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.
