Apico Lanyard Kill Switch that connects to your existing circuit on modern Trials bikes. The Lanyard Kill Switch works by being attached to both rider and bike. The cord which is attached to the rider pulls away from the switch in the event of a dismount and in turn switches the engine off. It is now a enforced rule by the ACU that all Junior riders must have a safety power cut out device fitted and entry to events will not be allowed without one. Spare Lanyard Leads available separately.
