THis set is my latest effort. On BMW’s from 1981 to 1986, the teles have a bulge at the bottom which can foul the disc bolts and event the disc itself. That means only two locations for the axle are available to move it forward to reduce the trail effectively. I tried the 52mm forward position, but that still made it heavy to steer but better. I then decided to go to 83 mm. 9to the front side of the bulge) That has been a success but it also needed bracing to prevent fork flexing on hard reght hand corners. This bracing has fixed that problem. Now it’s like having power steering.
