![]() ![]() 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. Vehicle Hold Control (VHC) applies and holds brake pressure when activated and prevents the motorcycle from rolling after the rider has released the brake controls. 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).Ĭhopblocks for Charity: Bond’s Scrambler 1200 XE Rakes in Four Times the Projected Price When DSCS detects excessive rear wheel slip under deceleration it will adjust engine torque delivery to better match rear-wheel speed to road speed. Drag-Torque Slip Control System (DSCS) and Cornering Enhanced Drag-Torque Slip Control System (C-DSCS)ĭrag-Torque Slip Control (DSCS) is designed to reduce excessive rear-wheel slip under deceleration, which typically occurs when the rider makes an abrupt downshift gear change or decelerates on wet or slippery road surfaces.The action of C-TCS is also tailored when cornering based on lean angle. The rider may select one of two traction control modes: Standard Mode is optimised for dry surfaces Rain Mode is optimised for wet surfaces. 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 Cornering Enhanced Traction Control System (C-TCS) is designed to prevent the rear wheel from excessive spinning under acceleration when going straight or cornering. Cornering Enhanced Traction Control System (C-TCS).The brake pressure required to limit wheel slip when cornering is typically lower than the pressure required under straight line operation. Cornering Enhanced Antilock Braking System (CABS) 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. ABS operates independently on front and rear brakes to keep the wheels rolling and prevent uncontrolled wheel lock. Cornering Enhanced Antilock Braking System (C-ABS)ĪBS is designed to prevent the wheels from locking under braking and helps the rider maintain control when braking in a straight-line, urgent situation.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. Cornering Enhanced Electronic Linked Braking (C-ELB) takes into account the motorcycle lean angle or Trike lateral acceleration. Applying the rear brake pedal alone will cause the system to also apply an amount of braking to the left front calliper. When linked, applying the front brake lever alone will cause the system to also dynamically apply an amount of braking to the rear. The system provides more linking when the rider is applying heavier braking and reduces or eliminates linking for light braking and low speeds. 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. 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. Cornering Enhanced Electronic Linked Braking (C-ELB).The rider is ultimately responsible for steering and path corrections.įeatures of RDRS include (from the press release): This is a key difference between motorcycle RDRS and Automotive Stability Control. RDRS is not a system to directly influence vehicle direction. coasting through a corner with the clutch disengaged). 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. 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 tyre from exceeding available grip. Interestingly, Harley has included this disclaimer for those dumb enough to believe RDRS increases traction or improve rider abilities:Īvailable traction is determined by the road/tyre interface. Not only does RDRS feature traction control, but also cornering ABS, linked braking, clutch assist to limit rear wheel lock-up, tyre pressure monitors and even assistance to prevent you rolling backward on hill starts! ![]() It’s also included in the electric LiveWire which will not be available in Australia until late next year. They call it Reflex Defensive Rider Systems (RDRS) with chassis control, electronic brake control and powertrain technology.
