VERTEX Steel Intake Valve for HONDA FMX 650 FUNMOTO, XR 600, XR 650, XR 650 L 1985-2012

VERTEX offers this intake valve for HONDA FMX 650 FUNMOTO, XR 600, XR 650, XR 650 L 1985-2012. 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 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 VERTEX?

Vertex has manufactured in Italy since 1953 and has supplied KTM’s original pistons since 1996 (KTM, Husqvarna, GASGAS), with ISO 9001-certified production.

When should you replace the valves on your HONDA XR 650 L?

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