TUNING THE ENGINE 18 18.1 Ride Mode Possible states Street – Homologated performance with balanced response; • the motorcycle traction control allows normal slip on the rear wheel. Rain – Reduced homologated performance for better ridabil- • ity; the motorcycle traction control allows less slip on the rear wheel.
18 TUNING THE ENGINE 18.3 Slip adjustment (optional) The slip adjustment is a motorcycle traction control function. The slip adjustment allows the motorcycle traction control to be tuned through nine levels to the desired characteristic map. Level 1 allows the maximum slip on the rear wheel, and level 9 the minimum.
