2008 -Buell-LightningSuperTT XB12STT = The Lightning Super TT brings Supermoto-inspired styling and performance to the street. A narrow-and-flat solo seat makes it easy to move and set up for the next turn. Wide, flat handlebars provide outstanding leverage and centered foot peg placement puts the rider in an athletic position. The clipped, black cast-aluminum tail section shows off the 180 mm rear tire. White number plate side panels and flyscreen add a competition look, and are designed to be personalized and are easy to change. Fork slider protectors, handlebar deflectors, cosmetic frame protectors, a high front fender and headlight grille protect the Super TT from the abuse of the street. The 54-inch wheelbase gives the rider room to work, but retains that trademark Buell agility, while 6.25 inches of suspension travel keeps the Super TT well-planted on rough pavement.
