THE BRIDGE TO GREATNESS
Mold your aspiring racer by bridging the gap to full-size bikes with the KX™100 dirt bike. With a 99cc engine, this two-stroke super-mini gives riders the perfect blend of durability and proportionate power increase with a larger chassis before transitioning to the big bikes.
Brakes
- PREMIUM STOPPING POWER: A 220mm petal brake rotor in the front and a 184mm petal brake rotor in the rear offer progressive braking performance for confident riding. The petal design reduces unsprung weight while also helping to keep the brake pads clean and cool. The result is consistent braking performance with a firm feel.
Engine
- SUPER-MINI WITH BIG POWER: 99cc liquid-cooled two-stroke engine makes for the perfect stepping stone by bridging the performance gap from minis to full-size bikes. With proportionate power increase, this amateur champion delivers strong and instant power when the rider demands it.
Ergonomics
- BUILT TO FIT: KX™100 motorcycles grow with your young racer thanks to the ERGO-FIT® system. Featuring six-position adjustable handlebar mounts, ERGO-FIT enables riders to set their ideal ride position. Plus, larger (19F, 16R) wheels than the KX85 (17F, 14R) contribute to a taller 34.3-inch seat height and higher 13.0-inch ground clearance.
Suspension
- EXCEPTIONAL RIDE: Front and rear suspension can be tuned to the rider’s preference. The 36mm inverted cartridge fork offers 20-way adjustable compression damping and 10.8 inches of travel. In the rear, the Uni-Trak® suspension features 10.8 inches of travel and has adjustable compression, rebound and preload.
