This is the brake line that is included with our R1200 R Touring handlebar set, sold separately. If you are ordering the kit, you do not need this line because it is included in the kit. We offer this line for custom applications separately.
This brake line is also sometimes needed when installing our Vario Risers, when set in the rear most position. Due to model specific tolerances, the brake line is not always needed with our Vario Risers. You can order one and return it if not needed or you can use the forward or middle position and retrofit the brake line later if needed.
