Compatible with Yamaha WR450F YZ450F YZ450FX intake manifold carburetor connection, original part number 2S2-13597-00, for off-road motorcycles.

This product is a genuine Yamaha intake manifold carburetor fitting (also called an intake hose), specifically designed for modern, high-performance Yamaha four-stroke off-road motorcycles: WR450F, YZ450F, and YZ450FX. The original part number is 2S2-13597-00. This component is a vital, flexible seal that connects the carburetor (or throttle body) to the cylinder head, withstanding the high intake pulsations and temperatures of a high-compression, single-cylinder engine. Manufactured to exacting competition standards from premium, reinforced materials, this product provides a reliable, durable, and high-performance repair and replacement solution for motorcycles whose rubber has deteriorated due to harsh operating conditions. It is an essential component for restoring throttle response and strong low-end torque to these powerful off-road motorcycles. Key features include precise compatibility with off-road models: Specifically designed for Yamaha 450cc off-road/endurance/racing motorcycles, it ensures a perfect fit with respect to the engine bay configuration and fuel injection system (carburetor or electronic) of each model. A faithful reproduction to competition specifications: Based on part number 2S2-13597-00, this component faithfully reproduces the complex shape of the internal air duct, the outer contour, and the mounting points for a perfect fit on the cylinder head and intake system. Engineered for extreme conditions: Given the high temperatures, strong vibrations, and heavy loads characteristic of off-road motorcycle engines, this product utilizes a specially formulated, reinforced silicone. This provides exceptional resistance to impact, aging from heat and oxygen, and corrosion from fuel additives, significantly surpassing conventional rubber parts. Restoring Off-Road Responsiveness: On large single-cylinder engines, any leak in the intake system leads to a significant loss of low-end torque and imprecise throttle response. Replacing this part ensures a perfect intake seal, allowing the fuel system to operate precisely and restoring spontaneous responsiveness and optimal engine control in challenging terrain. Durability Guarantee: Ensures a reliable seal even during intensive and prolonged off-road use, reducing the risk of breakdowns in the wilderness due to component failure. Compatibility: Fits Yamaha WR450F, Yamaha YZ450F, Yamaha YZ450FX
