DISC LOCK ONLY
Use of the disc lock can help prevent roll away theft. When using a pin-style disc lock, place the pin through a hole in the rotor. When using a shackle style disc lock, place the shackle towards the center of the disc brake if possible.
CHAIN OR u-lock
When using your primary lock, whether it be a chain or u-lock, it is important to capture both the immovable object, and the frame of the ATV/UTV. When on the trail, securing 2 ATV/UTV's together by capturing both frames is a good idea as well.
For maximum protection, Kryptonite recommends using two locks: a disc lock to prevent roll away theft, as well as a chain or u-lock to an immovable object to prevent lift away theft. Make sure the chain or u-lock is capturing the frame of the ATV/UTV.
