2012 Yamaha Grizzly 550 FI Auto 4×4 Highlights:

Key selling points:

package based on its best-selling bigger brother,
the Grizzly 700 FI, with a largest-in-class 558cc
powerplant and excellent value.

lets you switch between 2WD, limited-slip 4WD and
fully locked differential 4WD-all with a simple
push of a button.

features double-wishbone suspension front and
rear with five-way preload-adjustable shocks for
maximum control and comfort over rough terrain.
Smoothest-running and -riding Grizzly ever.

Trick digital instrument panel boasts a
multifunction LCD display with speedometer,
odometer, dual tripmeter, hour meter that counts
the engine’s running hours, 4WD status,
transmission position, clock and fuel gauge.

class at only 648 pounds wet weight.

flawless fuel delivery in nearly any condition, from below sea
level to 15,000 feet.

assembly to protect the starter motor.

and a screen-type spark arrestor for great power with minimum
noise output.

whatever the load or trail conditions.

typical rubber boots.

centralization and handling; there’s a 4.8-liter water-resistant
storage compartment under there, too.
o 11.8 inches of ground clearance and full-length composite
skidplate deliver maximum underbelly protection while
enhancing terrainability.
