The valve that lets the burnt gases out of the engine to the exhaust.
WISECO offers this exhaust valve for KTM EXC, MXC, SX, XC 400, 450, 520, 525 and POLARIS OUTLAW 450, 525 1999-2011. A four-stroke engine breathes through its valves. The exhaust valves open to let the burnt gases out to the pipe, then close again.
Titanium or steel valve?
The material is shown in the product name.
- Titanium: about 40% lighter than steel, it allows high revs without valve float; it costs more and its coating wears faster if the seats and guides are tired.
- Steel or stainless: heavier, but very wear-resistant and cheaper; as a replacement for titanium it lasts longer, with springs suited to its weight.
- Tip: replace valves as a set, have the seats checked and fit new valve stem seals.
Why choose WISECO?
Wiseco has forged its pistons in Mentor (Ohio, USA) since 1941 and controls the whole process, from aluminium bar to the friction-reducing ArmorGlide skirt coating. Its pistons are developed with Team Honda HRC in Supercross (450 class since 2018).
When should you replace the valves on your KTM EXC 450?
Hard hot starting, valve clearance that keeps closing up or a noisy timing chain: the valve train is wearing.
