YAMAHA Grizzly 450 IRS (2008-2009) Specs, Performance & Photos
Segment: ATV/Quad
Production years: 2008, 2009
The 2008 Yamaha Grizzly 450 IRS is a smaller version of the 550, built for those riders on a slightly tighter budget, looking for a small-to-middle displacement off-road machine, and yet ruling out compromise from theirs ATV shopping list. This quad sports the same independent, adjustable suspensions of its bigger siblings and is by no means a slacker: its scaled-down engine still comes with an Ultramatic transmission and parking brake, intuitive operation and on-command AWD with a lockable differential, ready to tackle the rough trails.
Good ground clearance and hydraulic brakes make the 2008 Yamaha Grizzly 450 IRS suitable for tougher jobs in the open, allowing riders to lorry and tow gear and objects on the trails and on rough ground. Great for work and for off-road explorations, this ATV can really do things and go places, without leaving a burning hole in your pocket.
