FMF MegaBomb Header — Kawasaki KX250F / KX250X 2021–2024

A header built around FMF's resonance chamber design, widening the powerband and setting up whatever slip-on you run behind it.

Fits: Kawasaki KX250F / KX250X 2021–2024.

Why riders pick it:

• Resonance chamber design broadens midrange power and pull out of corners
• Available in stainless or titanium construction depending on the kit
• Pairs perfectly with a Factory 4.1 or Q4 muffler for the full effect
• Direct bolt-on installation, no tuning required
