2012 Yamaha WR450F
The bike that's universally credited with kickstarting the modern era of four-stroke enduro bikes has now had a major revampYamaha’s perennially popular WR450F enduro bike – which started life as a WR400F in 1999 --- has been overhauled for the 2012 model year, headlined by a new aluminium bilateral beam frame.
The frame is very similar to the one found on the 2012 YZ250F, but with enduro-specific dimensions, different engine mounts and a new mounting position for the subframe – which itself is comprised of a new aluminium alloy. To complement the new frame, new YZ-inspired twin chamber suspension is fitted front and rear.
The WR-F is now fuel injected, which can be adjusted with a hand-held, portable Power Tuner device, the same unit that has proven so popular with YZ450F owners.
This pocket-sized Power Tuner is easy to carry around and operation is simple when connected to the new WR450F via an easily located coupler. Setting changes can be made without the need to cart around a laptop. The Power Tuner offers riders a huge benefit by allowing customised fuel injection settings to fit their personal preferences.
The 450cc engine retains its liquid-cooled, five-valve, single-cylinder layout. A special cam profile has been developed to suit enduro RPM use, while the five-speed gearbox has ratios suitable to cover a wide range of riding environments.
The exhaust pipe has a built-in resonator which is designed to improve power output in the low to mid-range. In addition, the radiator is all new with a wider core, increased reliability and more shock resistance than previously.
There are a host of other minor changes, including an enduro seat with new cover, a new plastic resin 7.2-litre fuel tank, a fuel level warning light, and a new set of clothes with black Excel rims, a new headlight cover, side covers and graphics.
The target customer is the fast trail rider and expert enduro rider.
The new WR-F will go on sale in early 2012 fully equipped to ADR requirement. A competition enduro kit will also be offered for those wishing to indulge in closed course riding or racing.
Full specification and model information release will be made at the Sydney Motorcycle Expo in Darling Harbour starting on November 25, 2011.
In the meantime, Yamaha is offering a great deal on the 2011 WR450F, with up to $1000 Yamahdollars; a free pit tent and jet washer; finance rates from 5.99 percent.
