Factory Fatty Pipe – ’02-’18 YZ85

The FMF Factory Fatty Pipe is designed to deliver exceptional performance for Yamaha YZ85 models from 2002 to 2018. Crafted with high-quality materials, this exhaust pipe mimics the classic “works” or cone pipe used by professional factory teams, ensuring optimal craftsmanship and durability. The Factory Fatty enhances your bike’s power delivery by broadening and smoothing the power curve, resulting in increased torque at low and mid-range RPMs, along with improved over-rev capabilities. This makes it ideal for a variety of riding styles, whether racing, trail riding, or recreational fun. The pipe is constructed using lightweight 20-gauge steel for the body, reducing overall weight without sacrificing strength, while the header section is made from 19-gauge steel for added durability. Hand-pounded seams facilitate smooth flow transitions, minimizing turbulence and maximizing exhaust efficiency. The overall design ensures better throttle response, increased horsepower throughout the entire RPM range, and a more aggressive sound. Easy to install, the FMF Factory Fatty Pipe is a proven upgrade that boosts performance and reliability, giving your Yamaha YZ85 the competitive edge it needs. Whether you’re aiming for better race results or enhanced trail performance, this pipe provides the benefits you’re looking for in a high-performance exhaust system.
