Safety Wiring Techniques

Safety wiring is not mysterious or difficult. It really only takes some time and practice, and will soon become second-nature for you at the track. Safety wiring should always be done to keep bolts or nuts from backing out. That means always wire in the direction that will tighten the bolt. Safety wiring is also done to prevent any part that does come loose from falling onto the track and causing damage to another bike or rider. It never hurts to safety wire any critical part of your bike, such as controls, beyond the requirements in the rulebook.
