Chromoly steel, with its high strength and exceptional toughness. We also use well-balanced tempered steel depending on the power output characteristics and operating environment of each vehicle model, ensuring high reliability with the optimal material for each application.

Carbonitriding and quenching enhances surface hardness. We significantly reduce wear at the chain engagement area, achieving both a long life and high durability. This quality stands up to heavy use.

Optimized tooth tip shape reduces drive resistance. Smooth chain engagement minimizes power loss. Delivering smooth drive and a light response.

Designed and configured with a dedicated part number for each vehicle model. We prioritize installation precision and feel, and offer a dedicated part number for each vehicle model, providing a better fit and performance.
