2012 Yamaha Grizzly 450 4x4


The Yamaha Grizzly 450 has made a name for itself as an ATV that features the ideal mix of off-road capability, reliability, and comfort in a rugged, mid-size package. It’s capable of conquering tough terrain and even tougher chores, thanks to a set-up of Yamaha exclusive features, including a fully automatic Ultramatic transmission, on command 2WD/4WD with diff lock, rear sealed wet brake, and more, all in a great handling package.

Just like the Grizzly 500 and 700, the 450 is a versatile middleweight ATV that rides on just about any surface. The design of the ATV may be utilitarian at first look, but it also offers plenty of serviceability, particularly the steel cargo racks that come with a special, extra-durable wrinkle paint finish with a combined cargo capacity of 264. The ATV also has a water-resistant, large-capacity underseat storage box; fully integrated floorboards with serrated foot pegs; large front and rear fenders with inner guards; dual, bright multi-reflector 30-watt Krypton bulb headlights with high and low beams; and a digital instrument panel that boasts a multifunction LCD display with speedometer, odometer, dual tripmeter, hour meter, 4WD status, transmission position, and clock.

Inside the Grizzly 450’s lightweight chassis is a 421cc liquid-cooled, SOHC four-stroke single engine that’s both rugged and powerful. The engine comes with a semi-oval slide 33mm BSR Mikuni carburetor and high-output
DC-CDI ignition capable of delivering fantastic throttle response and engine performance across all rpm. There’s also a large-capacity aluminum radiator that provides maximum cooling efficiency, positioned high in frame for optimal protection, and most importantly, Yamaha’s own Three-position On-Command In/Out 4WD feature that lets you switch between 2WD, limited-slip 4WD, and a fully locked differential 4WD.
