The old man of the group, the Star sports an air-cooled engine and five-speed transmission, which along with the hidden shocks and bubbly 16-inch wheels, harkens back to well, the 90s. Though the Road Star family gained EFI and a few extra cubes a few years back, it's definitely showing its age. But that's not always a bad thing with cruisers, as that kind of stability allows the aftermarket to produce all kinds of goodies for a bike, something the two youngsters will have to earn over time. At just a year old, Kawasaki's Vulcan Classic LT is the next oldest bike. The Vulc has a liquid-cooled engine and 6-speed transmission, sports a thick-tire stance, and is embellished with studs on its leather and two-tone paint on its sheet metal. Triumph's Thunderbird is the newcomer. Introduced as a late-release 2010, the T-Bird SE fills a niche that hasn't been seen in awhile; a custom/sporty cruiser with 'boards and bags, rather than a "classic". Like the Kawasaki, it runs a liquid-cooled DOHC engine and six-speed transmission, but deviates from the others with a parallel configuration to its twin cylinders. Not to worry, it's still got that lumpy V-twin sound.
