With the 12, 8V 2 Ah Lithium-Ion batter located under the seat and close to the centre of gravity, the handling of the TC 250 is uncompromised. The engine is easily started and stopped via the same handlebar-mounted switch for improved ease of use.
- Map switch
- Adding Electronic Fuel Injection (EFI) to the TC 250 allows for the introduction of two engine maps that cater for riders of all abilities. Map 1 is the standard option, that delivers linear, predictable power, while map 2 is aggressive with improved throttle response and a sharper, explosive power output. By simply pressing a button on the handlebar-mounted map switch, riders can toggle between the two options and select their chosen map.
- EMS
- The new Engine Management System (EMS) is designed to be smaller and lighter while also faster at processing data. It incorporates a new rollover sensor (ROS) which cuts the ignition and shuts off the engine for safety in the event of a severe crash, adding another level of safety to Husqvarna Motorcycles' new generation motocross line-up.
- Hour meter
- A new hour meter comes with an integrated fuel level indicator which is visible on the FI status LED, indicating to the rider when the fuel level is becoming low.
- Start/stop switch
- The new combined start/stop switch is located on the right side of the handlebar for easy, thumb-operated use. Not only simplify the starting and stopping of the engine, the removal of a designated stop only button from the handlebar reduces the risk of potential damage or activation in the event of a fall.
