This component mounts to the rear of your swingarm to feed the chain onto the rear sprocket. It takes heavy abuse from rocks and deep ruts. Mud and grit accelerate internal wear on the wear block. Replace this when the side walls thin or the chain starts to drag. This part matches OEM dimensions for a direct swap. Use your existing hardware for installation. Ensure the chain runs central through the guide to prevent premature sprocket wear. It is a vital part for maintaining drive alignment during hard enduro or heavy MX landings.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. 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 and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
