The Buell X1 Lightning represents a significant leap forward in Erik Buell’s pursuit of high-performance motorcycles. This Wisconsin-based engineer has been perfecting his craft for over a decade, and it shows in every aspect of the X1.
With its sleek new styling, refined engine character, and improved ergonomics, the X1 is a far cry from its eccentric predecessors. Gone are the oversized air filters and truck-like exhausts; instead, the X1 boasts a smaller air filter, belly pan, and larger seat for increased comfort on long rides.
But it’s what’s under the hood that truly sets the X1 apart. The air-cooled V-twin engine has been tweaked to perfection with Buell’s ‘Thunderstorm’ cylinder heads, delivering an impressive 95bhp at 6200rpm. Coupled with a new fuel-injection system, this powerhouse of an engine provides effortless acceleration and smooth power delivery.
The result is a bike that not only looks stunning but also handles like a dream. With its stiffer steel frame, new aluminum subframe, and Showa suspension, the X1 Lightning is capable of reaching genuine speeds of 140mph (225km/h).
