OK guys I have a question(and it has probably been done to death but take pity, my Google-Fu is weak).

I have a 1989 K100 RS SE with ABS. The brake lines are as BMW intended but like the rest of the bike they are 1989 vintage and don't feel as "clean" as I think they should. I have been looking at the Gooderidge web site & talking to the peeps at K300 and I can't find a set that matches. As far as I can see both the front & back set are 2 line. And I can't find a set-up like that for an ABS bike. Anyone else had the same problem & sorted it out ? Is the 4 line front set 2 x flexible and 2 x rigid ?

There are 2 steel lines that go from steering head area to the Front ABS Modulator on the left side and 1 flexible to one of those lines to the master cylinder and 1 flexible from the other steel line to the right caliper.
I just purchased a set for my K1100LT from Motobins for very reasonable prices. From memory something like 78 squids for the set.
