Feedback from the IMU enables an additional function: corner braking management. In addition to front and rear wheel speed sensors (standard for any ABS system), the enhanced ABS uses information from the IMU to calculate the motorcycle’s lean angle. Should riders use the brakes beyond the entrance to a turn (i.e. trail braking), increase brake force mid-corner (e.g. to avoid an obstacle), or encounter a sudden change in surface traction (e.g. fallen leaves, loose sand or a wet patch), brake force is modulated to suppress erratic vehicle behaviour and slippage. This assists riders in holding their intended line through the corner instead of running wide, or in coming to a controlled stop.
