FMF Factory Fatty Pipe 025222 — KTM / Husqvarna / Gas Gas 85cc 2018-2024

Product Description

The FMF Factory Fatty Pipe is the ultimate choice for riders seeking "works" pipe performance on their 85cc machine. Engineered to provide the same professional-grade craftsmanship and material quality found on factory race bikes, this expansion chamber is designed to significantly broaden and smooth out your power delivery.

Utilizing a lightweight 20-gauge steel body with a reinforced 19-gauge header, the Factory Fatty is built to perform under demanding race conditions. Through hand-pounded seams and precision flow engineering, this pipe delivers more low-end grunt, a stronger mid-range, and increased over-rev, giving you the power you need to clear jumps and pull ahead of the competition.

Frequently Asked Questions

Q: Will I need to jet my carburetor after installing this pipe?
A: Yes, because the Factory Fatty alters the engine's flow characteristics, re-jetting is required to achieve the correct air/fuel ratio and unlock the pipe's full performance potential.

Q: Is this pipe durable enough for off-road/trail riding?
A: Absolutely. While designed for racing, the steel construction is robust. However, as with all high-performance expansion chambers, it is susceptible to dents from rocks, so a quality pipe guard is highly recommended.

Expert Pro-Tip: To prevent surface rust on your raw steel Factory Fatty pipe, give it a quick wipe-down with a high-temperature pipe oil or WD-40 after every wash. This keeps the finish looking sharp and prevents oxidation from compromising the steel's integrity over time.
