The winning edge.
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.
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.
While maintaining the slim ergonomics and highly acclaimed light handling of its predecessor, the new KX250 offers an improved ability to soak up bumps care of a new KYB coil-spring fork and revised lower engine mounts that fine-tune the frame’s rigidity balance. The resultant increase in stability and more planted feel on rough terrain on straights and through corners deliver a superb balance of nimble handling and stability that make the new model an even more potent track weapon.
