KEY FEATURES

Stronger Brakes

Stronger Brakes

A larger-diameter ø250 mm rear disc complements the oversized ø270 mm front disc, delivering stronger stopping power.  New front brake pad material offers increased controllability.

Easy engine tuning: DFI Setting Data Selection

Easy engine tuning: DFI Setting Data Selection

Using the provided DFI couplers, riders can quickly and easily access their choice of three maps (standard, hard, soft) provided in the ECU.

Factory-inspired tuning

Factory-inspired tuning

Works-base bridged-box bottom piston is just one of many features inspired by our factory racers.

Large-Diameter Coil-Spring Fork

Large-Diameter Coil-Spring Fork

Handling suspension duties up front is a new high-performance ø48 mm inverted coil-spring fork.  The large-diameter inner tubes enable the use of large damping pistons, delivering smooth action and firm damping. Stiffer spring rates front and rear match the KX250’s increased power.

More race-winning high-rpm power

More race-winning high-rpm power

The new engine boasts an increase in peak power of approximately 2.4 kW (3.3 PS), and performance focused on the high-rpm range.  The stronger high-rpm performance, easily noticeable from 10,000 min, gives riders an advantage on the straights, and makes it easier to tie corners together for quicker lap times.

The new engine also features a short-stroke configuration, with bore and stroke measuring 78.0 x 52.2 mm.  Thanks to the wider bore, larger intake and exhaust valves can be used, enabling greater flow for increased high-rpm performance. 

Slim, Ergonomic Bodywork

Slim, Ergonomic Bodywork

The narrow frame and minimalistic bodywork offer a slim riding position that facilitates control.  A low, flat tank/seat design makes it easier to sit farther forward, and long, smooth surfaces make it easy to slide back and forth.

Adjustable Ergonomics

Adjustable Ergonomics

A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference.

Dual injectors

Dual injectors

The KX250 is the only production motocrosser with dual injectors (a feature since 2012): an injector downstream of the throttle valve (where injectors are located on standard FI systems), tasked with delivering smooth, instant response; and a second, upstream injector located close to the airbox, which makes a significant contribution to engine output at high rpm.

Slim Aluminium Perimeter Frame

Slim Aluminium Perimeter Frame

Already a very high-level frame, minor rigidity balance tweaking care of new lower front engine mounts contributes to an improved ability to soak up bumps.

KX FI Calibration Kit (Accessory)

KX FI Calibration Kit (Accessory)

KX FI Calibration Controller, a portable handheld calibration tool, enables riders to make changes to engine maps by plugging into the ECU without needing a PC or battery. Comes equipped with seven pre-set map settings.

Finger-follower valve actuation

Finger-follower valve actuation

Finger-follower valve actuation enables a higher rev limit (increased 500 min-1), and more aggressive cams for harder-hitting power.
