INITIAL FIT
Grabbing one chinstrap in each hand, gently pull each strap outward and the pull the helmet over your
head. Gently shake your head to the right and to the left. Then shake your head forward and back, or
try to turn the helmet with your hands. Rotating the helmet from side to side, observe the movement
of your skin in relation to the helmet. The initial helmet t is correct when skin movement and helmet
movement are nearly the same. If it slips in any direction easily, try the next size down.
CHIN STRAPS
Position the chinstraps underneath your chin, towards your neck, and secure the buckle. Tightly fasten
the chin strap by pulling it comfortably tight for a secure and snug t. The chinstrap should be as tight
as possible, but without causing pain. Move your head up and down and side-to-side to ensure that the
strap does not interfere with your ability to breathe, talk, swallow or turn your head. If so, re-adjust the
straps. Make sure the strap and strap covers are at against your skin and are not twisted or bunched in
any way.
FINAL FIT
With the buckle secured and chinstrap properly and securely fastened, check for the nal t. Grab
the front of the helmet, push up and rotate the helmet to the rear. Then lift up rmly on the rear of the
helmet, push forward and try to rotate the helmet off. You should not be able to remove the helmet from
your head while doing either of these steps. If you can remove the helmet or if it slips in any direction
easily, try the next size down.
With the straps property fastened, you should not be able to pull the helmet off of your head in any
direction.
IF THE HELMET STILL DOES NOT FIT PROPERLY AFTER THE ABOVE STEPS. DO NOT USE THE
HELMET. Replace it with a different size or a different model. Failure to do so may result in serious
injury or death in the event of an accident. To ensure the continued proper t of this helmet, you should
check the t during the course of riding and every time it is worn and adjust as needed. To ensure max-
imum safety, the helmet should be t by trying several different sizes on and choosing the size which
feels secure and comfortable on the head.

and destroyed. The original components of this helmet should not be modied or removed, other than as
