Supercharged! The Yamaha SR400 gets Kruggered

World champion bike builder Fred ‘Krugger’ Bertrand turns his hand to the Yamaha SR400, and the result is incredible.
The list of mods grows longer—and even more desirable—as you move to the cockpit. Behind the cowl is a tiny Motogadget speedo, along with switches and grips from the German company.

The handlebars are custom, and so are the foot controls—which have been machined to match the grips. The top triple clamp has been cleaned up. Beringer has supplied the front brake and hydraulic clutch, and Krugger has machined cutouts into the rear brake drum.

Krugger initially wanted the SR400 to be a little less ‘slick’ than his typical creations, such as the jaw-dropping BMW K1600 ‘NURBS.’ But when it was time to finish the SR400 off, he couldn’t help himself.

He prides himself on his “better than factory” reputation, and this project is no exception. The bike is laden with hidden details, like meticulously wound safety wire all over.

Blue is the color of MotoGP’s Bernard Ansiau, so Krugger has used a blue speedblock-inspired livery.

Look closely, and you’ll notice the names of all the racers Bernard’s worked with… from the above-mentioned superstars to riders like Randy Mamola, Norick Abe and Taddy Okada; and riders he admires, like Alain Chevalier.

Once again, Krugger’s obsessive level of work has blown us away.

Now hurry and find yourself a SR400…while you still can.

Krugger would like to thank: “Beringer, Dunlop, Wildhog for the saddle, Rokker protective equipment, J & Joy, and, of course Yamaha who trusted me. Also the men in the shadows: Adrien Jowa, my assistant, Thierry Dricot for photos and the décor, Vincent for paint, and 8185 Workshop for the ‘Forza Bernard’ laser etched plaque.”
