KX 250

LIGHTER, FASTER 250cc MOTOCROSSER
The KX design philosophy – to put midlevel to expert riders on the top step of the podium – has not changed since the brand was launched over 40 years ago.The KX250F has a history of winning: in the extremely competitive 4-stroke 250cc class it is the racer with the most AMA Supercross and Motocross titles. Adding to its highly acclaimed engine and chassis performance, numerous industry firsts and advanced technology, the 2017 model offers a more powerful engine, a significantly lighter chassis, and slimmer ergonomics, making the new model the fastest KX250F yet. In fact, the new model gets around the track 1.6 seconds quicker* than its predecessor.
POWERFUL, HIGH-REVVING DUAL-INJECTION ENGINE WITH FACTORY-STYLE TUNING
Tuned to best suit race-experienced riders, the 249 cm3 liquid-cooled, 4-stroke Single’s wide powerband focuses on high-rpm performance and extends way into the over-rev. Highly acclaimed for its high output and smooth power delivery, the 2017 model KX250 backs up its dualinjected power and race-inspired tuning and parts (like the high-performance bridged-box bottom piston) with downdraft-style intake routing and reduced mechanical loss (care of an offset cylinder and plateau honing, among other tweaks), resulting in a stronger lower end as well as a 1 kW increase in maximum engine output.
Lighter & lighter handling
A revision of engine and chassis components results in 1.7 kg in weight savings, bringing the already light KX250F down to a trim 104.3 kg.The lighter weight and repositioned engine contribute to lighter overall handling.
RACE-READY SUSPENSION
The KX250F was the first mass-production motocrosser to feature Showa’s Separate Function front Fork (SFF), which separates damping and shock absorption duties: * Left fork tube: damping assembly * Right fork tube: spring The configuration offers both smooth action and firm damping performance – a combination difficult to achieve with a conventional fork.
