2013 Kawasaki KX Motocross Bikes Revealed – Air Forks for KX450F!
Kawasaki has unveiled its 2013 KX series motocross bikes. Both models receive updates for 2013 but perhaps the biggest change is the new pneumatic fork on the KX450F.
The KX450F has done well for Kawasaki, thanks to Ryan Villopoto’s 2011 and 2012 AMA Supercross and 2011 AMA Motocross championships.
The 2013 Kawasaki KX450F is equipped with Kayaba Pneumatic Spring Fork. The KX450F’s fork uses compressed air as an “air spring” . Kawasaki claims the pneumatic suspension allows for easier tuning, reduces friction and improve bottoming resistance while weighing 1.7 pounds less than the previous forks.
Kawasaki also updated the engine, revising ignition timing, piston crown and intake cam, promising improved bottom-end throttle control and smoother delivery through the mid-range to higher rpms.
Other updates include a new front master cylinder and a new rear brake rotor while the grips allow the rider to keep his or her hands up to 20mm closer together than previously.
The 2013 Kawasaki KX250F also received updates. It still uses Showa Separate Function Fork suspension, but it’s been refined to offer more progressive damping and uses larger 48mm inner fork tubes.
The 250 also gets a redesigned cylinder head to improve airflow from the airbox, dual injectors, and a narrower frame.
The 2013 Kawasaki KX450F will be available for $8,699 while the KX250F will be offered for $7,599.
