PROX Titanium Exhaust Valve (ref. 28.4350-1) — Designed for motocross riders who want reliability and lightweight components at the heart of their cylinder head. This PROX valve is made from titanium, a material known for its strength-to-weight ratio, and is forged from a single piece to minimize weak points and ensure consistent mechanical performance.
- Material: titanium, for reduced weight without compromising strength.
- Construction: forged from a single piece to enhance robustness in intensive use.
- Treatment: plasma coating to enhance thermal resistance and extend lifespan.
- Usage: recommended for engine tuning and suited to the demands of motocross.
- Packaging: sold individually.
This part is intended for demanding preparations and rebuilds; this PROX exhaust valve is aimed at riders looking for a reliable replacement part for their off-road sessions. Check compatibility with your model before installation — common fits include the Kawasaki KX 250 (2022-2024) and KX 250 X (2024) — and have a professional perform the installation for optimal adjustment of the moving assembly.
