CYPRESS, Calif. – June 6,
2008 – Yamaha Motor Corp., U.S.A.,
revolutionized the off-road industry with the
world’s first Electric Power Steering (EPS) in
an ATV and is now making that technology
available again in the all-new Grizzly 550 FI.
Yamaha expects the Grizzly 550 FI to dominate
the popular 500-600cc class just as the Grizzly
700 FI has done in the big bore category.
The new mid-sized utility ATV takes all of the
consumer-favorite features -- the groundbreaking
technology of EPS, the comfort, terrainability
and toughness -- found in the company’s flagship
Grizzly 700 FI and incorporates them into a
machine with a slightly smaller engine. The 550
not only meets customer requests for a 500- to
600-sized model, it exceeds expectations by
featuring all the bells and whistles that adorn
the Grizzly 700 FI.
"Power steering has been a huge success and has
helped make the Grizzly 700 FI the best selling
big bore utility ATV on the market today*,” said
Steve Nessl, Yamaha’s ATV/SxS marketing manager.
“We’re excited about the Grizzly 550 and expect
it to make a major impact on the utility ATV
market. The 550 essentially combines the
features of the award- and shootout-winning 700
with a slightly smaller engine and a
value-packed price tag.”
The Grizzly 550 FI is jam-packed with the
features and benefits customers have come to
expect from Yamaha, starting with reliable power
from the 558cc liquid-cooled, four-valve SOHC
engine. As on the Grizzly 700 FI, the 550
features a forged piston for reduced weight and
added durability, while an aluminum cylinder
body with composite coating offers reduced
weight, increased cooling ability and additional
wear resistance. The roller rocker arms reduce
friction in the valve train, which allows the
engine to rev more freely leading to better
overall performance and improved throttle
response. The Grizzly 550 also receives an
all-new cylinder head for improved throttle
response and bottom end power.
The Yamaha EPS system is unparalleled in the
industry and has received numerous awards and
praise from customers. As the rider turns the
handlebars and the torque- and speed-sensing EPS
system senses the twisting force put on the
handlebars and wheels, the electric motor kicks
in and assists in the turn. The harder the rider
turns, the more the EPS assists allowing the
rider to tackle the toughest terrain with the
least amount of effort.
Although the EPS system is definitely a favorite
feature, the Grizzly 550 FI is also offered
without power steering and starts at
approximately $700 less (MSRP) for the
budget-minded customer.
The Yamaha Fuel Injection system (YFI) improves
throttle response throughout the powerband,
helping the rider take advantage of the low- to
mid-range power. YFI offers unmatched
performance at high elevation as the system is
able to detect and compensate for changes in
altitude. The more precise fuel delivery offered
by the YFI makes consistent power, better
throttle response and improved fuel economy
under a multitude of riding situations. In
addition, YFI means no choke and easier cold
starting.
Also gracing the Grizzly 550 FI is Yamaha's
industry-exclusive Ultramatic™ automatic
transmission system. The transmission’s gearing
makes full use of the powerband under a variety
of riding situations, and the automatic
centrifugal clutch maintains constant belt
tension for reduced belt wear and
industry-exclusive all-wheel downhill engine
braking. The shift lever is conveniently located
on the left side, and gear options include high,
low, park, neutral and reverse.
An all-new open gate shifter -- updated from the
shifter found on the 2008 Grizzly 700 FI --
allows the rider to easily see what gear he or
she has selected. This is also easy to see on
the LCD display, which offers dual trip meter,
speedometer and odometer in addition to gear
selection, fuel level indicator, On-Command™
indicator, and EPS and fuel injection indicator
lights. The EPS and fuel injection indicator
lights let the rider know when the systems need
to be serviced according to the self diagnostic
system.
The three-way On-Command system, featuring
push-button 2WD/4WD and 4WD with differential
lock, compliments the Grizzly 550 FI powerhouse.
Located on the right handlebar, the push-button
is at the rider’s fingertips to command all four
wheels as the terrain dictates.
The Grizzly 550 FI offers other "extras" that go
a long way in making this machine durable and
provide added convenience to the rider. The air
intake is located on top of the engine allowing
for easier access and service as well as helping
to keep water and other debris from entering the
air box. The CVT air intake and exhaust ducts
are also centrally located and mounted to help
reduce the possibility of debris and water
entering the transmission system. New A-arm
guards cover more surface area, which increases
protection of vital components while a new,
improved CV boot material gives better
resistance to tearing even when battling the
nastiest of elements.
The fuel tank is placed under the seat for
maximum centralization of mass. The front and
rear shocks are mounted lower on the A-arm
compared to competitive models, which improves
the low center of mass feeling.
Fully independent wishbone front and independent
rear suspension (IRS) ensures optimal traction
and terrainability from the Grizzly 550.
The adjustable suspension in both the front and
rear offers the rider the versatility to set-up
the ATV for all riding conditions. Featuring 7.1
inches of travel up front and a class-leading
9.5 inches in the rear, the Grizzly 550 FI is
ready to tackle just about any terrain. What’s
more, 11.8 inches of ground clearance makes it
an unrivaled trail performer. The Grizzly 550 FI
also features the Yamaha-exclusive WideArc front
suspension, which offers five inches of more
useable ground clearance in front.
Another popular feature found on both the 700
and now the 550 is the class leading four-wheel
hydraulic disc brakes. Most full-featured models
see three discs, two up front and one on the
rear axle, which controls braking for both rear
wheels. In the case of the Grizzly 550 FI, brake
calipers are coupled to each wheel individually
for unmatched braking feel and power.
The Grizzly 550 FI also features ground-grabbing
tires mounted to aluminum wheels to get you
moving. The Dunlop tires feature a
Yamaha-exclusive tread pattern for excellent
traction and rider comfort.
On the side of comfort and convenience, the
Grizzly 550 FI boasts a thick, plush seat and
full floorboards for protection from the
elements along with an all-new throttle lever
shape. Two storage boxes -- one under the
seat and another found in the right front fender
-- offer plenty of storage in a sealed,
waterproof and water-resistant space. This is of
course in addition to the 99 pounds and 187
pounds of carry capacity on the front and rear
racks, respectively, and the 1,322 pounds of
towing capacity. The SecureMount rack system
offers superior fit and finish with Genuine
Yamaha Accessories, which were designed in
tandem with the ATV.
The Grizzly 550 FI EPS will be available at
Yamaha dealerships in August 2008. Models
are available in Black Metallic, Hunter Green
and Steel Blue with an MSRP of $7,799. A
Special Edition in Red Midnight Armor (MSRP
$8,399) and a Hunter Edition in Realtree™ AP HD®
Camouflage (MSRP $8,199) will also be out in
August. The non-EPS model will be available in
Black Metallic, Hunter Green and Steel Blue
(MSRP $7,099) and a Hunter Edition version will
also be available in Realtree™ AP HD® Camouflage
(MSRP $7,499) at Yamaha dealerships in October
2008.
