According to my VIN, I have a Jan 1985, US bike. Based on the two parts diagrams for single brembo brakes for pre 85 and 85 and on, it looks like I have a hybrid of sorts. Pre 85 bikes are supposed to have a banjo fitting at the master cylinder and 10 mm female fitting at the caliper end (attached to the fixed tubing). 85 and on are supposed to have a two line setup, with a coupler between and a pressure switch for the brake light.
In any case , I now have a Vennhiil SS brake line with 10mm male and 10 mm female adapters. I'm really pleased with the improvement and the service from Vennhill was great.
