I went ahead and ordered the lock from Motorcycle Superstore. They seem to have a generous return policy in case it doesn’t fit. I also went on the Xena website, thanks mhl, and found that they do indeed have a section that lists what bikes the lock will fit.
Finally, I live in the southwest by a border. Stolen cars and bikes here are as common as rain is in the northwest. I personally know 3 people that have had thier bikes stolen in the last couple of months. I know that there are no devices that will stop a theft 100% of the time but I figure I will make it as hard for them as I can. I try to lock my bike down to an inmovable object but this is not always possible. For now I will use the brake disk lock in conjunction with a u lock. Thanks again all.
