YAMAHA WR450F 449 (2011 - 2012) Description & History: The 2011 Yamaha WR450F sports a new fuel injection system for even better power response from the 449cc single-cylinder engine. Thanks to the acclaimed aluminium chassis inherited from the YZ250F dirt bike, the WR450F is truly a race-ready machine.
New slim bodywork with updated headlight design gives the WR450F an aggressive, tough appearance. All this, including: tool-less access air box, Excel rims, 18" rear wheel, ProTaper handlebars, wave-type brake rotors, electric start, on-the-fly clutch adjuster, and side stand. This machine is ready for tight trails, woods, or desert fun.
Even more, the 2011 WR450F sports a digital enduro computer offering speedometer, clock, tripmeter functions, etc., in basic mode—or pace management functions such as timer, distance-compensating tripmeter, average speed, etc., when switched to race mode.
