Hour meter Athena S410000395003 — wireless

Wireless hour meter. It starts counting from the vibrations of the running engine, so there is no wiring and no lead to the spark plug. Recorded hours are the basis for service planning: oil and filter changes, piston and valve checks. On a motocross bike it measures wear better than mileage, which the machine does not record. Mounts on any flat surface such as a fender or bracket.
