STABSOLI Starter Motor Kit 3-Bolt 12-Tooth for 50–125cc ATVs & Dirt Bikes — Includes Solenoid & CDI

STABSOLI's 3-bolt starter motor kit combines a 12-tooth clockwise starter, a matching solenoid relay and a CDI into a single replacement kit for 50–125cc Chinese ATVs, dirt bikes, pit bikes and go-karts.

This complete starter assembly replaces worn or broken starting components on a wide range of small-displacement off-road vehicles. The kit includes the starter motor, solenoid relay, CDI unit, three mounting screws and an angled wrench designed to reach fasteners in tight engine bays. Built to fit many popular Chinese-brand quads and minibikes, it’s a practical way to restore electric start function without sourcing parts separately.

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

The STABSOLI kit is made for many 50–125cc Chinese-engine small vehicles that use a 3-bolt, clockwise (CW) 12-tooth starter. Check bolt-hole spacing and rotation direction to confirm compatibility before ordering. If your bike or quad lists a 3-bolt starter with similar measurements, this kit is likely a match.

• Starter teeth: 12-tooth gear, clockwise rotation
• Bolt hole A spacing: 2.85 inches; Bolt hole B spacing: 3.16 inches
• Commonly compatible makes: SSR, Roketa, Taotao, Jonway, Coolster, SunL and similar Chinese models
• Suitable for engine sizes: 50cc, 70cc, 90cc, 100cc, 110cc, 125cc

How easy is it to install the kit myself?

Installation is straightforward for anyone comfortable with basic mechanical work and electrical connections. The kit supplies the required screws and an angled wrench that simplifies access in cramped mounting locations. Follow standard safety steps: disconnect the battery, compare mount points, then bolt the starter in place and connect the solenoid and CDI per your vehicle wiring.

• Includes 3 mounting screws and a specially angled wrench for tight clearances
• Replace in-place: no need to modify engine casings or adaptors
• Simple wiring: plug or terminal connections to existing battery and ignition harness

What performance and durability can I expect?

STABSOLI supplies this kit as a higher-quality replacement option versus worn factory parts, aiming for reliable starts and longer service life. The motor and solenoid are built to handle routine starting cycles for recreational off-road use. As with any replacement component, correct installation and proper electrical connections help maximize longevity.

• Designed for regular off-road use on small-displacement vehicles
• Corrosion-resistant finishes on external parts for outdoor exposure
• CDI included to ensure compatible ignition timing and starting control

What comes in the package and what should I check after installation?

The kit arrives complete with everything needed to swap in a new starter system. After fitting, test cranking while the vehicle is in neutral and ensure the solenoid engages cleanly and the starter pinion meshes without grinding. Confirm all wiring is secure and battery voltage is sufficient for reliable engagement.

• Package contents: starter motor, starter solenoid relay, CDI unit, 3 screws, angled wrench
• Post-install checks: secure fasteners, correct wiring, clean gear engagement
• If fitment questions arise, contact the seller for rapid assistance

Who is this for? Riders, mechanics and DIY enthusiasts who own 50–125cc Chinese-style ATVs, pit bikes, go-karts, dune buggies or sandrails that require a direct-replacement 3-bolt starter system will find this STABSOLI kit convenient and cost-effective. It’s aimed at those wanting a single, ready-to-install package—starter motor, solenoid and CDI—instead of sourcing parts separately, and for anyone needing a compact angled wrench to reach hard-to-access mounting bolts.
