The 2006 Honda CRF450R brings in quite a spectacular set of improvements to the Unicam engine, now fueled by a lager carburetor and sporting a smaller exhaust valve, lighter decompression system, a new ignition map, stronger clutch basket and lighter covers, and anew throttle pump and linkage.
15% improved braking power for the front caliper, better tires, a revised exhaust and revalved front suspensions are also on the menu for this year's iteration of the highly successful and equally revered machine.
