VERTEX Titanium Exhaust Valve - Ref. 8400009-1
Designed for demanding engine preparations, this VERTEX exhaust valve is made from forged titanium and features a plasma-sprayed surface treatment. The result: a part that is better able to withstand thermal stress and wear compared to standard valves, while maintaining the precise fit required for engine operation.
Ideal for riders looking to enhance a modified cylinder head or replace an original valve with a high-quality part. To be installed during an engine overhaul or preparation, this valve can handle the typical stresses of off-road and sporty road use.
Known compatibilities (examples): SUZUKI DR-Z 400 SM (2017), KAWASAKI KLX 400 R (2004), SUZUKI DR-Z 400 S (2014). Please check the diameter and manufacturer reference before ordering to ensure proper fitment.
