Can-Am Spyder Roadster: Poetry

I saw two guys riding Spyder Roadsters last night — it was too dark to get pictures — and I was amazed. These are three-wheel motorcycles with two articulated wheels up front and a powered wheel in back. They were hitting about 60 MPH running alongside us and when they went to pass they literally looked like Storm Troopers on Speeder Bikes. The entire frame articulates slightly at high speeds, giving them an incredible boost. Has anyone ridden one? Care to share the experience?
