The Honda CRF450R is one of the elite motocross machines, and one of the very popular choices among dirt riders. A championship winner on multiple occasions, this machine receives a host of updates in 2005. The engine cases have been revised and the engine is now tilted forward for a lower position enhancing maneuverability. The radiators also went lower, and the water pump components now provide a longer life.
The front hub is lighter and stronger, with the forks also lightened, plus revalved suspensions, carburetor revisions and relocated exhaust for better mass centralization.
