If you change preload setting to adjust the static and rider SAG on your BMW S1000RR, you need to re-calibrate the zero point for height of the bike above the rear wheel. These bikes measure how high the rear is so that it can anticipate rear wheel lift and apply ABS (except when in Slick Mode) as the rear wheel loses traction. Incorrect zero point can result in incorrect application of ABS when you don't want it applied.
