Based on one of the last ever build BMW R100 R of 1995, I´ve found the donor bikein the area of Stuffgart with only 39.000 kmon the clock in perfect state.
I was never keen on a R80 or R100 RT due to its technical challenges and less advanced drive/cardan for example.Ironically what I was keen for was the “old” style of the most sexy air cooled engine ever build and the look and design of the70ies BMW Boxer engines. That said I spent lots of time building my R100 R engine back to exactly that design.The frame, seat pan and tank anglehowever had to complement the focus on THAT engine and give it “room to breathe”.Also it was clear I didn´t want to exagerate too much on other parts like a custom USD
fork or a completely different exhaust system. These parts are still original though completely overhauled. (Like almost everything and every single screw) To differentiate from the thousands of other Custom BMW Boxer we´ve already seen I turned my focus to the non-obvious details.
From handmade aluminum BMW M3 designed valve caps with 90-degree valves to a custom upper fork bridge, keyless go, to even a brass wing nut at the rear brake.Talking about technology. Most custom builders waive for important speedometer indictors for the sake of less cables running along the frame. (Oil pressure or neutral eg) To me it was clear I want the “full house” on my Motoscope Tiny and…there are no cables running along the frame…or even in
the frame! (Hello German TÜV) Another design challenge comes with the original R100 R massive gas tank. I for sure wanted to keep it and not swap. (We´ve seen this already….)And I think the job on the tank is not that ugly. At least I don´t have to stop every 100km at a gas station.
