Cool. A guy here in town takes his slightly larger dog with him in a plastic milk crate,(Can be had at wal-mart) strapped to the luggagge rack on the back. Years ago a had a very small rat terrier who liked to go while zipped in my leather jacket, with just his head sticking out! If I had to do it again, I would build a special pad on the tank and make a short leash wherin he/she could stand and sit in front of me, while tethered to me to stop him/her from falling off. A bit of training, that.
