[attachment=59]Hi I have just joined this sight as a member. I put together this BMW rig in April. I built a full subframe as the R75/6 has a very light rear frame.June 11, 2014 at 6:04 am #5812
Not sure what happened to your pic there Coriman.
I’m looking at getting a subframe made for my R80, it’s an ’86 and apparently they aren’t as strong as the earlier frames. Are you able to post up some pics of your subframe?June 11, 2014 at 10:46 am #5813CorimanParticipantRank: 125cc Rider
I can do that, when I work out what went wrong with my post and picture thing I will try again.
The R69 had a purpose built frame for sidecars with fully welded large diameter heavy tube to the rear frame. Subsequent models had a bolt on rear section with small diameter tube to the rear shocks, so you can,t bolt onto the rear frame without strengthening it. I designed and built my own subframe kit for twin shock models, but I assume your bike has a single shock, which would probably change some of what I have done.
:huh:I will start again with this photo of my outfit

Yeah mines a singleshock, but I’m just as interested in what you did at the front and how and where you ran the subframe from front to back.June 20, 2014 at 10:39 am #5830
I showed your pic to my mate Pete, who lives with Hugh Anderson Junior. Junior remembers the bike as he did many many miles on the back of it behind Hugh senior.
