Product Description
The Factory Fatty is reminiscent of the “works” cone pipes once used by factory teams and shares the same craftsmanship and material quality FMF is known for. It broadens and smooths the power curve while delivering gains across the entire power band with stronger low-end, improved midrange, and increased over-rev. No matter the riding style, the Factory Fatty delivers noticeable performance benefits.
