Wiseco Steel Intake Valve for Honda CRF70F 2004-2012 and XR70R 1997-2003 VIS022

Your Honda CRF70F or XR70R's intake valve is working harder than OEM specs allow, especially in high-rpm racing or extended performance sessions. A worn or stock valve will compromise combustion efficiency, increase friction losses, and accelerate engine wear—costing you power and longevity. The Wiseco VIS022 replaces that weak link with a precision-engineered component backed by advanced surface treatments that racing engines demand.

Built for serious riders and builders who refuse to leave performance on the table, this intake valve combines durability with measurable efficiency gains. The CVD or CNI coating technology reduces friction while resisting extreme heat—keeping your engine reliable whether you're racing competitively or pushing your bike hard on the street. You get the reliability of a trusted manufacturer with the performance edge needed for competition or high-stress applications.
