There are times when we wish we could go back and start over on a bike like the YZ85, knowing what we know now. But it's now the bike for the future generations to learn on. Have fun, gang.

2009 Yamaha YZ85 

ENGINE:

  • 84.7cc 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.
  • Lightweight exhaust system design helps create a broader powerband with stronger low-end punch.
  • Airbox design ensures greater air cleaning performance and easier maintenance.

CHASSIS/SUSPENSION:

  • Rear subframe is removable to allow easy maintenance.
  • Lightweight 36mm KYB® inverted cartridge fork features 10.8 inches of travel with compression and rebound damping adjustability, and low-friction outer tubes and internals.
  • Rear suspension features fully adjustable Kayaba link-type shock with 11.1 inches of travel and race-tested compression damping valving.
  • 220mm front disc and 190mm rear disc brakes with stainless steel rotors deliver strong, precise stopping power.
  • Lightweight 17-inch front and 14-inch rear rims are durable and reduce unsprung weight for optimal suspension performance.
  • Dunlop® knobbies provide great traction on a variety of tracks and terrain.

ADDITIONAL FEATURES:

  • Wide handlebar and flat fuel tank, radiator shrouds, side panels and rear fender provide rider with leverage and freedom of movement and weight transfer.
  • Wide footpegs provide superb comfort, grip and ground clearance.
  • Separate clutch cover with transmission oil filler opening makes for easy maintenance.
  • Fuel tank cap is wider-diameter for easier usage, and large tank opening ensures fast, hassle-free refueling.
  • Repackable exhaust silencer.
