The KX™450F has been updated for 2013 to help continue its back-to-back
string of recent championships. The string began with Monster Energy®
Kawasaki’s Ryan Villopoto winning both the 2011 Supercross and 2011
Motocross titles, followed by leading the U.S. team to an overall
victory at the Motocross of Nations, then Villopoto’s absolute
domination of the Monster Energy Cup —which also earned him the Monster
Million. Last but not least, Villopoto recently defended his Supercross
title by winning the 2012 championship on his KX450F!
•
New Kayaba Pneumatic Spring Fork (PSF) replaces the main fork springs
with compressed air to reduce weight, provide easier and more effective
tuning and improve bottoming resistance
• Revised
engine tuning offers more power and smoother delivery from basement revs
through mid and into the upper rpm range; this provides more thrust
while exiting corners and all the way down the straights, while also
enhancing rider confidence
• Revised piston crown improves ultra-low to mid-range engine response
• Revised intake cam features slightly less lift, to promote better low-rpm throttle response
• New front
master cylinder features a knocker-style lever-to-piston interface for
improved feel and more consistent performance than the old piston-type
unit
• New
longer, lower density grips make life easier on the rider’s hands. They
also extend further towards the center of the handlebars, allowing
riders to move their hands up to 20mm closer together
• New
lightweight 240mm petal-type rear rotor features the same aggressive
petal style as the front rotor and is gripped by a single piston
hydraulic rear caliper
• Launch Control improves low-gear acceleration by helping to reduce wheelspin during the run to the first corner
• Pre-programmed ignition maps are interchangeable trackside, no PC required
• Adjustable 4-position handlebar and 2-position footpegs allow riders to fit the KX to match their personal preference
• Black Anodized Aluminum rims for a factory look
