New Kawasaki: Introducing the 2013 KX250F and KX450F

News - New Kawasaki: presentation of the KX250F and KX450F 2013 - KX450F 2013: it does not lack air!

In off-road conditions as in speed, which does not move forward, backwards: Kawasaki has understood this well by bringing subtle changes to its 2013 motocross range. Even more competitive, the KX250F and KX450F have only one objective: the win ! Presentation.

2013 KX450F: there’s no shortage of air !

Efficient and sophisticated (with notably "Launch Control" starting assistance and three maps on the handlebars), the 2012 KX450F is already a formidable tool: the double of the official bike in the world championship in Sevlievo (Bulgaria) and its coronation in SX and American MX are there to confirm it.

Kawasaki has however decided to set the bar higher to seek the world crown in 2013. For example, the engine of the 450 sees its low and mid revs improved through the use of a new piston cap and reprogramming of its housing. electronic.

The novelty Kawasaki retains its flexible driving position: the handlebars offer four different positions and the toe clips can be moved to two different notches. A delicate attention, so important it is to be well installed off-road – perhaps even more than on a road bike !

Like the 250 cc, the KX450F receives a new front master cylinder and more "beefy" brake pads that bite new discs. Its look is also refreshed: the mudguards are redesigned and the aluminum of its rims and fork guards receives an oxidation treatment called Alumite, which provides a protective film very resistant to scratches and corrosion..

But the main change adopted by the Kawasaki KX450F 2013 concerns its front axle: the "traditional" spring fork gives way to a pneumatic type element, where the compressed air performs the damping functions..

According to Akashi engineers, this fork called "PSF" would be less prone to tailgating, would offer a "better track holding"and a wider range of settings.

"Pilots are not limited to only basic or optional settings of spring systems", assure the Greens by recalling that an inflator and an adapter are enough to intervene on the settings of an" air "suspension.

Used for the first time in series on a motocross, the air fork also has the advantage of being lighter than a spring model. On the other hand, one of its drawbacks lies in its sensitivity to temperature variations: subjected to strong constraints, the air heats up, expands and no longer offers the same damping capacities. Hence a sometimes delicate focus…

Kawasaki, however, had to find solutions to avoid this phenomenon – which explains the confidentiality of this technology – to ensure exemplary course holding for its "beast" of cross country circuits !

Prices and availability of the new Kawasaki KX250F and KX450F will be communicated later, knowing that the Greens’ cross-country novelties generally tumble during September (read in particular). To be continued on Site: stay connected !
