The Cornering Enhanced Antilock Braking System (C-ABS) is a variant of ABS that takes into consideration the lean angle of the motorcycle. While cornering, the available grip for braking is reduced and C-ABS automatically compensates for this reality.

Models equipped with C-ABS have a traction control button and a traction control icon that lights when power is turned on, see Operation → Left Hand Control Switches and Operation → Instruments.

The C-ELB system provides 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. C-ELB takes into account the motorcycle lean angle and will alter the proportioning of brake pressure between the front and rear brakes while cornering in an attempt to improve the ability of the bike to maintain the rider’s intended path.

Vehicle Hold Control (VHC) uses brake pressure to keep the motorcycle from rolling downhill when it is stopped on an incline, making it easier to ride away when starting on an incline, such as a hill, a bridge or a parking ramp. The VHC holds brake pressure when activated and prevents the motorcycle from moving after the rider has released the brake controls. The system holds brake pressure until the rider actuates the throttle and clutch to pull away.

Activation: The rider activates VHC by 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 squeeze. A 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.

Deactivation:VHC is deactivated automatically as the rider begins to pull away from a stop, or if the rider firmly applies and releases either brake control. VHC may deactivate if rider aggressively revs the engine with clutch lever pulled in. VHC will also deactivate if the rider lowers the side stand on models with a side stand sensor (not in all markets) or shifts into neutral on models without a side stand sensor. VHC will deactivate when engine stops running. VHC will deactivate after between approximately 3 minutes and 5 minutes. In most situations, the indicator light will flash and the VHC will release if there is no rider action. (VHC may deactivate in less than five minutes to prevent overheating if being used often on steep grades.)

TPMS alerts the rider to low tire air pressure. Maintaining proper tire air pressure is important both for safety and for tire life. The TPMS displays current front and rear tire pressure on the Instrument Module (IM) and displays an indicator to alert the rider when tire pressure is low, and the pressure should be checked.

Motorcycles equipped with C-ABS must always use Harley-Davidson tires and wheels. The C-ABS monitors the rotational speed of the wheels through individual wheel speed sensors. Changing to different diameter wheels or different size tires can alter the rotational speed. Different-sized wheels and tires can upset the calibration of the C-ABS and have an adverse effect on its ability to detect and prevent uncontrolled wheel lockups. Operating at tire pressures other than those pressures specified can reduce C-ABS braking performance. Refer to .
