Ironwood Custom Motorcycles get frequent requests for their signature R-Series BMW bobbers. But when a regular client rolled in with a unique donor, shop boss Arjan van den Boom knew he had to up the ante.
The bike in question was a 1982 BMW R100?but with a very special motor. It was packing a full Krauser upgrade, complete with four-valve heads, Nikasil barrels and an electronic ignition.

The client was a BMW and Porsche fanatic with very discerning taste. So whatever the Dutch shop built would need to be special.
Arjan and co. answered with a sharp, low-slung bobber that follows the typical Ironwood aesthetic, but with a slew of trick upgrades.

First, the boxer shed all of its 80s bodywork in favor of a more minimalist setup. Ironwood swapped the /7 fuel tank for a /5 unit, and added a solo seat with upholstery by Marcel from Miller Kustom Upholstery. They built a new pair of fenders too, with hand-made struts supporting them. Out back, the crew ditched the subframe and fabricated a new seat support and shock mounts. The BMW now sits on a pair of new rear shocks from TFX.

The front forks are Öhlins, lifted from an Aprilia Tuono. Ironwood kept the stock wheels, but wrapped them in modern, street-biased Continental Classic Attack tires. The front brakes were upgraded to Brembo units, with 320 mm discs for extra bite.
The highly tuned motor didn’t need any internal work, but on the outside it was cleaned up and re-done in black, with gold for the valve covers....
