Specifications for a Kawasaki KX 80by Brianna Collins
One of Kawasaki's long-lived small motocross bikes, the KX 80, debuted in 1979 and was manufactured for more than 20 years. The bike was designed for kids and featured a smaller frame and a less-powerful engine than Kawasaki's adult motorcycles. Still, it provided a decent amount of speed, agility and maneuverability on the course.
Dimensions and Capacities
The 2000 KX 80 weighed only 143 pounds, making it well-suited to younger and smaller riders but an impractical ride for larger users. It measured 71.6 inches long, 28.9 inches wide and 41.5 inches high. Its wheelbase measured 49.4 inches. The KX 80 had a relatively high road clearance of 13.4 inches, allowing for more maneuverability on uneven riding surfaces. The bike could carry 1.46 gallons of fuel.
The 2000 KX 80 was equipped with an 82 cc, two-stroke, single-cylinder engine with a piston reed valve. The engine had a bore and stroke of 1.89 inches by 1.80 inches, and a 10.3-to-1 compression ratio at low speeds and 9.4-to-1 at high speeds.
A Keihin PE 26 carburetor, 32-to-1 lubrication and liquid cooling system all worked in conjunction with the engine. The 2000 KX 80 also featured a primary kick starter and a capacitive discharge ignition. The bike took NGK R6252K-105 spark plugs in a solid post terminal.
The 2000 KX 80 was equipped with a six-speed constant mesh transmission with return shift and chain drive. It also featured a wet, multi-disc clutch. Additionally, the bike took SAE 10W30 or 10W40 transmission oil, class SE, SF or SG.
Chassis and Suspension
Built on a tubular, single-down tube frame, the KX 80 had a caster angle of 27 degrees, a steering angle of 45 to either side, and a trail of 3.50 inches. In front, it had a telescopic fork suspension with a stroke of 10.83 inches. In the rear, the bike came with a swingarm, Uni-trak suspension that could travel 10.83 inches.
Brakes and Tires
The KX 80 was equipped with disc brakes in both front and back, 7.95 inches in the front and 5.91 inches in the rear. It also had Dunlop tires standard, size 70/100-17 40M in the front and 90/100-14 49M in the back.
