I recently installed the 1.75" Rox risers designed to use the existing brake and clutch lines on the F800GS. While they did work as advertised, the front brake cable was still stretched pretty tight when at full lock. Looking at it after comments from a friend, I realized that the lower banjo fitting for the brake line sticks straight out and makes almost a 90 degree bend. To relieve the stretched line, I simply took my channel lock pliers and carefully bent the metal part of the cable upwards a bit. That little bit made a big difference. Now the bike can be turned from lock to lock without over stretching the brake line. Here is a pic....sorry for the quality.
