Supplier's note

  1. Three Technical Breakthroughs:

    • CDI Ignition: Eliminates points erosion, ensuring reliable ignition cycles even in dusty environments.
    • Aluminum Fins: Reduce thermal stress by 30% compared to steel-only designs, extending engine lifespan.
    • Dual Start System: Combines electric convenience with manual redundancy for off-grid reliability.

  2. Optimal Version Selection:

    • Base Model (110cc): Ideal for casual riders or lightweight pit bikes where agility and low maintenance are priorities.
    • Advanced Model (125cc): Targets dirt bike enthusiasts needing extra torque for steep terrain or heavier riders.
    • Pro Model: Engineers optimized cooling and torque for professional racing or commercial use. For example, the Pro’s turbine-inspired fins provide 20% better heat dissipation than industry standards, enabling sustained high-speed performance. Pair this with its 9.8 Nm torque to handle rugged trails without overheating.

With the Pro’s enhanced cooling and torque, you can conquer extreme off-road conditions. The Advanced Model’s balance of power and weight suits most recreational riders, while the Base Model keeps costs low for entry-level builds.
