2013 KAWASAKI KX450F MOTOCROSS- THE SWEETEST POWERBAND POSSIBLE!! This is a fast, and very powerful motorcycle. Isn’t that what most motocross racers spend good money trying to achieve with pipes, cams, maps and head mods? I will say that this one has a FMF pipe on it. With the Kawasaki KX450F, you don’t need to spend extra cash on the ponies? well, actually, you could save your hop-up money and spend it on the ponies at Santa Anita. The 2013 KX450F comes with three plug-in maps. Kawasaki calls the maps “soft,” “hard” and “stock.” Ignore those names. Instead, call them “aggressive” (instead of soft), “mellow” (instead of hard) and “stock.”
WHAT DO THE THREE MAPS RUN LIKE?
A: Pick your poison.
Stock map (green) . This was a good map and the choice of most Novice and Vet riders. It hit with a solid rush, but it wasn’t scary. Then, in the middle, it pulled strong and fast. It didn’t rev quickly, but it was easy to get back on the pipe if you dogged it out of the corner.
Mellow map (black) . Every test rider eschewed the mellow map. It was really hooked up and manageable through the midrange and was less likely to create wheelspin. It would be the perfect choice for ice racing or if they ever have an AMA National Linoleum Championship. Its worst trait was that it didn’t jump back up on the powerband very quickly.
Aggressive map (white) . In 2012, the aggressive map hit very hard and was amazingly powerful off the bottom. For 2013 the aggressive map isn’t overbearing down low, but it revs quicker, gets on top of a gear quicker and pulls through the powerband faster. You gotta love a bike that comes with three different powerbands, that can be changed in 30 seconds.
On the dyno, there were no perceptible horsepower differences between the stock and aggressive maps. The white and green plugs are all about the feel and the speed of the engine’s turnover. On the other hand, the mellow map gave up one horsepower everywhere in the powerband.
WHAT IS THE BIGGEST UPGRADE OF 2013?
A: All the buzz revolves around the Kayaba Pneumatic Spring Forks (PSF). Replacing the steel coil springs with air means the PSF forks offer less friction, improved bottoming resistance, easier tuning and a 1.7-pound weight savings. The Kayaba air forks will set the world on fire, they are better than the Kayaba AOSS forks from the 2012 model year. This one has been fully serviced, and it is ready to ride!!!
