The F1 mirror takes its name from the Formula 1 series. The mirror has the same shape as the rear view mirror of Silver Arrows or Ferraris. It is probably one of the best-selling styling mirrors of all. The mirror is universal for left or right side of the vehicle. It has an M8 thread and comes with a left hand thread adapter. This is required in vehicles which have a mirror on the right handlebar on a left hand thread.
