Never tried it myself but I live in a small town the motorcycle police uses as a training facility. Next to my house is a one story staircase to the main shopping street and I see them driving up and down this staircase, which is not very wide, every month. They do it on BMW RT's, mainly they use 850's of some years ago for training new cops.
Now I ride with some officers in my club, and some of them are very experienced riders, but I also see a lot of police riders that make me think, maybe you should get some training.
