Ferrea 09-12 Honda CRF 450 31mm Head Dia Competition Exhaust Valve - Set of 2

This listing is for a set of two Ferrea Competition Exhaust Valves, designed for 2009-2012 Honda CRF 450 models. These valves feature a 31mm head diameter, which is larger than stock, helping to improve exhaust gas flow out of the combustion chamber. When you're rebuilding the top end of your CRF 450, especially if you're looking for improved performance, these valves are a solid option.

Ferrea is known for making well-built valvetrain components. These competition valves are made from strong materials to handle the demands of an engine that's being pushed. The larger head diameter is a key feature that allows more exhaust to escape, which can contribute to better overall engine breathing and power output. Installing these is typically done during a full engine overhaul or cylinder head service.
