The RFX Pro Series ST Rear Brake Lever is engineered and tested for demanding off-road riding. Designed for Yamaha motorcycles, this blue solid-tip brake lever combines durable construction, impact-resistant features, and precise OEM-style fitment. RFX manufactures the lever from 7075-T6 aerospace aluminum, providing high tensile strength while keeping the design lightweight and responsive.
The forged shaft features a smooth finish that helps minimize surface wear commonly associated with ridged designs. Its CNC-machined billet aluminum tip is spring-loaded and rotatable, allowing it to spin during impacts in ruts and other challenging terrain. Steel insert teeth improve boot grip in muddy conditions, while the integrated mechanical stop limits rotation to 90 degrees to help protect the lever from excessive movement. A built-in cable brake snake adds further protection by helping prevent shaft bending during collisions.
Color anodizing helps resist corrosion, and the laser-etched RFX logo provides a clean, durable finish. The RFX Pro Series ST Rear Brake Lever is a practical upgrade for riders who need dependable rear-brake control and added protection in demanding environments. Part number FXRB 40101 99BU identifies this blue solid-tip Yamaha application.
