Info
SpeedBox2 for Yamaha 2019 is a revolutionary process-control module which suppresses the speed limiter of your electric bike. After installation and activation of your SpeedBox for Yamaha the display will show actual values. Values such as distance travelled and range are correctly displayed.
If you have a new bike which hasn't been ridden at all, you must ride it at least 1 or 2 kilometers before you install the SpeedBox tuning kit.
