Ensure reliable ignition every time with the OKO High Torque GY6 Starter Motor. While standard starters often struggle to turn over modified engines, this reinforced unit is specifically engineered with high-strength internal windings to provide the extra cranking power needed for 125cc and 150cc GY6 engines equipped with Big Bore Kits or Stroker cranks.
By delivering higher rotational torque, this motor reduces strain on your battery and electrical system, preventing the "solenoid click" common in high-compression builds. It features a heavy-duty 9-spline shaft and weather-sealed housing for long-term durability in all riding conditions.
Universal fit for most 125cc–150cc 4-Stroke GY6 engines, including:
Tech Tip: If you have recently installed a Big Bore Kit and your starter sounds "sluggish," your stock motor is likely underpowered for the new compression ratio. This OKO High Torque unit is the direct solution. We also recommend inspecting your Starter Solenoid and battery cables for corrosion to ensure maximum current flow.
Note: This is a 2-bolt mounting style motor. Please verify your original starter uses the same 78mm bolt spacing before ordering.
