125CC 4-Stroke Engine Motor Kit, with Reverse Gear & Electric Start, Semi-Auto 4-Speed Transmission, Air-Cooled Single Cylinder, Fits for ATV, Go Kart, Quad, Dirt Bike-Black
【High-Performance Dominance】Engineered for relentless power, this 125cc ATV motor delivers 7.64HP (5.7kW) at 7500 RPM via an optimized overhead cam (OHC) configuration. The lightweight yet durable aluminum alloy block ensures seamless torque transfer for aggressive acceleration and buttery-smooth rides across rugged terrain.
【Advanced Thermal Management】A precision-engineered forced-air cooling system achieves 30% faster heat dissipation than standard designs. Integrated heat-resistant alloys and directional airflow vanes maintain optimal operating temperatures, eliminating power fade during prolonged high-RPM adventures.
【4-Speed Dynamic Control】Master any terrain with a CNC-machined 4-speed manual transmission featuring helical-cut gears. Engineered for ±0.2mm shift precision, its oil-bathed clutch system enables instant gear transitions—perfect for conquering rocky trails, sand dunes, or muddy tracks without drivetrain lag.
【Sealed Defense Technology】IP54-rated enclosure with triple-layered gaskets blocks particulate ingress (dust/water/oil) to 15 microns. Maintenance intervals extended by 50% compared to open-frame engines—ideal for extreme environments requiring minimal upkeep.
【Simple Details】Engineered for effortless operation, this ATV motor supports CDI ignition systems (sold separately) for high-energy efficiency and quick, safe starts. Its pre-assembled core minimizes installation effort—simply complete remaining components for a streamlined, rewarding setup. Combines user-friendly design with robust performance for reliable power and hassle-free maintenance.
