RSWB: A Granada Purple Toaster Tank BMW by Roughchild

There aren’t many new methods left to customise traditional R-series BMWs, and which means it’s tougher to make them stand out. You both must construct one thing wild or, like Roughchild Bikes of Los Angeles, maintain it easy… and intensely tasteful.

Based by Robert Sabel, the Roughchild group works solely on BMWs—and has been doing so for over a decade. They will assemble an airhead with their eyes closed, and so they know precisely what mods are ‘should dos.’

Some time in the past they took a traditional BMW R75/5, bored it out, slimmed it down and modernized the operating gear. They known as it the RSWB, for Reisesport Quick Wheel Base, and instantly locked in orders for 9 extra builds utilizing the identical method.

That is the primary one to roll off the bench, and it’s a stunner.

The donor for this challenge was a 1973 R75/5—but it surely wasn’t precisely operating when it arrived. “The donor got here in as a dilapidated basket case out of the Pacific Northwest,” Robert tells us, “but it surely got here with a title. The story goes that the vendor’s father had stashed two bikes within the basement as restoration initiatives, and didn’t get to them in time.”

“Every thing wanted to be rebuilt, and any authentic elements that weren’t salvageable have been changed with elements from stock.”

As soon as the BMW was torn down, Roughchild began by repairing, bracing and de-tabbing the body. Then they added a subframe of their very own design, with a mix LED taillight and switch alerts built-in within the rear, and a license plate decrease down. The setup’s capped off with a low profile seat, simply lengthy sufficient to take two in a pinch.

Subsequent, Roughchild upgraded the suspension with a set of Showa upside-down forks, held in place by {custom} yokes. Out again is a pair of Öhlins piggyback shocks.

The wheels are 18” Excel rims laced to a {custom} CNC-machined hub (entrance) and an OEM BMW hub (rear), with stainless-steel spokes and Bridgestone Spitfire tires. The crew up to date the entrance brakes with a pair of Brembo calipers, with the grasp cylinder tucked away underneath the gasoline tank.

Naturally, the motor’s had a major bump too. It’s been rebuilt to 1,000 cc, with refurbished heads, bigger consumption and exhaust valves, a Silent Hektik alternator and a high-output ignition. The revised electronics are powered by a Shorai Lithium-ion battery, housed in a {custom} battery tray underneath the tank.

Roughchild additionally put in Mikuni VM34 carbs, re-jetted them, and drilled the airbox to resemble the one on the 1977 R100RS. The exhaust system is a full stainless-steel affair, with {custom} headers and ‘Quiet-Core’ mufflers from Cone Engineering. Roughchild say the outdated airhead’s now good for 60 hp and 70 Nm—a noticeable improve from the unique.

Transferring to the bodywork, the store saved the unique headlight and toaster tank, however swapped the entrance fender for a shorter unit. The headlight internals have been upgraded to LEDs, and the unique speedo was changed by a BMW MotoMeter unit that features a tach and indicator lights.

Simply behind it are Renthal bars, fitted with Magura grips, bar-end flip alerts and new switchgear. Upgrades which are tougher to identify embrace custom-made washers on key mounting factors, and zinc plating on all the unique {hardware}.

“The result’s a traditional cafe racer with fashionable dealing with traits, wonderful brakes and ample energy,” says Robert. And it’s one heck of a looker too, resplendent in BMW’s Granada Purple coloration, with hand-painted pin stripes.

Roughchild has eight extra RSWB builds within the queue… however they’re off to begin.
