Yamaha YZ450F, YZ450FX, and WR450F Water Pump Impeller Spacer Kit with Gasket, Direct Replacement

Upgrade your Yamaha YZ450F, YZ450FX, or WR450F with a precision-made Water Pump Impeller Spacer Kit with Gasket. This direct replacement kit is designed to improve cooling efficiency by increasing coolant flow through the water pump. With enlarged impeller vanes, the system moves more coolant at the same engine speed, helping reduce coolant temperatures by 10-15°C and preserve engine performance during tough riding, long motos, or race sessions.

Crafted from premium 6061-T6 aluminum, this spacer kit is lightweight yet durable enough to handle demanding terrain. The anodized surface keeps the finish looking sharp ride after ride, while CNC machining ensures precise tolerances for easy installation and a clean fit. It’s a true race-inspired upgrade that doesn’t require extensive modification—just a direct replacement that maintains factory reliability while delivering a performance edge.

Compatibility is straightforward: for Yamaha YZ450F (2014-2022), YZ450FX (2016-2024), and WR450F (2016-2024). This kit, produced by S2R, is designed to install cleanly on listed models, providing improved cooling without sacrificing reliability or longevity. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
