The Kawasaki KX100 has a top speed of 110 km/h, produces 23 hp and weighs 76 kg.
Introduced in 1995 as a big-wheel, bored-out development of the KX80/KX85, the 99cc two-stroke KX100 was created as the natural stepping stone between minicycles and full-size 125/250 machines. It dominated the supermini class in amateur motocross for nearly three decades before being replaced by the 112cc KX112 in 2022.

O que os compradores devem saber
Supermini class stepping stone
The KX100 uses KX85 chassis geometry with larger 19in front and 16in rear wheels, making it ideal for growing teen riders. Ask the seller for engine hours rather than mileage, and prefer a bike with a documented top-end rebuild history over an unknown 'ran great last season' example.
Known weak points
Neglected KIPS power-valve assemblies carbon up and stick, killing midrange, and over-revved motors can wear the piston, rings and crank main bearings quickly. Also check for leaking fork seals, worn linkage/swingarm bearings, and hard-raced bikes with cracked subframes or bent radiators from crashes.
Two-stroke upkeep
Expect a piston and ring change roughly every 15-25 hours of racing, premix at 32:1 with quality two-stroke oil, and transmission oil plus air filter servicing after every ride day. Clean the KIPS valves at each top-end service and keep the chain, sprockets and radiator fins in good shape.
