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.
- Increase in Peak Power making for stronger high-rpm range
- Wider bore, larger intake and exhuast valves can be used, enabling greater flow for increased performance
- Finger-Follower Valve Actuation
- Slim Alumimium Perimeter Frame
- Stronger, large diameter 250mm rear disc brakes
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.
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.
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.
