WISECO Steel intake valve for KTM EXC 400 RACING, HUSABERG FE 450 E and POLARIS OUTLAW 525 IRS from 1999 to 2012

WISECO offers this steel intake valve for KTM EXC 400 RACING, HUSABERG FE 450 E and POLARIS OUTLAW 525 IRS from 1999 to 2012. A four-stroke engine breathes through its valves. The intake valves open to let the air-fuel mixture into the cylinder, then close perfectly tight during combustion.

Titanium, steel or stainless valve?

This valve is stainless steel.

• Titanium: about 40 % lighter than steel, it lets the engine rev high without valve float; standard on most modern 4-stroke motocross bikes. On the downside, it costs more and its coating wears faster if seats and guides are tired.
• Steel or stainless: heavier but very wear-resistant and cheaper; as a titanium replacement 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, the American engine specialist since 1941, forges and machines its parts in its Mentor, Ohio, plant.

When should you replace the valves?

Hard hot starting, valve clearance that keeps closing up or a noisy timing chain: the valve train is wearing.

Specifications and fitting tips

• Application: Intake
• Material: Stainless steel
• CVD or CNI treatment (depending on application); both processes reduce wear and friction and resist heat

Cross-Mania tip: Check the guides and seats before reassembly and lap the valves in. Titanium valves must not be fitted on worn seats.
