FMF Factory Fatty Pipe 025198 — KTM 65 SX / Husqvarna TC65 / Gas Gas MC 65 2016-2023

Product Description

The FMF Factory Fatty Pipe brings the iconic "works" performance and craftsmanship of professional factory team pipes to your KTM 65 SX, Husqvarna TC65, or Gas Gas MC 65. Designed for riders who demand the absolute best, this pipe is built with meticulous attention to detail and premium materials that set it apart from standard aftermarket exhaust systems.

This pipe is specifically engineered to broaden and smooth out the power curve, providing a noticeable increase in power across the entire RPM range. Whether you need more low-end grunt for tight corners, a stronger mid-range pull, or increased over-rev for the straights, the Factory Fatty delivers. Featuring a lighter 20-gauge steel body, a robust 19-gauge header, and hand-pounded seams for optimal flow transitions, this is the ultimate upgrade for any 65cc racer.

Frequently Asked Questions

Q: What is the main difference between the Gold Series Fatty and the Factory Fatty?
A: The Factory Fatty features the raw, unplated "works" finish and hand-pounded seams that mimic the pipes used by factory teams. It is built to be slightly lighter, while the Gold Series Fatty features a nickel-plated finish for enhanced corrosion resistance.

Q: Is the unplated finish prone to rust?
A: Yes, because the Factory Fatty has a raw steel finish, it is susceptible to surface rust if not maintained. We recommend spraying it down with a light coat of WD-40 or a specific exhaust cleaner after washing the bike to keep it looking factory-fresh.

Expert Pro-Tip: Because this is a raw-steel "works" pipe, it will change color as it heats up, turning a beautiful golden-bronze hue. This is completely normal and desired by factory riders! To prevent heavy rust, always dry the pipe thoroughly and apply a light oil coating after cleaning. Never let a wet bike sit in the garage, especially after riding in muddy or wet conditions.
