RDRS features are standard on all 2020 Harley-Davidson CVO, Tri-Glide Ultra and Freewheeler® models, and the 2020 Harley- Davidson LiveWire model. RDRS features are optional on all MY20 Touring models in the U.S. (except Electra Glide ® Standard models). ** Available traction is determined by the road/tire interface. The systems bundled into the RDRS are only able to adjust brake pressure or powertrain torque in an attempt to keep the forces at the tire from exceeding available grip. These technologies do not have the ability to increase grip, or to intervene when the rider has not made a brake or throttle application (e.g. coasting through a corner with the clutch disengaged). RDRS is not a system to directly influence vehicle direction. This is a key difference between motorcycle RDRS and Automotive Stability Control. The rider is ultimately responsible for speed, steering, and path corrections. Features of RDRS include: • Cornering Enhanced Electronic Linked Braking (C-ELB) This feature applies braking effort to both wheels when the rider uses either the hand lever (front) or foot pedal (rear) brake control, which can help many riders achieve better braking performance. The Electronically Linked Braking (ELB) system provides more responsiveness and allows for more balanced front and rear braking under a wide variety of brake applications. The system provides more linking when the rider is applying heavier braking and reduces or eliminates linking for light braking and low speeds. When linked, applying the front brake lever alone will cause the system to also dynamically apply an amount of braking to the rear. Applying the rear brake pedal alone will cause the system to also apply an amount of braking to the left front caliper. C-ELB takes into account the motorcycle lean angle or Trike lateral acceleration. C-ELB will alter the proportioning of brake pressure between the front and rear brakes when braking while cornering in an attempt to improve the ability of the bike to maintain the rider's intended path. The C-ELB feature is standard on all 2020 CVO and Police models and optional on all 2020 Touring models in the U.S. (except Electra Glide Standard models). • Cornering Enhanced Antilock Braking System (C-ABS) Anti-Lock Braking System is designed to prevent the wheels from locking under braking and helps the rider maintain control when braking in a straight-line, urgent situation. ABS operates independently on front and rear brakes to keep the wheels rolling and prevent uncontrolled wheel lock. C-ABS is a variant of ABS that takes into consideration the lean angle of a two-wheel motorcycle, or the lateral acceleration of a Trike model. The brake pressure required to limit wheel slip when cornering is typically lower than the pressure required under straight-line operation. The C-ABS feature is standard on 2020 LiveWire, CVO, Trike, and Police models and optional on all 2020 Touring models in the U.S. (except Electra Glide Standard models). ABS is a feature on all other H-D models (or where selected in lieu of C-ABS). • Cornering Enhanced Traction Control System (C-TCS) C-TCS is designed to prevent the rear wheel from excessive spinning under acceleration when going straight or cornering. C-TCS can improve rider confidence when available traction is compromised by wet weather, a sudden unanticipated change in the surface, or when riding on an unpaved road. The rider may select one of two traction control modes: Standard Mode is optimized for dry surfaces; Rain Mode is optimized for wet surfaces. The system can also be turned off. The action of C-TCS is also tailored when cornering based on lean angle. This C-TCS feature is standard on all 2020 LiveWire, CVO and Police models and optional on all 2020 Touring models in the U.S. (except Electra Glide Standard models). • Drag-Torque Slip Control System (DSCS) and Cornering Enhanced Drag-Torque Slip Control System (C-DSCS) DSCS is designed to reduce excessive rear-wheel slip under deceleration, which typically occurs when the rider makes an abrupt down-shift gear change or decelerates on wet or slippery road surfaces. When DSCS detects excessive rear wheel slip under deceleration it will adjust engine torque delivery to better match rear-wheel speed to road speed. On models equipped with C-DSCS the action of DSCS may be tailored when cornering, based on detected lean angle (two-wheel motorcycles) or lateral acceleration (Trike models). DSCS is standard on all 2020 CVO and Police models and optional on all 2020 Touring models in the U.S. (except Electra Glide Standard models). C-DSCS is standard on all 2020 LiveWire and Trike models • Vehicle Hold Control (VHC) VHC applies and holds brake pressure when activated and prevents the motorcycle from rolling after the rider has released the brake controls. The primary function of VHC is to prevent the motorcycle from rolling when it is stopped – for example at a stop sign on a hill, in stop-and-go traffic on a slope, or on a steep decline out of a parking structure. VHC is designed to make it easier to ride away with confidence by minimizing the number of controls needed to pull away smoothly. The
