At DMG Motorsports, we present the Vertex Water Pump Rebuild Kit 821278 — a complete, OEM-quality solution designed to restore the cooling system on your 2002-2008 Honda CRF450R. Water pumps rely on tight-fitting seals and gaskets to keep coolant circulating and your engine running at the correct temperature. Over time these components wear out, leading to leaks and reduced cooling efficiency. This Vertex kit gives you everything needed to rebuild the pump correctly the first time, without the expense of replacing the entire assembly. Trusted by riders and mechanics alike, Vertex is known for producing precision-engineered gaskets and seals that hold up to the demands of off-road racing and everyday trail riding. Whether you're prepping for race day or performing routine maintenance, this rebuild kit helps keep your CRF450R's cooling system sealed tight and performing reliably.
