No helmet can protect the wearer against all impacts or injuries, nor is it possible to predict if a helmet will
protect you in any given accident. Head protection is complicated and is beyond the scope of this manual. The
function of the helmet is to reduce the chance or severity of a head injury in an accident. The helmet will not
protect the parts of your head that are not covered and will not protect your neck or spine from injury. It will not
protect you against head injuries that are not caused by impacts, such as shaking or vibration. For maximum head
protection, the helmet must be of a proper fit and the retention system [straps] must be securely fastened under
the chin. Failure to ensure a proper fit and securely fasten the helmet is dangerous as the helmet could come off
or slip into an improper position in an accident resulting in severe head or neck injury or death.

A helmet, like all products, may wear out over time depending upon its use and the amount of care that it is given.
Please check your helmet every time before use for damage and do not use a damaged helmet. Snell and Troy Lee
Designs recommend retiring a helmet after FIVE (5) years from purchase even if there is no visible damage or
defect. Of course with hard or frequent use this time may be reduced. Even with minimal use, a helmet is affected
by things like the acids and oils in sweat, hair care products, pollution, exposure to UV rays, corrosive dirt or mud,
being tossed around, etc. Of course, if your helmet becomes less than snug in fit, or damaged, it should be
replaced before the five year mark. Replacing your helmet every 5 years allows you to take advantage of advances
in helmet design and construction.

Helmets are designed to absorb ONE impact. After your helmet has
been involved in one impact you must destroy it and replace it. Your
helmet is designed to distribute the localized force of an impact
over a larger area on the helmet. Even if your helmet looks
undamaged its useful life is finished after one impact and will no
longer provide protection in an accident. With a sufficient impact,
the helmet's impact absorbing liner (EPS or "expanded polysty-
rene") becomes compacted. Once this has happened, the helmet no
longer has the ability to absorb further impacts and protect your
head. If you have any doubts for example, if you drop your helmet or
if it is hit by something and you are not sure if the impact was
sufficient to damage the helmet contact Troy Lee Designs before
you use the helmet again. Illustration depicts damage to the inner
EPS liner after an impact that may not be visible to the eye.
WARNING
GENERAL WARNINGS/SAFETY RECOMMENDATIONS
Never modify your helmet. It is very dangerous to drill holes or cut the shell and/or the shock absorption liner.
4
Modifications can seriously weaken the helmet. Modifying the retention system weakens it, and may render the
helmet useless in an accident. Removing parts such as the mouth guard or rubber face rim can expose edges,
which may injure you in an accident. Never sand or paint the outside of the helmet. Always use approved Troy Lee
Designs parts when replacing visors, screws, pads or any other part. A weakened helmet will not provide head
protection.
Always check your helmet before use. Check your visor screws and tighten if necessary. Check for cracks in the
5
helmet. If you find cracks or damage, stop using the helmet immediately. Plastic components may start to wear
out before 5 years from purchase. If you find deterioration in any part of a component, either replace that
component or get a new helmet. If these parts come loose and/or fall off while you're riding, your vision may be
blocked resulting in serious personal injury or death. Check the security of the retention system and always make
sure that the comfort liner and the cheek pads are attached before you use the helmet.
Do not purchase used helmets or any used parts for the helmet. Do not sell your helmet.
6
Do not wear anything between helmet and head.
7
Never allow others to use your helmet and do not use someone else's helmet.
8
Helmet may reduce hearing. Be aware of your environment.
9
Ride responsibly and do not take extra risks just because you are wearing a helmet.
10
11
Do not hang or hook your helmet on anything. It may cause damage to helmet reducing the effectiveness of
helmet's protection.
Do not drop your helmet on a hard surface. Doing so could permanently damage it. If unsure if you have damaged
12
the helmet contact Troy Lee Designs.
Never mount any rigid objects to the inside or outside of your helmet other than those sold by Troy Lee Designs.
13
This can weaken the helmet or cause injuries to you in an accident, by increasing the force on the helmet or the
object could become a projectile.
FOLLOW THESE 10 STEPS TO ENSURE A PROPER FIT
1
Fasten the chinstrap as tight as possible without causing you pain, restricting your ability to talk, or limiting your
ability to open your mouth or swallow freely. There must be no slack in the strap and it must be tight against your
neck.
2
Check whether the helmet inner lining fits snugly all around your head.
3
Check whether the top pad presses closely on the top of your head.
4
Check whether the cheek pads are in contact with your cheeks.
5
Check to make sure there is no space around your brow under the lining,
where you can insert your fingers.
6
With the chin strap secured, put your hands flat on the back of the helmet
and try and push the helmet off by rotating if forward. (See Fig. A)
7
Next, put your hands on the front of the helmet above your forehead (or on the chin guard)
and try and push the helmet off by rotating it toward the rear. (See Fig. A)
8
If the helmet starts to come off in either the forward or rearward direction, do
not use the helmet. Either the helmet is too large for you, or the chinstrap is not
tightened enough.
9
Now, take hold of the helmet with a hand on each side. Without moving your head,
try to move the helmet up, down and side to side. You should feel the skin of your
head and face being pulled as you try to move the helmet. (See Fig. B)
10
If you can move the helmet around easily, it is too big. Try a smaller size.
