Honda CRF250R Complete Valve Guide Set
description
Works for 2022-2025 engines. Includes 2 intake and 2 exhaust valve guides.
Our valve guides are precision-machined from the highest quality alloy, and ensuring the tightest tolerances in the industry. The result: improved valve sealing and longer lasting components.
Moldstar® 90 alloy outperforms manganese bronze and C630 in every way. Providing great lubricity and extreme resistance to ovality and frictional wear. It has the same thermal conductivity as cast aluminum, which is 4x that of C630. Making it the best alloy for high power density applications, especially when paired with Titanium valves.
