The top of the lines on my twin Brembo 1983 R65 are starting to abrade after 30 years of movement. So, I happen to like the black stainless braided pipes and winter is coming.... I have a couple of questions about parts which the 'custom' brake line makers seem to want to run away from:

I have a BMW dealer fitted RT fairing (fitted in UK) without storage boxes and vents etc which suits the bike nicely.
RT higher bars (checked the measurements).
Standard R65 brake routing and they go through the moving black plastic shroud under the headlight rather than out the sides like the 80s and 100s that came with factory fairings.

The top line must be slightly longer that standard due to the bars.
I'd like to delete the hard lines on the callipers and the smaller stainless fittings seem to allow that with the bleed nipple next to them.

After several abortive attempts with suppliers who see "early 80's BMW non-standard" and shut the hatches down with orange beacons and sounders going off. I understand thread sizes, I can measure pipes and can look up parts online. I'm just after a bit of guidance before re-inventing the wheel  :mad:

For years I used to have all my brake lines made up by hose workshops as "hydraulic lines" to allow them to avoid the liability concerns associated with making up brake parts.

If I were you I would obtain the standard parts (or have modern analogues made up) to that your "hydraulic" lines run initially from the handlebar master cylinder to the standard RS/RT distributor that straddles the frame top tube. From there to the front of the fairing lower by way of solid pipe. At the fairing - "standard" braided hose lines to each of the callipers, I would retain the hard lines at the callipers as using the standard components minimizes the amount of custom work required/

Won't Spiegler (sp?) make custom length brake lines?  When I was in the Army I had the hydraulic shop (I worked in aviation) make lines for my bikes.  AN fittings and steel-braided teflon core line.  Made super brake lines!

All of the SS lines I've gotten for my Beemers came from Moto-Bins...

To which I should have added that more recently I have bought all my brake lines from Motobins, in fact I was lucky enough to score the complete K100 set when they had them on a really good special.

Regular price on M-B's SS lines was cheaper than rubber lines from the local dealer...
