DescriptionProx Titanium Exhaust valve

Product details :

Features

PROX Titanium Exhaust Valve (manufacturer part number: 28.6343-1): a valve designed for motocross engines where strength and lightness are sought. Forged from a single piece of titanium, it combines mechanical resistance and reduced weight to withstand high RPMs and the demands of engine modifications.

Material: forged titanium
Single block forging for better homogeneity
Plasma coating for increased thermal resistance and improved longevity
Recommended for engine modifications
Sold individually

Suitable for high-performance motocross setups, this PROX exhaust valve integrates into head work and modifications when aiming to optimize the reliability of moving parts. Its lightweight design minimizes the inertia of the distribution elements, while the plasma coating protects the stem and head against thermal wear. Supplied individually, this component allows for targeted replacement during maintenance or modifications.

Common applications include: HUSQVARNA FC 250 (2025), GAS GAS MC 250 F (2025), and KTM 250 SX‑F (2024). Please check the exact compatibility with your model before ordering.
