At DMG Motorsports, we present the Vertex Water Pump Rebuild Kit 821276 — a complete, ready-to-install kit engineered to bring a tired water pump back to full performance without the hassle of tracking down individual parts. Built for the Honda CRF450X, this kit takes the guesswork out of a cooling system rebuild by bundling every gasket, seal, bearing, and washer you need into one convenient package. Whether you're maintaining a trail bike or prepping a race machine for the next season, this kit helps keep your engine running cool and reliable, mile after mile.

Vertex is a trusted name in gasket and seal manufacturing, and this rebuild kit reflects that reputation with quality components designed to match or exceed original equipment specifications. Instead of piecing together a rebuild from multiple sources, riders and technicians can grab this single kit and have everything required to restore proper sealing and function to the water pump assembly, helping to prevent coolant leaks and pump failure down the road.

Features:

• Complete kit includes inner clutch cover gasket, water pump cover gasket, and all bearings, seals, and washers required to rebuild the water pump
• Mechanical water pump seal included for a proper, leak-resistant rebuild
• Meets or exceeds OEM quality standards for dependable, long-lasting performance
• Designed specifically to fit the Honda CRF450X water pump assembly
• One convenient kit eliminates the need to source individual gaskets and seals separately
