Three-wheelers have designs on sportiness, safety

Used to be that a three-wheeled motorcycle, or trike, meant one wheel in front, two in back. Then Can-Am sped onto the market with its snowmobile-esque Spyder, a three-wheeler that gave the segment a sporty makeover by putting the two wheels out front. In the year since the Spyder's unveiling, the three-wheeled segment is growing faster than a center fielder on steroids, with a number of new models coming to market throughout 2008. We take a sneak peek at the year's three-wheeled future.
