Kawasaki 2020 KX250 for Sale at Maroochydore Kawasaki in Maroochydore, QLD | Specifications and Review Information
Most Powerful 4-Stroke KX250 to Date
The KX design philosophy - to put mid-level to expert riders on the top step of the podium - has not changed since the brand was launched over 40 years ago. Designed to continue its history of winning - in the extremely competitive 4-stroke 250cc class Kawasaki race machines have the most AMA Supercross and Motocross titles - the 2020 model KX250 features a new engine with increased power, an even more potent high-rpm range, and a higher rev limit. Complemented by a lightweight, well-balanced chassis with a new fork and stronger brakes, this performance advantage translates to quicker lap times, making it the quickest KX250 to date.
FACTORY-STYLE ENGINE COMPONENTS AND TUNING
Highly acclaimed for its high output and smooth power delivery, the 2020 KX250's new engine features even stronger high-rpm focused performance and increased power. New bore and stroke offer the space for larger intake and exhaust valves, while finger-follower valve actuation like the KX450 enables a higher rev limit and more aggressive cams. Dual injectors, downdraft-style intake, and race-inspired tuning and parts add to performance.
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-1, gives riders an advantage on the straights, and, when combined with a higher rev limit, makes it easier to tie corners together for quicker lap times.
REVISED BORE AND STROKE
The new engine 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. Likewise, the shorter stroke lends itself to the high-rpm focused engine character.
FINGER-FOLLOWER VALVE ACTUATION
Like the KX450, the KX250 features a valve train designed by Kawasaki's World Superbike engineers. Finger-follower valve actuation enables a higher rev limit (increased 500 min-1), and more aggressive cams for harder-hitting power.
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.
Works-base bridged-box bottom piston is just one of many features inspired by our factory racers.
EASY ENGINE TUNING: DFI SETTING DATA SELECTION (3 MAP CHOICES)
Adjusting engine settings to suit conditions has never been easier than with the KX's FI couplers. Plug-and-play style system is quick, easy and stress-free. Instead of a single engine map, the ECU features three (four, counting the Launch Control Mode map). Initial settings for the three maps are: Standard (green), Hard (conditions)(black) and Soft (conditions)(white). Using provided FI couplers, riders are able to easily switch between the three maps to suit riding conditions. Plugging in each of the 4-pin couplers activates the corresponding engine map. (Plug is conveniently located on the right side of the head pipe for easy access without having to remove any parts.)
Each of the three maps can be reprogrammed using the optional KX FI Calibration Kit.
PRECISION ENGINE TUNING: KX FI CALIBRATION KIT (ACCESSORY)
The updated KX FI Calibration Kit features the handheld KX FI Calibration Controller, which enables expert riders to adjust engine characteristics (by rewriting actual data maps) to suit their preference. This simple tool can be used without a PC, simply by plugging into the engine's ECU.
The KX FI Calibration Controller is handheld tool with a built in colour LCD screen. It comes with transfer and diagnostic cables, SD memory card, user manual and a carrying case.

THE HOLESHOT ADVANTAGE: LAUNCH CONTROL MODE
The KX250 features a launch control system similar to that on our factory racers. With the simple press of a button, riders can activate a separate engine map designed to ensure efficient race starts in slippery conditions. The Launch Control Mode map retards ignition timing, allowing tyres to gain grip in low traction situations. Launch Control Mode has the greatest effect within the first few seconds of releasing the clutch off the start. This is the most crucial time for the rider to get ahead of their rivals and line up the first corner.
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.
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. The fork's improved ability soak up bumps at the initial part of the stroke is complemented by increased firmness for handling large impacts. Increased front-end feel and an overall increase in stability facilitate machine control on rough surfaces, allowing riders to push harder with confidence.
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.
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.
A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference.
