Product details :

Features

VERTEX Titanium Intake Valve (manufacturer part number 8400057-2) — a machined intake valve designed for engine tuning, intended for the Cross and Roadster environments. Forged from titanium and featuring a plasma coating, this valve offers a combination of lightweight construction and durability against the thermal stresses encountered in intensive use.

Material: forged titanium — a strength-to-weight compromise suitable for high RPMs
Treatment: plasma coating for improved wear and heat resistance
Designed for engine tuning and competitive use
Sold individually

Ideal for cylinder heads subjected to high demands, the VERTEX valve is aimed at riders seeking reliable components for the camshaft, valve seat, and intake system. Its alloy and treatment make it a suitable option for tuning work, where robustness and long-lasting endurance are essential.

Among common applications, it is particularly suitable for recent 450cc models such as the KTM 450 SX-F (2025), HUSQVARNA FC 450 (2025), and GAS GAS MC 450 F (2025). Please check the exact compatibility with your cylinder head before installation.
