Will this starter motor fit my ATV or mini bike?

Compatibility centers on engine size and the 3-bolt mounting pattern. This starter kit supports most 50cc–125cc Chinese 4-stroke machines, including many Taotao, Coolster, SSR, Roketa, Baja, Icebear, Kazuma and Vitacci models listed below.

• Compatible engine sizes: 50cc, 70cc, 90cc, 110cc, 125cc
• Common compatible models: Tao Tao ATA-110/125 families, Coolster 3050/3125 series, Kazuma Falcon 90, Vitacci Hawk & Rider models
• Fitment requirement: confirm your vehicle uses a 3-bolt starter mounting pattern (not 2-bolt)

What parts are included and what tools are needed for installation?

The kit ships with the starter motor plus the usual electrical and fastening components so you can replace the assembly without sourcing extra parts. Basic hand tools are sufficient for most installs; the package even includes three screws and a small wrench.

• Included items: starter motor, starter solenoid relay, CDI box, spark plug, 3 screws, wrench
• Tools typically required: socket set or ratchet, screwdrivers, basic pliers
• Installation note: direct replacement—no drilling required if your mount is a 3-bolt pattern

How reliable and durable is the EOPOAYI starter assembly?

The starter motor is built from durable components and tested to deliver strong cranking force for quick starts. While longevity varies with use and maintenance, the kit is intended as a robust replacement with OEM-style connections that reduce electrical failure points.

• Design focus: strong starter torque for fast engine turnovers
• Construction: metal housing and sealed electrical terminals to resist wear
• Maintenance tip: keep battery and wiring in good condition to maximize life

How do I confirm which bolt pattern my vehicle uses?

Visual inspection of the starter mounting flange reveals whether your starter is a 3-bolt or 2-bolt design. If you see three evenly spaced mounting holes on the starter flange, this EOPOAYI 3-bolt kit should match; if uncertain, compare photos or ask a mechanic before ordering.

• Simple check: remove or view existing starter and count mounting holes
• Measure: verify hole spacing matches your mounting flange if possible
• Contact support: message the seller with model/year for help confirming fit
