YWTFRB! CHAPTER EIGHT TECHNICAL INSPECTION GENERAL MACHINE REQUIREMENTS Every racebike must be ready to race when it is brought to technical inspection. All machines participating in WERA events, or events hosted by WERA affiliates, must prominently display the WERA decal (meaning the entire 4” circle) on both sides of their machine. Points and awards may be withheld from any racer who fails to display the WERA decals.
