ENGINE

  • Potent YPVS™ Two-Stroke Engine
    The 85cc liquid-cooled, two-stroke engine features the Yamaha Power Valve System (YPVS™) for broad power across the rev range without losing peak power at high rpms, reducing the need for frequent shifting.

    Carefully matched to suit the YPVS™-equipped engine, the exhaust expansion chamber optimizes gas flow for enhanced power delivery, especially in the low- and mid-range.
  • Durable Transmission
    The transmission features oversized gears to provide enhanced engagement and smoother shifts.
