2013 Yamaha Grizzly 550 FI Auto 4x4 EPS

Posted on by  

Big, reliable and strong, the Yamaha Grizzly 550 FI is a capable ATV that is able to tackle a wide variety of terrains with poise.

At the heart of this four wheel beast lies a 558cc, 4-stroke, SOHC 4-valve liquid-cooled engine derived directly from the industry-leading Grizzly 700 powerplant. The engine is linked to a stainless steel exhaust system that features aluminum heat shields and a screen-type spark arrestor. The power is sent to the ground through Yamaha’s Ultramatic fully automatic transmission.

For increased versatility there is available a three-position On-Command In/Out 4WD feature that lets you switch between 2WD, limited-slip 4WD and fully locked differential 4WD.

The ride quality is kept in check by a fully independent long-travel four-wheel suspension that features double-wishbone suspension front and rear with five-way preload-adjustable shocks.

The ATV is available at a starting price of $9,149.
