2009 Yamaha YZ450F
In addition to the Yamaha’s outstanding suspension compliance, once you set rider sag (between 102-106mm), you’re not going to need to make a whole lot of adjustments, as the baseline suspension settings out of the box suited our group well. Throughout the day our Yamaha tech had to have been bored out of his mind because none of our testers felt the need to make nearly any adjustments.
Although the ’09 YZ450F benefits from a new swingarm, rear suspension linkage, and rear hub, we couldn’t notice a difference. What we did perceive however, are the same mild-mannered handling traits we enjoyed on last year’s bike. Although the Yamaha isn’t the sharpest turning, it does turn well and never catches the rider off guard. Add in the unflappable chassis and high level of stability and it seems nothing can faze the Yamaha.
