeth, clockwise rotation — verify your machine uses the same orientation.
• Common compatible brands: Taotao, SSR, Roketa, Jonway, SunL, Coolster and many sandrail/go-kart models.

How straightforward is installation for a home mechanic?

Installation is intentionally simple for anyone comfortable with basic small-engine work. The three-bolt design and included screws let you mount the unit quickly; typical installs require basic hand tools and about 20–45 minutes depending on access.

• Includes installation screws and a spark plug for convenience.
• Designed to align with standard starter mounting patterns on compatible models.
• Disconnect the battery and follow vehicle-specific service steps to avoid damage.

What materials and durability features should I expect?

This starter uses quality components intended to withstand frequent cranking and off-road conditions. It’s factory-tested for performance and built to resist wear common in rough-terrain applications, though real-world life will depend on use and maintenance.

• Engineered housing and internal components for extended service life.
• Sealing and finishes chosen to tolerate dirt and vibration from ATVs and buggies.
• Designed for routine replacement cycles typical of small-engine vehicles.

How can I confirm compatibility before buying?

Always compare the starter’s physical measurements and gear specs with your current part. Check the provided images for mounting orientation and confirm electrical connections match your vehicle’s wiring harness.

• Compare bolt spacing (2.85" and 3.16") to your existing starter mount.
• Verify the 12-tooth, clockwise gear meshes with your flywheel ring gear.
• Contact the seller with photos if you’re unsure — they can help confirm fit.
