Wiseco Steel Valve Kit Honda CRF450R 2002-2006 SVKB1403

High-mileage CRF450R engines demand valve components that can withstand aggressive riding conditions and frequent maintenance cycles. The Wiseco Steel Valve Kit SVKB1403 delivers OEM-quality intake and exhaust valves paired with precision springs engineered to handle sustained load and thermal stress. This complete matched set eliminates the guesswork of sourcing individual components and gets your bike back to peak performance with minimal downtime.

What sets this kit apart is the inclusion of moly paste—a critical detail that reduces friction between cam lobes and buckets, protecting your valvetrain during break-in and extending overall service life. Whether you're refreshing a tired top-end or building a stronger engine, this kit provides the reliability you expect from Wiseco without the premium pricing of race-only alternatives.
