2012 YAMAHA Grizzly 350 4x4

The Yamaha Grizzly 350 pulls no punches as far as its capabilities are concerned. The no-nonsense all-utility vehicle takes pride in being one of the most reliable ATVs on the market, so it really isn’t that hard to believe that this machine packs a wallop.

The lightweight and advanced design of the Grizzly 350 owes itself to Yamaha ’s superb engineering. Among the unique features of the ATV include a specially designed seat that offers tremendous rider comfort; steel cargo racks that can carry a combined cargo capacity of 264 pounds; a standard, center-mounted trailer hitch that can carry more than 1,100 pounds of payload; front and rear fenders with inner guards; dual, bright, multireflector 30-watt Krypton bulb headlights with high and low beams; and a water-resistant, large-capacity underseat storage box that provides added convenience; among other things.

Inside the Grizzly’s lightweight, CAD-designed chassis, you’ll find a 348cc air/oil-cooled, SOHC four-stroke single engine that produces stump-pulling bottom-end power. The engine then transmits its power through the legendary Ultramatic V-belt transmission while a full automatic centrifugal clutch system with a fully sealed drive case ensures constant, no-slip belt tension with the added confidence of all-wheel engine braking. Speaking of the brakes, the Grizzly 350 carries large-diameter ventilated hydraulic dual front discs and sealed rear drum brake which is more than a match for the task.

The Grizzly 350 won’t win any beauty contests. Instead, it offers all-world reliability and power that few ATVs on the market can match.
