My friend and I just picked up a 1974 BMW R60/6 yesterday in perfect condition (pics to follow).
I am used to modern sportsbike. My own personal ride is a Z750S.
So this whole vintage/class thing is very new to me and I am probably going to come back often for help and advice.
As it happened, my friend already laid it down yesterday in a turn.
He is a new rider.
When I picked it up and rode it into a parking lot, I noticed the brakes. The braking power is very poor. Is that normal? Or am I just not used to the type of brakes?
Also, he broke the glass of the headlight and I have no idea how difficult it is to find a new one. Are those parts bike specific or may I be able to also search for other models? Are those glass covers interchangeable between certain BMWs?
Use this site - http://www.realoem.com/bmw/select.do - for an on-line fiche for parts for the bike. You'll have to select "motorcycle" and "archive" to get to the /6. Enter the VIN and begin browsing for parts.
It appears that the part number is 63121358147. Using in the parts application search feature, it appears to be used on many other BMWs, even some of the later oilheads and cruisers. Just about any /6 up to 1981 (not the RT models with the enclosed fairing), the R100R, the R850R, the Mystic...quite a few models.
The R60/6 has drum brakes. Properly set up drum brakes can be quite effective. In the same time frame, BMW came out with the single disk brake. While it can also be reasonably good (not as good as today's bikes, for sure), some have decided to switch back to a drum for better braking. Be sure the cable and pads are adjusted correctly.
You may need to get an aftermarket repair manual such as Haynes or Clymers. They're are some errors in these books, so always double check other sources for info, especially tightening torques on critical components. A good source for all things Airhead is Snowbum's website. He's put a great deal of stuff out there, so don't get overwhelmed..take it a little at a time!
Another good source for Airhead info is Anton Largiader site:
