The FMF Factory Fatty Pipe is designed to deliver an all-around power increase throughout the power range of compatible Yamaha YZ65 motocross motorcycles. Its performance-focused design helps provide responsive power delivery for riders seeking improved engine output across a broad range of riding conditions. This FMF exhaust pipe is engineered specifically for the Yamaha YZ65 platform and is a direct-fit performance upgrade for properly equipped applications.
Built with durable construction, the FMF Factory Fatty Pipe uses electro-nickel plating for a non-chip finish that resists discoloration during normal use. The plating helps maintain the pipe’s appearance while providing a durable exterior suitable for the demands of motocross riding. Unlike the plated pipes, the Factory pipe features hand-pounded welds and no coating, matching the functional appearance and construction style associated with FMF works bikes.
Fitment includes 2018 through 2026 Yamaha YZ65 models. The manufacturer part number is FMF 024069, and the vendor part number is 78-1315F. Verify the motorcycle year and model before installation to ensure compatibility. Professional installation is recommended, and all mounting hardware, exhaust seals, and related components should be inspected before use to support proper fit and performance.
