2027 Kawasaki KX 85

Meet the 2027 Kawasaki KX™85 in Lime Green—a youth MX machine that looks like it’s already halfway down the start straight just sitting still. Built to help rising riders sharpen skills and chase faster laps, this lightweight, razor-responsive package brings real motocross attitude in a right-sized ride.

At the heart of it is a liquid-cooled, single-cylinder 2-stroke with a reed-valve setup and 84cc of hit-the-gas excitement. Fuel is gas/oil injected and fed through a Keihin 28mm carburetor, giving it that classic 2-stroke snap with a modern, ready-to-rip feel. When it’s time to roll, a kick starter keeps things simple and race-focused, and a 6-speed manual transmission (with overdrive) lets a rider keep the engine in the sweet spot as the track opens up.

The steel frame and plastic bodywork are built for the real world of youth motocross—roost, ruts, and the occasional “creative line choice.” Up front, an inverted 36mm fork delivers 10.8 inches of travel, with adjustable preload and rebound damping so you can tune the feel as confidence grows. Out back, the UNI-TRAK® rear suspension pairs an aluminum swingarm with 10.8 inches of travel, plus adjustable preload and rebound to help keep the rear end planted when the track gets choppy.

Rolling on aluminum wheels with tubed Dunlop® Geomax MX34 tires (70/100R17 front, 90/100R14 rear), it’s set up to bite into berms and hold a line through loose corners. Disc brakes front and rear—240mm up front with a 2-piston caliper and 220mm in the rear—give controllable stopping power for late braking practice and cleaner corner entries.

With a one-piece vinyl seat at 32.7 inches, a slim, purposeful stance, and a wet weight of 164.4 lbs, this Lime Green KX™85 feels like a serious race bike—because it is. Add in practical touches like fork guards and an exhaust guard, and you’ve got a youth MX motorcycle that’s ready to train, sprint, and send it—lap after lap.
