    ANTI-LOCK BRAKE SYSTEM (ABS)Included: ABS is designed to prevent the wheels from locking under braking and helps the rider maintain control when braking in a straight-line, urgent situation. TRACTION CONTROL SYSTEM (TCS)Included: The TCS is designed to keep the rear wheel from “spinning out” when the motorcycle is accelerating in a straight line and enhances rider confidence.
    DRAG-TORQUE SLIP CONTROL SYSTEM (DSCS)Included: DSCS is designed to reduce excessive rear-wheel slip and help prevent rear-wheel lock under powertrain-induced deceleration, which typically occurs when the rider makes an abrupt downshift gear change or quickly reduces the throttle while on wet or slippery road surfaces. TIRE PRESSURE MONITORING SYSTEM (TPMS)Included: TPMS alerts the rider through the information display to low or high tire air pressure. Maintaining proper tire air pressure is important both for vehicle performance and tire life.
    CORNERING ENHANCED ANTI-LOCK BRAKE SYSTEM (C-ABS)Included: 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 or lower than the pressure required under straight line operation.
