The RK 7084-070EX Chain and Sprocket Kit is an OEM replacement drivetrain solution designed for Triumph 865 Thruxton motorcycles from 2007 through 2015. This complete kit includes OE gearing to help preserve the motorcycle’s original performance characteristics, acceleration response, and cruising behavior. It is engineered for riders seeking a reliable, high-mileage replacement kit with components matched for proper fitment and drivetrain compatibility.
The kit features a premium Driven® C45 steel alloy rear sprocket with a black case-hardened finish, paired with a Driven® C45 steel front sprocket that is case hardened and quenched for enhanced durability. These materials and treatments help the sprockets withstand the repeated loads, friction, and wear associated with street riding. The natural-finish RK chain completes the assembly and provides a practical replacement for worn or aging original-equipment components.
Designed and manufactured by RK, the 7084-070EX is a direct-fit application for the Triumph 865 Thruxton model years 2007–2015 when replacement components with OE gearing are required. Confirm motorcycle year, model, and existing drivetrain specifications before installation. Professional installation is recommended, including correct chain adjustment, sprocket alignment, and final fastener torque.
