Miscellaneous

Engine:

• 85cc liquid-cooled, crankcase reed-valve-inducted, two-stroke engine inhales through a 28mm Keihin® flat-slide carburetor; seamless throttle response across the powerband is the result.
• Digital CDI ignition system puts out a more precise spark and monitors engine speed to ensure optimal timing for quicker, stronger response during hard acceleration.
• Smooth-shifting, six-speed close-ratio transmission with heavy-duty, multiplate clutch delivers maximum hookup for outstanding acceleration and corner-exiting power.
• Involute spline set-up in clutch means smoother shifting under power with great durability at competition-level usage.
• Two-piece clutch cover provides easy access during maintenance.
• Lightweight radiator has large cores and louvers, and the water
pump features a cast aluminum (vs. resin) impeller for maximum cooling efficiency.
