Motorcycle News - Stunning Sigrid: A most unusual BMW R90/6 from Titan
https://ift.tt/2OnUp54
This new build from Austria’s Titan Motorcycles is very different, though—and unlike many builds that try to be different, it works beautifully. You’d never guess, but it’s based on an R90/6 from the 1970s, which means it has the 898 cc version of the venerable air-cooled motor.
Michael was primarily looking for an engine, because two-valve airhead motors are becoming rare in Europe. So he met up with the retired gentleman selling the BMW, in a carpentry workshop in the middle of nowhere.
Back in Graz, Austria’s second largest city after Vienna, Michael debated whether to resell some of the parts on eBay, to earn back a few Euros—or to invest many more hundreds to make the R90/6 a functioning motorcycle again.
An R75/5 gearbox was grafted onto the engine, and an R45 swingarm to accentuate the vintage vibe. Michael didn’t want to take any chances with the shaft drive though, so he’s installed a newer R80/7 kardan setup.
A concept started to form in Michael’s mind. “I had a 1920s tank concept, like a museum piece, or a racing bike from pre-war times,” he recalls. “But that style was not really feasible, due to the high frame beam of the BMW.”
The seat support is welded directly onto the tank, with the original subframe brackets bearing the weight of the rider. It’s a neat arrangement, not least because Michael didn’t want to cut into the valuable R90/6 frame (which, incidentally, is homologated for sidecar use as well).
Michael calls it ‘the real Austrian coffeehouse racer look,’ with milled grooves and an original Wiener Geflecht Viennese mesh insert. We’re told it’s very comfortable too.
‘Stunning Sigrid’ was finished just in time for June’s famous Club of Newchurch Festival, which attracts 15,000 bikers every year to the beautiful Austrian Alps.
And yes, it’s sacrilegious to sit a BSA tank on a BMW frame. But it’s also a much-needed touch of humor in the homogenous world of airhead customs.
