KTM 250SX-F Complete Valve Guide Set
description
Includes 4 valve guides. With a stop collar.
Works for 2014-2025 engines.
Our valve guides are precision-machined from the highest quality alloy, holding the tightest tolerances in the industry. Which means better 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.
