keeping your
battery charged.
New design wet
multi-plate rear
brake improves
braking feel and
performance.
New rear gear
assembly with 3
point mounting
contributes to
frame rigidity.
Quality that goes more than skin deep.
Discover the Yamaha difference...
The new one piece frame
resists flexing, allowing
the fully independent
suspension to do its job,
absorbing bumps without
upsetting the machine’s
balance, resulting in even
better handling.
Yamaha’s patented, speed
sensitive Electric Power
Steering system (EPS)
helps improve comfort by
lessening the handlebar
t turning force, reducing
r rider effort and fatigue
f for longer days at work.
Ultramatic transmission
means no gear changing
and instant power when
you need it. The V-Belt
is quiet and reliable. Full
downhill engine braking
in 4WD is provided to all
four wheels on descents.
A new 322w high output
AC generator gives 39%
more charging at mid
rpm, ensuring that battery
power is available for
the EPS and accessories.
Engine width is reduced
giving more legroom.
The sealed multi-disc rear
brake operates in its own
oil bath and provides
stopping power even in
the worst conditions. The
new top mount linkage
further improves weather
protection and durability.
The IRS mounting is now
significantly stronger with
the new gear case’s three
point fixing adding rigidity
to the one-piece frame.
Exhaust system is made
from Stainless Steel to
resist corrosion.

Multifunction LCD digital instrument
panel includes diagnostic function.

ATVs with engines up to 70cc are recommended for use only by riders 6 years and older and always with adult supervision. ATVs with engines of 70 to 90cc are recommended only for use by riders 12 years and older, and always under adult
supervision. ATVs with engines of 90cc or greater are recommended for use only by riders 16 years and older. ATVs are built to operate within their design limits. Safe towable weights, together with maximum carrying capacity are identified in
the owner’s manual if applicable. For durability, reliability, but most important of all, operator safety, under no circumstances should the recommended capacities be exceeded. Yamaha recommends that all ATV riders take an approved training
course. For safety and training information, see your dealer or call your Yamaha Distributor in your country. ATVs can be hazardous to operate. For your safety: always avoid paved surfaces. ATVs are designed for unpaved surfaces only. Riding
on paved surfaces may seriously affect handling and control and can cause loss of control. Always wear a helmet, eye protection and protective clothing. Never carry any passengers. Never engage in stunt riding. Riding and alcohol/drugs don’t
mix. Avoid excessive speed and be particularly careful on difficult terrain. Please ‘tread lightly’: always ride in a responsible manner, respecting the environment as well as country and local laws. The riders in this brochure are professionals: don’t
attempt to emulate them. The specification and appearance of Yamaha products will be varied from time to time without notice, and as shown here are illustrative only and are not a contractual description of products. Some models are shown
with optional accessories. All ATVs come with a 12-month Limited Factory Warranty, except for Banshee, which carries a 90-day Limited Factory Warranty. See your dealer for details.
