Kawasaki now offers the KX250F motocross model as a 2010 model year. Not only that, but the quarter-liter racer is entirely new as a result of engineers aiming towards a higher revving and implicit more powerful, but also more reliable engine. Once you’ve done that, every single piece of the machine qualifies for a proper revision and that’s how dirt bikes end up being tweaked each and every year.

Introduction


In order to know what needs to be improved on a bike, there’s the need for proper feedback and the fact that Kawasaki competes in the AMA Supercross Championship did help engineers come up with the right answers.

The bike needs to remain one of the sharpest steering dirt bikes in its class and the fine tuning is supposed to make that possible. Also, speed is of the essence as the engine now gets a new piston with a bridged-box bottom, which is a first on production bikes. The piece of crucial importance for any engine stands both for performance and reliability. These aspects are also covered by the electrofusion treatment on the cylinder bore, revised oil pump rotors and a wider big-end bearing that this new model year features. The radiators are increased in size in order to cope with the new temperatures involved and also weigh less, just like the entire new engine does.

Kawasaki claims their new KX250F will even vibrate less, while the transmission and clutch have been optimized for the new engine.

While this Kawi’s aluminum perimeter frame doesn’t come as a surprise, the news in the chassis chapter is the even lower center of gravity and front-to-rear weight distribution. This last aspect is achieved due to the racing suspensions and mostly the swingarm. The bike is claimed to be more stable and precise; in other words, faster around the track.

Ergonomics have also been modified for a more natural riding position and the styling is totally new on both bikes. The Kawasaki KX250F Monster Energy is simply a lighter, faster and more aggressive piece of machinery, but still a 2009 model year for now.
