Our most Factory pipe available! The Factory Fatty is reminiscent of the “Works” or "Cone" pipes once used by Factory teams and shares many of the same characteristics with its craftsmanship and material quality. Boost power throughout the entire RPM curve for more low-end, more mid, and increased over-rev. The Factory Fatty broadens and smoothes out the YZ250's power curve just like the standard Fatty pipe but sports a Factory raw look.
