Rotor locks have been around for many years and are one of the simplest and quickest ways to add an extra level of security when it comes time to walk away from your bike. There can be a few downsides to rotor locks, the most embarrassing and potentially harmful to you and your bike is forgetting to remove the lock before you ride.
Jaybrake has a great solution to the rotor lock downfalls with the RoadLoK Defender. The RoadLoK Defender is a billet bracket that mounts between the fork leg and caliper and incorporates a hardended stainless steel BrakeBolt locking pin that slides through the rotor locking it in place and preventing the bike from moving. Jaybrake offers the RoadLoK Defender as a bolt-on application for various H-D models from '84-present, '93-present Victory models, as well as many aftermarket rotors. The Defender is available in polish, clear satin anodize, and black satin anodize for $199.95, or chrome for $229.95.

Here is the bracket with the locking pin already in place (A). Just about the locking pin is the key hole (B). The Defender comes with two RoadLoK specific keys to prevent duplication. Also included is a plug to use in place of the locking pin while riding (C). |  2. Installation was really...  2.

Carl mentioned that in some applications it may be necessary to slightly bend or fuss with the brake line in order for the caliper to reach the new mounting position. |  5.

However, if you don't register your keys and you happen to lose them it will be very difficult to get new keys made. And no, you can't just go to your local locksmith, the keys are made from special blanks that come from one particular company. |  6. Here's how the locking...  6.

Oh, and for those who think you could just unbolt the bracket or cut the pin, the pin slides into the bracket housing on the backside of the rotor, basically making it impossible to unbolt or get at the pin with a cutting device. |  8.
