- The Factory Fatty is reminiscent of the “works” or cone pipe once used by Factory Teams and it shares many of the same characteristics with its craftsmanship and material quality
- Broadens and smooths 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
- Hand pounded seams for smooth flow transitions
