2013 Kawasaki KX450F and KX250F

These two machines were the starting point for a whole bunch of major titles last year. What have they changed for 2013?

2013 Kawasaki KX™450F

Highlights for this year's KX450 start with a new 48mm Kayaba Pneumatic Spring Fork (PSF) that replaces the main fork springs with compressed air. You get 1.7 pounds of weight savings, and Kawasaki also claims provide easier and more effective tuning, as well as improve bottoming resistance. The 32mm internal damping cartridge are much larger than last year's, which had 24mm pistons. DLC coating on the fork tubes minimize sticktion, as does the internal Kashima coating. A removable spring pressure adjustment valve is also included.

The engine receives minor updates, with a revised piston crown for a boost in ultra-low to mid power, as well as cam changes for better low rpm response.

Other details include a new front master cylinder with a knocker-style lever-to-piston connection for improved feel, and returning items include the Launch Control introduced last year, as well as the adjustable handlebar and footpeg mounts.

2013 Kawasaki KX™250F  

The new in the new 2013 KX250F starts with a shorter stainless steel headpipe with resonator chamber for an added low-rpm kick, and a new high volume muffler that's shorter, but with a larger cross-section, designed to keep noise levels at 94 db while maintaining power.


Kawasaki's also using an upgraded 48mm Separate Function Fork (SFF) with new 1mm larger inner fork tubes that allow the internal damping components to be larger, for firmer damping response. There's also a new swingarm that features a longer cast front section, as well as tapered hydroformed spars and forged chain adjusters. The size of the sideplates has been reduced, you can look for a new pushrod style configuration at the front master cylinder, and new brake pad material. New radiator shrouds and the aforementioned smaller side panels make things slimmer than ever.



Revised goodies? The intake tract is straighter than ever, for a more direct flow of airflow; and a revised piston profile for better durability. The lower triple clamp has also been opened at the back for increased rigidity and improved fork action
