YAMAHA YZ250F 2001 - 2013 PRO-X STEEL INTAKE INLET VALVE & SPRING KIT YZF250

The Pro-X Steel Valve & Spring Kit are offered as an alternative to the OEM Titanium valves. Steel Valves last longer and require less adjustment than titanium valves.

Pro-X has now developed the Steel Spring Kits, containing a set of steel plus a set of specially designed stronger valve springs. The Pro-X kit just replaces the OEM valves & valve springs and can be installed using the OEM retainers, bases and valve seals.
