When released in 2012, the all-new WR450F heralded the biggest change since the introduction of that first WR400F. Yamaha designers, testers and engineers have revisited the drawing board and re-invented the new WR450F from the ground up.
The challenge was how to improve on an already peerless motorcycle. But the team stepped up to the mark and delivered a motorcycle that the whole nation has been hanging out for… a bike that retains the hallmark features of reliability with the versatility to win at the highest level while still providing an easy-to-ride trail weapon.
The handling goal has been achieved with the development of a new aluminium bilateral beam frame that is very similar to the much hailed, latest-generation YZ250F frame that offers scalpel sharp steering and rail-like turns.
To complement the new frame, new YZ inspired twin chamber suspension is fitted front and rear to soak up the harsh terrain that fast trail and competition enduro riders encounter. Once again, the suspension is specially enduro-tuned by combining the ability to absorb big hits with a softer initial travel to tackle tight turns.
And in order to offer stable engine performance irrespective of fluctuations in air temperature or altitude, a fuel injection system has been adopted. This can easily be adjusted with a hand held, portable Power Tuner device, the same unit that has proven so popular with YZ450F owners.
