After adding a 5th gear to the previous year model, Kawasaki took the KX450F to the drawing board once more, for the new season. The 2007 Kawasaki KX450F sports a much smoother-shifting 5-speed gearbox while retaining all its racing character and legendary reliability, not offering a more linear power distribution for predictable behavior.

After 2008 brought the first Kawasaki KX450F with electronic fuel injection, it was time to take things even further, so the 2008 model comes with a tweakable ECU, allowing expert riders to finely-tune their engines in order to get the best performance. The bike's computer is already self-adjusting according to the riding style, but the optional KX FI Calibration Kit is the ultimate tool.
