FMF FACTORY FATTY PIPE for YAMAHA YZ 85YZ85 / part number 024039
Fits: YZ85 (2002 to 2019 models)
The FACTORY FATTY is reminiscent of the “works” or cone pipe once used by Factory Teams. It shares many of the same characteristics with its’ craftsmanship and material quality.
The Factory Fatty broadens and smoothes out the power curve while boosting gains throughout the entire power band, more low-end, more mid, and increased over-rev. No matter what type of riding you do, the Fatty has the benefits you’re looking for.
- Lighter 20 gauge steel used for the body of the pipe.
- 19 Gauge steel used for the header portion.
- Includes O-rings on most models
- Hand pounded seams for smooth flow transitions.
