2014 Kawasaki KX 100 Preview
For those have outgrown the KX85 but are not quite ready for the KX250F, Kawasaki built an in-between motocross machine that bridges the gap – the KX100 two-stroke.
The KX100 arrived on the scene in 1996, replacing the KX80 “Big Wheel.” Though a potent machine, Kawasaki kept the MX bike relatively the same.
But this changes for 2014. Kawasaki has revamped the KX100’s two-stroke engine, which produces 17-percent more horsepower over last year’s model. The engine features a host of improvements (listed below), including the use of new technology, such as Kawasaki Integrated Power-valve System (KIPS). The power band is wider due to the use of KIPS, “which amplifies the KX100’s low-end torque and creates a more seamless transition to its furious top-end rush.”
Kawasaki also upgraded the KX100’s suspension, the motocrosser featuring revised valving in the KYB 36mm inverted fork up front, and a new Uni-Trak linkage-equipped KYB reservoir shock out back.
Kawasaki says “just like its big brothers, the KX100’s fork now features shim-type valving and firmer damping for faster riders while also offering superior bottoming resistance, but a wide range of adjustability allows it to be tailored for precise damping to fit a variety of riding styles as well as track conditions. Out back, the new shock’s black-anodized aluminum body is 150 grams lighter, while a new clicker-type adjuster makes fine-tuning the rear suspension damping quick and easy.”
To stop the lightweight two-stroke motocross machine, the KX100 uses 220mm front and 184mm rear rotors. The KX100 is also wrapped in new Dunlop Geomax MX51 intermediate tires, which provide optimal grip across a variety of off-road terrains.
Ergonomics were also improved, from the 34.3-inch tall seat to a six-position adjustable wider and taller handlebar. And also, bolder graphics and unique styling were added to the 2014 Kawasaki KX100, such as blue alumite coatings on the adjusters and black alumite coating on the rims, just like three-time AMA Supercross Champion Ryan Villopoto’s factory KX450F.
Kawasaki has yet to release an MSRP on the 2014 KX100, but is expected to soon. And as always, those who compete on the KX100 at designated events are eligible to receive support from Team Green, Kawasaki’s amateur racing support program.
Following are the features and specs of the 2014 Kawasaki KX100.
