Vehicle Information
Yamaha Grizzly 350 ATV (2007-2021)
The Yamaha Grizzly 350, produced from 2007 to 2021, established itself as a reliable and robust utility ATV. Powered by a consistent 348cc air/oil-cooled, single-cylinder, SOHC, 4-stroke engine with a Mikuni 33mm BSR carburetor, this model was known for its durability rather than peak horsepower. It maintained a largely unchanged engine and transmission (Yamaha's Ultramatic V-belt automatic) throughout its production run, focusing on dependable performance for work and recreation. While the core platform remained consistent, the Grizzly 350 offered key variations in its drivetrain and suspension. Models included the 2WD Automatic, the 4x4 Automatic with Yamaha's On-Command system, and the notable IRS Auto 4x4. The Independent Rear Suspension (IRS) trim provided enhanced comfort and improved handling over rough terrain compared to the standard swingarm rear suspension, representing the most significant differentiation within the series rather than a full generational change. This consistency underscores its reputation as a "no-frills workhorse." Q: Is this product compatible with my Yamaha Grizzly 350?
A: To ensure perfect compatibility, please use the year and edition selector at the top of this page. This will filter products specifically designed for your ATV's configuration. Q: Did the Grizzly 350 receive any major engine or chassis updates between 2007 and 2021?
A: The Yamaha Grizzly 350 maintained a remarkably consistent design and engine specification throughout these years. While different trims offered variations like Independent Rear Suspension, there were no major generational overhauls or significant engine changes during this period.
