§ 02 / About this part

What it is

The FMF HEADER TI MGBMB YZ450F, mid pipes. Stocked by Iron Offroad, the UK MX hard parts specialist.

This titanium header is engineered specifically for the YZ450F to boost low-end torque and mid-range pull. It sits at the exhaust port and uses a unique internal chamber to increase surface area. This design reduces sound output while maintaining top-end power. The titanium construction offers a major weight reduction compared to the stock Yamaha part. Replace your header if it is crushed or if you want a broader powerband. Always fit a new exhaust gasket to prevent leaks. It integrates perfectly with your existing silencer or an aftermarket slip-on.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. Brands you'd find on a paddock workbench; pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere. Dirt & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
