ORC N1 Clutch Series
The N1 Clutch is a high-performance racing clutch designed specifically to comply with JAF N1 regulations. Engineered for the demands of competitive racing, it delivers superior torque transmission, durability, and responsiveness. Whether for circuit driving or intense competition, the N1 Clutch offers precise control and reliable performance, ensuring drivers stay ahead in the race while meeting strict regulatory standards.
QUICK SHIFT FEELING: The N1 Cutch Series uses an exclusive lightweight metal clutch disc.
By using a three-part metal material construction, the inertia of the disc is reduced and a racing feel is achieved when shifting. Metal with high friction material is used to ensure reliable torque transmission, while losses during shift changes are minimized.

Due to the nature of the product, the ORC clutch is designed to be "lightweight and have low inertia", so compared to stock products, the rattling noise of the transmission standby gear is more likely to be transmitted in some cases.
The noise is caused by the internal structure of the transmission, and there is no problem with the quality or performance of the clutch.
