Key Safety Reminders
Never tow this vehicle with wheels on the ground — always use a trailer or transport vehicle.
Do not operate with a discharged or missing 12V battery — electrical components and safety devices can be damaged.
If coolant temp warning appears — stop immediately, do not endanger others. Let engine cool before checking coolant.
ABS warning lamp on while riding = ABS not active. Wheels may lock. Stop safely and contact KTM workshop.
Kill switch is for emergencies only. Always use ignition key to switch off engine — leaving ignition on discharges battery.
