Within the Yamaha family of utility ATVs, the Grizzly
stood steadfast as the king of the forest for years. Industry-leading
features coupled with top-of-the-line quality and the
plush ride Yamaha is known for, made the Grizzly an unbeatable
choice for any customer looking for an ATV just as capable
for work as it is for play. Fast forward to 2007 and you
see that the all-new Grizzly 700 will continue to reign
supreme as it ups the ante with updates and never before
seen ATV technology added to its already perfect pedigree.
2007 Yamaha Grizzly 700 FI 4x4
The Reign of Supremacy Continues
For 2007 the Grizzly 700 leads the chase in the department
of technology. Sure, it continues to feature Yamaha
exclusives such as the proven Ultramatic® automatic
transmission system and On Command® push-button
four-wheel drive system, and now the all-new Yamaha
Fuel Injection system (YFI) system, but the icing on
the cake is the industry-first EPS…Electric Power
Steering. Yes, you read that correctly, EPS on an ATV
- talk about plush!
The Yamaha Electric Power Steering system is unparallel
in the industry. The system allows the rider to tackle
the most gnarly, toughest terrain with the least amount
of effort, rider fatigue and superior comfort. How, you
ask? As the rider turns the handlebars the electric motor
kicks in and assists in the turn. The harder you turn,
the more the EPS assist. The torque-sensing EPS system
senses the twisting force put on the handlebars and wheels
at which point the electric motor jumps in to do its thing.
Best part is, not only does the EPS offer light steering
effort, but it also absorbs the kickback that would usually
be transferred to the rider if you were to hit a log or
Industry-exclusive: Electronic Power Steering
(EPS) system lightens steering and helps ease
kickback, for superior comfort and terrainability.
Although the EPS system attempts to steal the spotlight,
the additional changes to the Grizzly 700 round out
an amazing all-new machine. The new Grizzly 700 powerplant
moves from 660cc to 686cc, and is adapted from Yamaha’s
leading sport ATV, the Raptor 700R, which gives the
Grizzly a sportier, fun ride even with the engine tuned
for true utility use. Of course, those extra 26cc also
mean additional power throughout the entire rev range
– most notable is the enhanced low- to mid-range
Moving down the laundry list of updates to the engine
you’ll find a new forged piston for reduced weight
and added durability, while a new aluminum cylinder body
with composite coating offers reduced weight, increased
cooling ability and additional wear resistance. The new
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.
Of course, the ultra-convenient electric start feature
continues to make firing the liquid-cooled, four-valve
SOHC powerplant to life a snap.
Raptor-based four-valve combustion chamber design
produces a potent combination of low-rev torque,
right-now throttle response and high horsepower.
Ceramic-composite cylinder liners provide outstanding
durability and heat dissipation; forged piston
is light and strong and rides a carburized, chrome-moly
Delivering all that power is the Ultramatic automatic
transmission system, with reverse, of course. The transmission’s
gearing ratio has been revised, optimizing the additional
power and making full use of the powerband under a variety
of riding situations. Reverse is also re-geared for
easier operation. The Grizzly 700 offers the convenience
of high- and low-range gear options for times when low-end
torque and maximum pulling power are needed. The shift
lever is conveniently located on the left side, and
the other gear options include parking, neutral and
fully automatic Ultramatic® transmission is
the most advanced drive system in ATVing. An automatic
centrifugal clutch maintains constant belt tension
for reduced belt wear and industry-exclusive all-wheel
downhill engine braking.
The all-new gate shifter gives an improved shift feeling,
allowing the rider to easily see what gear he has selected.
Of course, this is also easy to see on the redesigned
LED display, which offers dual trip meter, speedometer
and odometer in addition gear selection, fuel level
indicator, On Command indicator and EPS and fuel injection
indicator lights. The EPS and fuel injection indictor
lights let the rider know when the systems need to be
serviced per the self diagnostic system.
The Yamaha Fuel Injection system (YFI) finds its way
to the Grizzly 700 after the spectacular debut it made
on the Raptor 700R last year. The YFI improves throttle
response throughout the powerband, helping the rider
take advantage of that improved 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 means clean power delivery, better throttle
response and improved fuel economy under a multitude
of riding situations. In addition, YFI means no choke
and easier cold starting, which is great for those early
morning hunts or chores around the farm.
The three-way On-Command system featuring push-button
2WD/4WD and 4WD with differential lock is the perfect
compliment to the Grizzly 700 powerhouse. Located on
the right handlebar, the push-button is at the rider’s
fingertips to command all four wheels as the terrain
shift lever with H, L, N, R and P gates for positive
Ultramatic trans operation.

as well as bar-type fuel gauge, odometer, tripmeter,
clock and Diff Lock indicator
The Grizzly 700 also features major changes to styling,
many of which are a direct result of changes made to
improve handling, make serviceability a breeze, centralize
mass and give the vehicle a lower center of gravity.
First off is the relocated air box, which moves from
under the seat to the top of the engine. This change
means easier access and service for the rider and the
higher intake location will be much appreciated by those
riders that are fond of deep water crossings. The fuel
tank has also been relocated and is now found mostly
under the seat as part of the mass centralization and
to lower CG. The new fuel tank features a ratchet-type
cap for improved quality feel.
Moving on down the body of this beast we find a fully
independent wishbone front and independent rear suspension
(IRS) – adjustable in front and rear – offers
the rider the versatility to set-up the ATV for all
riding conditions. Featuring 7.1” of travel up
front and a class-leading 9.5” in the rear, the
Grizzly 660 is ready to tackle just about any terrain.
What’s more, 11.8” of ground clearance makes
it an unrivaled trail performer. The most noticeable
change here is a redesign to the shape of the front
and rear A-arms. This slightly rounded new shape offers
additional ground clearance. Again helping achieve the
low CG feel, the suspension has found new mounting points
on a lower part of the frame and lower A-arms.
As if one industry first with EPS wasn’t enough,
Yamaha has added a little something extra to the brakes
as well with four-wheel hydraulic disc brakes. Most
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 2007 Grizzly 700, brake calipers
are coupled to each wheel individually along with a
new brake master cylinder front and rear for unmatched
braking feel and power.
independent long-travel four-wheel suspension
features WideArc front A-arms and rear-swept A-arms
out back for maximum ground clearance. Preload-adjustable
shocks mean maximum control and comfort over rough
The Grizzly 700 also features all-new ground-grabbing
meats mounted to aluminum wheels to get you moving.
The all-new Dunlop tires feature a new tread pattern,
exclusive to Yamaha for improved traction and rider
On the side of comfort and durability, we find the Grizzly
700 boasting a 32mm thicker seat and redesigned, larger
floorboards for even more protection from the elements.
The new design of the floorboards also allow for better
drainage of mud and water. Two storage boxes – a
redesigned under seat box and an all-new box 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 lbs. and 187 lbs. of carry capacity
on the front and rear racks, respectively and the 1,212
lbs. of towing. And, a new SecureMount rack system has
been developed to offer superior fit and finish with Genuine
Yamaha Accessories, which were designed in tandem with
the rack system.
