Review HINSON RACING Mn/1na4 Complete Billetproof Clutch Kit For Yamaha fits YZ125 2005–2025

Introducing the Hinson Racing MN/1NA4 Billetproof Clutch Kit, meticulously engineered for the 2005-2025 Yamaha YZ125. This clutch system is the epitome of high-performance and durability, designed to maximize power delivery and withstand the rigors of competitive racing.

The heart of this kit is the lightweight, CNC-machined billet steel clutch hub. It boasts a larger diameter than stock, allowing for a more direct power transfer from the engine to the rear wheel. The hub is also drilled for weight reduction and features a 720-degree split engagement design, ensuring smooth and precise engagement.

The MN/1NA4 kit includes Hinson's renowned X-Ring Billet Clutch Plate. This plate features a high-tensile billet steel pressure plate and a 24-hour heat-treated billet steel drive plate. The X-Ring design provides superior grip and durability, while the lightweight construction enhances engine performance. Additionally, the plate is drilled for weight reduction and features a unique, angled clutch spring design for optimal engagement.

The clutch kit also includes Hinson's high-performance, 11-inch DID clutch baskets. These baskets feature a 520 O-ring chain and are designed to provide superior clamping force and even wear. The baskets are also lightweight and feature an open-end design for easy maintenance.

The MN/1NA4 Billetproof Clutch Kit comes with a complete set of Hinson's high-quality clutch springs. These springs are made from chrome silicon wire and provide superior clamping force and consistent engagement. The springs are also designed to be easy to install and adjust.

The Hinson Racing MN/1NA4 Billetproof Clutch Kit is not only a high-performance upgrade, but it's also built to last. The billet steel components are heat-treated for strength and durability, and the X-Ring clutch plate design ensures consistent grip and long clutch life. This clutch kit is a must-have for any serious Yamaha YZ125 racer looking to gain a competitive edge and improve reliability.
