Supplier's note

  1. Three Technical Breakthroughs:

    • CDI Ignition: Eliminates points wear, ensuring consistent starts even in dusty environments.
    • Centrifugal Clutch: Reduces maintenance by eliminating belt slippage common in traditional designs.
    • Electric Starter: Enables instant ignition in cold starts, a critical advantage for winter riding.
  2. Optimal Version Selection:

    • Base Model: Ideal for casual riders or budget-conscious buyers seeking reliable 250cc power.
    • Advanced Model: Perfect for trail riders needing 8% better fuel efficiency and lighter weight.
    • Pro Model: Designed for racers or extreme terrain users, with 14% improved fuel efficiency and hybrid cooling that extends engine lifespan in high-stress scenarios.

*Pro Model’s 28.6 HP output exceeds industry benchmarks by 20%. **Hybrid cooling combines air and oil-jet systems for peak performance in temperatures up to 50°C.

With its centrifugal clutch, you can shift seamlessly between gears without manual clutch control. With the Pro Model’s hybrid cooling, you can sustain high RPMs longer during off-road rallies.
