The Kawasaki KX™250 has more AMA motocross and supercross success than any other manufacturer in its class and returns for 2020 with a list of enhancements that are designed to keep it the best performing bike on the track. The 2020 model offers a new engine with improvements inspired by Kawasaki’s racing efforts for more top end power, as well as better handling thanks to a revised chassis and new KYB suspension components. With championship heritage that boasts 17 AMA professional titles and more than 160 race wins since 2004, the KX250 is the ideal platform for experienced riders looking to get the upper hand on their competition.
The KX250 is instilled with a high level of technology and KX™ DNA that makes it the bike that builds champions. Its power, handling and adjustability personalize the feel and provide high confidence for motocross and off-road riding, both at the amateur and professional level. The most powerful KX250 engine to date comes by the way of a revised bore and stroke, valve train designed by Kawasaki’s World Superbike engineers and bridged-box piston that is inspired by Kawasaki’s factory racing efforts. Complementing the increased power is an updated slim aluminum perimeter frame with new lower front engine mounts and a new 48 mm KYB coil-spring front fork and rear shock unit that allow for precise tuning.
• NEW engine with increased peak power
• NEW revised bore and stroke
• NEW finger-follower valve actuation
• NEW larger-diameter intake and exhaust valves
• NEW larger-bore high performance piston
• NEW low-friction crankshaft pin plain bearings
• NEW stronger cam chain and relocated cam chain tensioner
• NEW shorter intake funnel
• NEW larger throttle body
• NEW shorter exhaust system design
Acclaimed for its high output and smooth power delivery, the KX250 features a new engine with improved power, an even more potent high rpm range and a higher rev limit. Tuned to best suit race-experienced riders, the 249cc liquid-cooled, four-stroke engine focuses on more top-end rev thanks to improvements by Kawasaki’s factory racing efforts. The new engine features a revised bore and stroke that measures 78.0 x 52.2 mm. The wider bore enables the use of larger intake and exhaust valves and provides greater flow for high rpm performance.
Contributing to the race-winning engine characteristics, the digital fuel injection system of the KX250 features a coupler package that has set the industry standard. Each KX250 motorcycle comes standard with three different couplers, easily allowing riders to select pre-programmed fuel injection and ignition mapping to suit their riding style or track conditions. The four-pin DFI® couplers select maps that are designed for standard, hard or soft terrain settings. Changing the engine map is as simple as connecting the coupler cap of choice. For riders looking to fine tune their ECU settings, the KX FI Calibration Kit (Handheld) is offered as a Kawasaki Genuine Accessory, and provides access to the fully programmable ECU. The handheld device eliminates the need for a trackside laptop and gives riders the ability to create custom maps for precise adjustment of fuel and ignition settings. The user-friendly device can store up to seven preset maps and is PC-compatible.
The launch control system of the KX250 motorcycle is a major advantage and favorite for riders who are focused on getting to the first turn ahead of their competition. The push-button activation retards ignition timing in first and second gear, helping maximize traction on slippery surfaces like concrete starting pads and put the bike’s potent power to the ground. Once the rider shifts into third gear, normal ignition mapping immediately resumes and full power is restored.
▪ NEW lower front engine mounts
The slim aluminium perimeter frame uses a lightweight construction composed of forged, extruded and cast parts that contribute to light, nimble handling. Thanks to new lower front engine mounts, changing from a through bolt to stud bolts at the front of the crankcase, the overall frame rigidity has been revised with improved ability to absorb bumps. The center of gravity and key dimensions such as swingarm pivot, output sprocket and rear axle locations have all been carefully selected so that the rear tire drives the bike forward.
SUSPENSION & BRAKES
▪ NEW 48 mm KYB coil-spring fork
▪ NEW KYB shock unit complements front fork
▪ NEW Uni-Trak® rear suspension link
▪ NEW stiffer front and rear spring rates
▪ NEW revised front brake pad material
▪ NEW larger-diameter 250 mm rear disc
▪ NEW rear brake master cylinder
ERGO-FIT® Adjustable Components
Kawasaki continues its unmatched commitment towards providing riders with class-leading comfort thanks to its ERGO-FIT® adjustable handlebar mounting system and footpegs to fit a variety of riders and riding styles. The handlebars feature four-way adjustable mounts. The multi-position handlebars offer two mounting holes with 35 mm of adjustability, and the 180-degree offset clamps boast four individual settings to suit different size riders. The footpegs feature dual-position mounting points, with a lower position that reduces the standard setting by an additional 5 mm. The lower position effectively lowers the center of gravity when standing, and reduces knee angle when taller riders are seated.
BODYWORK & SEAT
• NEW factory-inspired green bodywork
Complementing the improved power and precise handling of the KX250 is minimalistic bodywork that includes slim radiator shrouds for an aggressive race-ready look. A flat fuel tank and seat design help to aid in a more seamless design, making it easy for riders to move around on top of the bike.
For 2020, the number plates and airbox of the KX250 motorcycle have been updated to the color green, resembling the same look found on the bikes used by the factory racing team. The front and rear fenders and fork guards implement a sharp design that makes the bike look more compact. Adding to the distinctive Kawasaki factory race team look is a green oil cap, generator cover plugs, green alumite suspension adjusters and black alumite rims.
