§ 02 / About this part
What it is
The PROX VALVE EX TITAN YZF450, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This titanium exhaust valve is built for the demanding top-end of your YZF450. It sits in the exhaust port and handles extreme heat while maintaining low reciprocating weight. Titanium is essential for the high-revving nature of this engine. These valves are consumables in a race environment and must be replaced when clearances start to tighten consistently. The special coating on the valve face must remain intact. Never use lapping paste on these valves. Direct fitment ensures your bike maintains its factory power delivery.
