Check out the 2013 Kawasaki KX450F as MotoUSA put it through the paces at California’s Zaca Station Motocross track. Read the full details in our 2013 Kawasaki KX450F First Ride article.
- The new 48mm KYB Pneumatic Spring Fork (PSF) uses pressurized air to eliminate the traditional metal-coil fork springs.
- A 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.
- A revised piston crown improves low to mid-range engine response.
- New ECU settings offer smoother power delivery when transferring from low to high RPM making it easy to clear jumps from inside lines.
- Launch Control improves low-gear acceleration by helping to reduce wheel spin off of a start.
- The KX450F comes with three different mapping couplers, standard, hard terrain, and soft terrain.
- We found that the new Pneumatic Spring Fork was just about impossible to bottom out even on hard landings.
- Our pro test rider Scott Simon had no problems throwing the KX around.
- Test rider, Simon, was not afraid to get a little bit nasty over the bigger jumps at Zaca Station.
- With a choice of four different handlebar positions, two footpeg positions, and virtually unlimited ignition mapping capabilities, the KX450F is able to adapt to changing track and surface conditions.
