Race to Rebuild the BMW R90/6

The Motorcycle Classics/Dairyland Cycle Insurance 1974 BMW R90/6 Race to Rebuild project finally wraps up — and it’s lovely.

| May/June 2013

It’s been a long haul “building” the Motorcycle Classics/Dairyland Cycle Insurance Race to Rebuild BMW, and now that it’s finally finished, we’re kind of sad it’s done.  

Why the quote marks around “building?” The truth is, we didn’t actually “build” anything. What we did, however, was take a tired old BMW and give it a healthy injection of fresh parts for a new lease on life. In the process, we also gave it a new attitude, applying the requisite pieces to turn a staid tourer into a café-themed road bike.

Those pieces include the big things that jump out at you like the custom wheels, the replica Ducati 900SS fairing, the R90S low bars, the R100RT gas tank, the bum-stop solo seat, rearsets and the Dunstall-style mufflers. But there are a lot of details that go into a build like this.

It’s the little things …

Those details include items like the minimalist brushed aluminum turn signals and cats eye taillight we sourced from Dime City Cycles, and the very nice San Jose-style fork brace from Brad Phillips at Phast by Phillips.

Other touches include the fiberglass starter cover from Boxer Works, which we had TC Concepts paint to match the bodywork. The fiberglass cover deletes the factory two-piece aluminum cover that also houses the stock air filter — not a problem as we swapped the stock Bing carburetors for a pair of 32mm Mikunis from Rocky Point Cycle, shod with K&N pod filters. That left the issue of the engine breather hose under the cover that normally dumps into the right intake pipe, now gone. We worked around that by fabricating a simple dump can with a rubber elbow sourced from an old Kymco (!) scooter that the stock breather hose plugged into perfectly. A filtered outlet from the dump can allows normal breathing without an oily mess.

We also had Stuart at Custom Coatings powder coat the front engine cover gloss black to match the valve covers and frame. For a final touch we sanded the raised ribs on the cover to bare aluminum to match the valve covers. Nice.

stormguzzi. Sorry I didn't see your post earlier. I should have some fairly detailed shots of the bracket I made for the fairing. It takes some fabricating, but it's certainly doable. I'm hardly an experienced fabricator, I can tell you that. Post again and we'll figure out how to get you some pics. Richard/Motorcycle Classics
