§ 02 / About this part

What it is

The FMF SPRING/O-RING KIT YAMAHA, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

These components seal the junction between your cylinder manifold and the expansion chamber. Heat cycles and constant vibration eventually perish the Viton O-rings, leading to oily residue and lost back-pressure. Exhaust springs lose their tension over time or snap during heavy landings. Replacing these ensures a gas-tight seal for consistent power delivery. This kit is a direct replacement for your worn hardware. Always clean the manifold grooves thoroughly before seating the new rings to prevent tearing. Use a dedicated spring puller for the install to avoid damage to the pipe or your knuckles.

§ 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.
