Reflex™ Defensive Rider Systems (RDRS)

C-ABS is a variant of ABS that tailors brake pressure to longitudinal slip based on motorcycle lean angle or trike lateral acceleration. The system is intended to preserve lateral grip at the tire contact patch while under combined cornering and braking loads.

The Cornering Enhanced Traction Control System (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.

C-TCS is standard on all MY20 LiveWire™, CVO™, Police and Trike models and optional on all MY20 Touring models in the U.S. (except FLH

When DSCS detects excessive rear wheel slip under deceleration it will adjust engine torque delivery to better match rear-wheel speed to road speed.

Cornering Enhanced Drag-Torque Slip Control (C-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 C-DSCS detects excessive rear wheel slip under deceleration it will adjust engine torque delivery to better match rear-wheel speed to road speed. The action of C-DSCS is also enhanced when cornering based on lean angle.

The Vehicle Hold Control (VHC) applies and holds brake pressure when activated by the rider 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 coordinated controls needed to pull away smoothly. The system applies brake pressure until the rider actuates the throttle and clutch to pull away. VHC may also be engaged when the motorcycle is stopped on a flat surface if the rider wants to maintain position without applying pressure to a brake control.

The rider activates VHC by momentarily applying extra pressure to either the front-brake hand lever or the rear-brake foot control after the motorcycle has come to a complete stop. If rider brakes very hard to a stop, and holds the brake pressure after stopped, VHC may also set without any added pressure. The VHC indicator light will illuminate to confirm that the rider has activated VHC, and the ABS system will hold brake pressure after the rider releases the brake control. VHC is disengaged automatically as the rider begins to pull away from a stop, or if the rider applies and releases either brake control.

VHC is not to be used as a parking brake. It will also disengage if the rider lowers the side stand (on models with a side-stand sensor, not a feature in all markets) or shifts into neutral on models without a side-stand sensor, or if the engine is turned off. In most situations after five minutes the indicator light will flash and the VHC will release if there is no rider action.

VHC is not intended as a substitute for a parking brake in any situation.

This feature is standard on all two-wheeled MY20 CVO™ and Police models and optional on all two-wheeled MY20 Touring models in the U.S. (except FLHT).

The TPMS displays current front and rear tire pressure on the Boom!™ Box GTS screen (or on the odometer on Road King® models) and displays an indicator to alert the rider when tire pressure is low, and the pressure should be checked.

TPMS is a feature of RDRS and is also available as a stand-alone accessory through P&A for MY20 Touring models (except Japan) equipped with Original Equipment or Accessory wheels that accept a TPMS sensor.
