Quick and easy to use! Disc locks provide motorcyclists and other power sports users outstanding security in a small convenient size. Offer great protection against drive off thefts and easily fit in a pocket or tank bag. Comes with carrying case and orange disc reminder cable to prevent accidental drive aways. Fits on brake discs with either slots or minimum 10mm (?) drilled holes. I used it on my VFRs and GoldWings. Fits many other models. The orange reminder cable goes up around your handlebar to remind you not to drive off before removing the lock! Complete with 4 original keys.
