Rider Safety Enhancements

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.

Cornering Enhanced Traction Control System (C-TCS)

Included: C-TCS is designed to prevent the rear wheel from excessive spinning under acceleration when going straight or cornering.

Cornering Drag-Torque Slip Control System (C-DSCS)

Included: On bikes equipped with C-DSCS, the system helps keep the rear wheel from slipping or locking up when you quickly downshift or let off the throttle, especially on wet or slippery roads. When turning, it can adjust based on how much a two-wheel bike is leaning or the side-to-side motion on a Trike.

2. Range estimates are made in accordance with WMTC 134/2014 Annex VII Appendix 3.3 and are based on the expected performance of a fully charged battery under specific operating conditions. Actual range will depend on driving habits, weather conditions and equipment. The range shown is at maximum power setting and minimum regeneration.

3. Recommended 91 octane (95 RON) or higher fuel (R+M)/2.

4. Values shown are nominal. Performance may vary by country and region.

7. Price quoted is recommended retail price in € ex works including 19% VAT plus transport and set-up fee: €560 for Sport, Cruiser, Grand American Touring, Adventure Touring and LiveWire, €1260 for Trike. The total price includes 4 years warranty: 2 years manufacturer’s warranty and 2 years extended warranty. (The warranty is provided by the authorised dealer named and signed in the warranty agreement and insured by CG Car-Garantie Versicherungs-AG. It is subject to the applicable warranty conditions).
