§ 02 / About this part
What it is
The FMF FATTY PIPE NICKEL-PLATED STEEL YAMAHA, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This expansion chamber broadens the powerband across the entire RPM range. It replaces your stock front pipe, sitting between the cylinder head and the silencer mid-pipe. The nickel-plated finish resists corrosion and provides a durable surface against roost and mud. It is designed to improve throttle response and increase over-rev on your two-stroke. Fitment is model-specific and uses your existing OEM mounting points and springs. Always check your jetting after installation to ensure the air-fuel mixture compensates for the increased flow. This is a standard upgrade for woods or track use where a more linear power delivery is required.
