I have had a bike track for the last 4 years, great product, and there is a very neat and suitable place to fit it to the XR, as well as what norskman says the website tracking option is great, you can see a detailed journey history broken into segments, every time you turn off the ignition, these segments can be downloaded in gpx format to load into your satnav or basecamp, or its just good to be able to look where you've been and it can also display your speed at any given point on the route.
Having Biktrac that will send an SMS immediately to you if its moved without the ignition being switched on and will track it may just result in the "little scrote that nicked it" getting jail time, potentially recover more stolen bikes and stop other fellow bikers suffering a similar fate!
