    • Mechanical power valve system delivers effective exhaust timing throughout the entire rev range
    • Provides excellent power and torque characteristics
    • Delivers responsive acceleration just as the rider intends
    • Slit-shaped valve on the side of the exhaust port operates in response to engine rpm
    • In low-to-mid-rpm range when exhaust timing is slower, valve moves to cover the top part of the exhaust port
    • In high rpm range when quick exhaust timing is needed, valve recedes and exhaust port is fully uncovered
    • Valve control governor from YZ125 and YZ250 employed
  • Newly-designed 2-petal reed valve.
  • Optimized crankshaft balance and lightweight connecting rod.
    • Resin weight in crank web creates high primary compression ratio and optimal inertial mass
    • Delivers instant power delivery and reduced vibration
  • New intake manifold and exhaust pipe.
    • Optimal intake and exhaust layout complies with racing regulations
    • Short exhaust produces rippling sound unique to a 2-stroke
    • Expansion chamber designed for plenty of volume
    • New design pays special attention to pulses that occur during combustion flow to contribute to explosive but easy-to-use power
