The valve that lets the air-fuel mixture into the engine, then seals the combustion chamber.
KIBBLEWHITE offers this intake valve for HONDA CRF 450 X from 2005 to 2018. 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 KIBBLEWHITE?
Kibblewhite Black Diamond valves are forged in one piece from stainless steel, machined and surface-treated in the USA: a highly wear-resistant valve.
When should you replace the valves on your HONDA CRF 450 X?
Hard hot starting, valve clearance that keeps closing up or a noisy timing chain: the valve train is wearing.
