The Buell XB12 Lighting is quite unlike any other roadgoing motorcycle, though it draws a logical comparison with the Cagiva Xtraraptor and Ducati Monster. All three involve massive fuel-injected v-twin motors with minimalistic styling, but the Buell does it differently … very differently. For starters, it has 20% more engine capacity, and produces more torque delivered lower in the rev range than its competitors. The real trickery behind the Buell is not the engine though – it is the radical forged aluminium chassis. The fruit of countless hours of computer simulation of the stresses which motorcycle chassis’ undergo, it is as rigid as it looks, and doubles duty as a petrol tank, while the massive swinging arm also multi-tasks as the oil tank.
