2012 Yamaha Grizzly 550 FI Auto 4×4 EPS Review
Voted “Best of the Best”…
The Grizzly 550 EPS sets the bar and tops the sales charts with industry-leading durability and reliability.
With all the features of its big bore brother including industry first electric power steering (EPS) bit in a slightly smaller engine package, the 2012 Yamaha Grizzly 550 FI EPS is the ultimate utility AT and Field & Stream’s “Bset of the Best.”
The 2012 Yamaha Grizzly 550 FI packs all the same great features as the 2012 Grizzly 700 FI and it’s powered by a 558cc engine. That makes the Grizzly 550 just about the perfect balance of performance, features and price.
At the heart of the Grizzly 550FI EPS SE, you’ll find a powerful 558cc, four-stroke engine with fuel injection that delivers plenty of power, and makes cold starting a breeze.
The long-travel four-wheel independent suspension serves up awesome ground clearance to get up over and around the gnarliest terrain. While the bush button On-Command system will have you in complete control, simply select the 2WD, limited-slip 4WD or Diff-Lock 4WD to suit the terrain. Yamaha’s Electric Power Steering, Ultramatic Transmission and disc brakes at every wheel round out this awesome middleweight ATV, without breaking the bank.
2012 Yamaha Grizzly 550 FI Auto 4×4 EPS Highlights:
