I live in Pittsboro, NC, and use my Suzuki GR650X Tempter to commute between home and college. The problem is, my college is located in eastern Durham, which isn't exactly the safest or most secure.
What I need is a disc lock. I bought an OnGuard 5.5mm lock at a dealership, but the peg proved just barely too big to use. I could force it through the hole in the brake disc, but the button wouldn't go in all the way and click shut. My guess is I need a 5mm lock. Any suggestions?
