YAMAHA YZ450F 2010 - 2013 PRO-X STEEL EXHAUST VALVE & SPRING KIT YZF450
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.
Steel Valves for increased durability and less wear under extreme conditions
Features:
- Nitrided valves offer high microhardness while supersmooth surface finish reduces friction between stem and guide
- Special stronger valve springs deal with the extra weight of the steel valves
- Springs are made from premium Chrome Vanadium Steel for higher performance and durability at high RPMs
- Fully rebuild able with OEM retainers, bases and seals without the need of any further engine modifications
- Comes as complete package for quick, easy and cost efficient replacement
