§ 02 / About this part
What it is
FMF Factory Fatty raw steel exhaust pipe to fit Yamaha YZ85LW (2002–2018); Yamaha YZ85SW (2002–2018).
This raw steel expansion chamber delivers a true works-spec power curve with improved tractability. The lighter gauge steel allows for better resonance and weight reduction. Because it lacks a plated finish, you must oil the surface after washing to prevent surface rust. It is hand-welded to ensure smooth internal transitions for optimal gas flow. This pipe is built for racers who prioritise performance and weight over low-maintenance finishes. Replace your copper crush washer or O-rings at the cylinder head to prevent leaks that can lean out your jetting.
