Upgrading Kawasaki's KX450F
With all new & more adjustable ergonomics, a slimmer chassis, better shocks & some tricky electronics (including a launch control system), the 2012 KX450F is a big step up, and the best in years.
But if you have a 2011, don't despair. You can get it to turn in harder & faster for tight corners, handle rougher tracks & improve the ergonomics dramatically too. With the right mods, the older bike can still be the better bike.
