I've seen an odd looking motorcycle in the area over the past few weeks. It has three wheels, one in the back and two in the front.
I got a good look at it cornering the other day. It appears to have some sort of front suspension linkage that keeps both front wheels on the ground and parallel to the body of the bike as it leans. This is unlike an automobile suspension, where the wheels (particularly the outside wheel) is kept at right angles to the pavement as the body rolls.
What is it? And an even more interesting question: Why is it?
