ples include (but are not limited to) a heavy or
bulky object attached to the handlebars which
could make steering difficult, an accessory that
limits your ability to move around on the seat, or
one that limits your view.

Use extra caution when riding an ATV with ac-
cessories. The ATV may handle differently than
it does without accessories.
EBU21081
Loading
WARNING

EWB00820
Never exceed the stated load capacity for this
ATV. Overloading this ATV or carrying or tow-
ing cargo improperly could cause changes in
ATV handling which could lead to an accident.
Cargo should be properly distributed and se-
curely attached. Reduce speed when carrying
cargo or pulling a trailer. Allow greater dis-
tance for braking.
As originally equipped, this ATV is not designed to
tow a trailer. If you choose to add accessories so
that you can tow a trailer, you must use common
sense and good judgment as the stability and han-
dling of an ATV can be changed. When adding ac-
cessories, keep the following points in mind:

Never exceed the weight limits shown. An over-
loaded ATV can be unstable.

If you are carrying cargo and towing a trailer, in-
clude the tongue weight in the maximum ATV
load limit.

Load cargo on the carriers as close to the center
of the ATV as possible. Put cargo at the rear of
the front carrier, at the front of the rear carrier,
and center it.

Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.

Make sure the load does not interfere with con-
trols or your ability to see where you are going.

Ride more slowly than you would without a load.
The more weight you carry, the slower you
should go. MAXIMUM LOADING LIMIT
ATV loading limit (total weight of rider, cargo,
accessories, and tongue):
105.0 kg (231 lb)
Front carrier:
5.0 kg (11 lb)
Rear carrier:
10.0 kg (22 lb)

GETTING TO KNOW YOUR ATV
This ATV is for recreation and utility use. This sec-
tion, Riding your ATV, provides general ATV riding
instructions for recreational riding. The skills and
techniques described in this section, however, are
appropriate for all types of riding. Riding your ATV
requires special skills acquired through practice
over a period of time. Take the time to learn the ba-
sic techniques well before attempting more difficult
maneuvers.
Riding your new ATV can be a very enjoyable ac-
tivity, providing you with hours of pleasure. But it is
essential to familiarize yourself with the operation
of the ATV to achieve the skill necessary to enjoy
riding safely. Before you begin to ride, be sure you
have read this Owner’s Manual completely and un-
derstand the operation of the controls. Pay partic-
ular attention to the safety information on pages
2-1–2-4. Also read all warning and notice labels on
your ATV.
RIDE WITH CARE AND GOOD JUDGMENT
Get training if you are inexperienced.
WARNING

EWB01381

Do not operate this ATV or allow anyone else
to operate it without proper instruction. The
risk of an accident is greatly increased if the
operator does not know how to operate the
ATV properly in different situations and on
different types of terrain.

Do not operate this ATV at speeds too fast
for your skills or the conditions, as this in-
creases your chances of losing control of
the ATV and an accident. Always go at a
speed that is proper for the terrain, visibility
and operating conditions, and your experi-
ence.
Beginning and inexperienced operators should
regularly practice the skills and the operating tech-
niques described in this Owner’s Manual.
Riding your ATV requires skills acquired
through practice over a period of time.
Do not attempt to operate at maximum perfor-
mance until you are totally familiar with the ATV’s

handling and performance characteristics. Take
the time to learn the basic techniques well before
attempting more difficult maneuvers. Become fa-
miliar with this ATV at slow speeds first, even if you
are an experienced operator.
Not recommended for children under 16 years
of age.
WARNING

EWB01390
A child under 16 should never operate an ATV
with engine size greater than 90 cc. Use by chil-
dren of ATVs that are not recommended for
their age can lead to severe injury or death of
the child.This ATV is designed to carry the operator
and cargo only – passengers prohibited.
The long seat is to allow the operator to shift posi-
tion as needed during operation. It is not for carry-
ing passengers.
WARNING! Never carry a
passenger. Carrying a passenger on this ATV
greatly reduces your ability to balance and
control this ATV. You could have an accident,
resulting in severe injury or death to you and/
or your passenger.

event of an accident.
[EWB01411]
Wear eye protection when operating your ATV to
