Precision Engine Monitoring for Superior Preventative Maintenance
Take control of your vehicle’s maintenance schedule with the Hardline Products® Inductive Hour/Tach Meter. Engineered for versatility and durability, this essential diagnostic tool works on any gasoline engine up to 8 cylinders, making it perfect for motorcycles, ATVs, UTVs, PWCs, marine outboards, and generators.
Whether you are managing high-performance 4-stroke motocross bikes with strict service intervals or tracking hours on a marine engine, this meter provides the data you need to extend engine life and maintain peak performance.
“A hour meter, plain and simple. Four-strokes live and die by how much time you put on them.” — Mitch Payton, Pro-Circuit® (as interviewed in Motocross Action Magazine)
