I had been thinking about an old boxer with modern suspension and brakes above and beyond using parts from our friends at Cognito Moto(which we did). I figured if I started thinking about it the right bike would come along.
I received a phone call from the president of the local BMW club asking if I was interested in a wrecked 1975 R90S? Yes I was. He put me in contact with the owner of the bike. Bill had been restoring this bike he has had for 30 years for the past 20. This was his end all BMW and the last bike he would ever ride or own.
Only a few months after he completed the bike a car turned in front of him and the rest is history. We drove down to pick the bike up and Bill had a pile of spares, books and tools. He had been a BMW tech and had his own shop in the 1980’s. We brought enough parts with us to make the bike a roller and back to the shop we went.
Over the next few months I started taking inventory of what was salvageable on the bike, what parts we had in the shop and what I needed to source.
Like all of our builds it has to be different, cool, fast and rideable(most important) I had seen a few bikes in Europe where they converted a twin shock to a Paralever rear suspension like you would see on a BMW R1100GS. That was the beginning. Spoke wheels are a must. There is nothing worse than building a vintage bike with cast wheels.
No sooner than I had collected enough bits to start the build I get a phone call from a new customer asking if we could build him an Urban Scrambler. I said - We have the bike for you.
This is the second time I have started a personal project and it went to some else before I finished it.
Dan(the customer) lives in a part of the country that gets only a couple months a year of riding weather not that stops him from getting on his modern BMW and riding South in the Winter.
Dan’s had only a few requirements. The seat had to fit his 5 year old son so they could rie around there small town and it had to make him feel like there was no reason to ride his modern BMW bike.
We first showed this bike at the Bay Classic in San Francisco and then at the 1 Moto Show in Portland, Oregon. We have been so busy it has taken a while to get around toi an article and for Rebecca to do a proper photo shoot.
The base bike is a 1975 BMW R90S
Modern Japanese forks
Spoke wheels with Sun rims
BMW paralever rear suspension from a R1100GS
Custom shock from TFX
The motor, transmission & rear drive only had a few thousand miles on them so we did not have to do much there. The gas tank is from a late 70’s BMW /7 series, the seat & rear frame is custom made at Boxer Metal, Some of the visible parts are from Motone & Motogadget.
We pulled it off. The custom loved the bike so much we are redoing his 1976 R75/6 and he won't get back on his newer BMW.
Here are a few things we used on this build.
