FMF Mini Moto Exhaust System — Kawasaki KLX140/KLX140L/KLX140G 2008–2026

Header and muffler tuned as one unit: broader pull out of corners, a lighter overall package, and the throttle response FMF's factory race team chases.

Fits: Kawasaki KLX140/KLX140L/KLX140G 2008–2026.

Why riders pick it:

• Purpose-built for mini bikes — sized and tuned for youth and mini-moto power delivery
• Lightweight full system trims weight off a bike where every pound matters most
• Smooth, predictable power delivery appropriate for new and younger riders
• Direct bolt-on installation, no tuning required

⚠️ For closed-course competition / off-road use only — not legal for street use in some states. Confirm your local regulations.
