Silver Lightning: Buell XB12S by M.A.M.

Buell Lightning XB12 Custom

A Buell V-twin by Motocyclettes Artisanales Minimalistes…

The Buell Lightning XB12S was introduced in the 2004 model year, sporting a fuel-injected 1203cc Thunderstorm V-twin that made an impressive 103 hp and a 84 ft-lbs of torque — more power than the alpha wolf of naked bikes at the time, the Ducati Monster S2R:

“If I knew absolutely anything about motorcycles and you would have shown me these two models one next to the other, I would be 100 percent certain that the bike called Monster is the one produced by Buell.” —Top Speed

What’s more, the XB12S boasted many distinctive Buell innovations, such as the highly-versatile chassis, fuel-in-frame design, perimeter front brake disc with six-piston caliper, under-engine exhaust, and more.

Enter François and Eric of Motocyclettes Artisanales Minimalistes (M.A.M.), located in southwestern France. The two have been friends since boyhood — more than 25 years. Their workshop’s stated mission is music to our ears:

“MAM project proposes to come back to what is most important (in our point of view): a beautiful bike, efficient and light, not only an exhibition object.”

Last year, we featured their stunning Yamaha XT600 Retro Motard — a short-wheelbase, 264-pound supermoto built to go as well as it looks. Now they’re back with this 2004 Buell XB12S, built for a client who gave them free rein in terms of design. All of the bodywork has been custom-made in aluminum, including the tail, airbox, fenders, headlight, brackets, and more — more than 600 hours of work, and the transformation is completely reversible!

Below, we get more details on this striking, aluminum-clad Buell!

  1. That is a wicked looking build very creative. What is fuel capacity?

    • a capacidade volumétrica do tanque não se altera; o modelo da Buell possui o tanque integrado ao chassi da moto, ou seja, o chassi é oco. Sendo na versão XB12S 14,5 litros e 16,7 litros na versão XB12SS ( long). O que foi modificado é apenas uma caixa de ar ( que fica instalada onde costumamos observar o local do tanque de combustível em outras motos).
