I removed my wheels to have new tyres fitted then, when I refit the wheels I had to pump the front brake lever to get the discs engaged then, when I set off for a spin to scrub the tyres off an ABS failure warning flashed up on the screen. It said it was OK to ride but I should take it to a workshop. Not long after that it said traction control has also failed. Does anyone know if this can be fixed at home or will I need to take it the dealer. The bike is a 2018 GSA WITH less than 8k on the clock.
