Overview
When Buell decides to play the disruptor in the urban streetfighter segment, the result is something rather difficult to categorize. The XB-12 SX Lightning City Cross 2010 is exactly that: a machine that refuses labels, built on the XB-9S X platform but muscled up a notch with the Thunderstorm twin bored out to 1203cc. On paper, that translates to 94 horsepower at 7000 rpm and 102 Nm of torque available from 5500 rpm. At 179 kg dry, the mechanical density is very real.

What strikes first is the architecture. Buell has always done things differently, and this XB-12 SX is no exception. Fuel travels inside the aluminum perimeter frame, oil lives in the swingarm, and the single front brake disc is a 375 mm perimeter unit mounted at the wheel's edge. A system that baffles at first glance but concentrates mass in a radical way. The 43 mm inverted fork, with a shallow rake combined with a short wheelbase, delivers incisive steering that Japanese streetfighters of equivalent displacement sometimes struggle to match in urban agility.
The City Cross trim makes no apologies. Tall wide handlebars, hand guards borrowed from the adventure world, a headlight guard, and translucent screen and tank that let you glimpse the machine's inner workings. It's deliberately hybrid — somewhere between a supermoto that spent too much time in the city and an urban adventure bike that never left the tarmac. You either love it or hate it, but it looks like nothing else on the 2010 market. Facing a Ducati Hypermotard 796 or a KTM 990 SM, the Buell plays the card of radical originality rather than outright performance.
The limitations are well known. The 5-speed gearbox is one ratio short on the highway, the claimed top speed of 200 km/h will never be the main selling point of this short and nervous package, and the asking price of €11,395 makes it a choice for enthusiasts rather than a calculated purchase. The 14.5-liter tank offers adequate range without being exceptional. This is not a motorcycle for the undecided or for riders seeking quiet everyday versatility.
The XB-12 SX City Cross targets a specific audience: the urban rider who wants something sharp, distinctive, and who accepts sacrificing long-distance comfort on the altar of immediate pleasure. It isn't a new model in the strict sense — more a logical evolution of the XB-9S X with the bigger engine under the frame. But in the often consensus-driven world of naked bikes, this Buell remains a genuinely singular proposition, driven by a Harley-Davidson engine that knows how to make itself heard when asked.
