DESCRIPTION
The FMF Factory Fatty Expansion Chamber isn’t just another pipe it’s a throwback to the iconic “works” or cone-style exhausts once bolted onto full-blown factory race bikes. Built with the same craftsmanship and race-focused design, the Factory Fatty delivers broad, usable power across the entire rev range with more low-end torque, a stronger midrange, and impressive over-rev for when it’s time to let the 2-stroke sing.
Whether you’re shredding trails, lining up for moto, or hitting technical terrain, the Factory Fatty gives your engine the smooth, responsive power delivery you need and that raw, race-bike look you’ll love.
Supplied by Motozone NZ, where performance lives and breathes 2-stroke.
~ Inspired by Factory “Works” Pipes, with raw cone-pipe styling and race heritage
~ Broader, Smoother Power Curve, gains across low, mid, and top-end
~ 20-Gauge Lightweight Steel Body, reduces weight while maintaining strength
~ 19-Gauge Header Section, tougher where it counts for durability
~ Hand-Pounded Seams, ensures smoother flow transitions and tuned performance

~ Unplated Factory Finish, looks raw and ready, like a true race machine
~ Made in the USA, precision-engineered by FMF Racing
Whether you're chasing holeshots or railing berms wide open, the FMF Factory Fatty Expansion Chamber delivers bottom-end grunt to top-end pull that begs to be revved. Purchase at Motozone New Zealand your 2-stroke performance HQ.
