§ 02 / About this part

What it is

The Moose Offroad FF SPRING SET 43.5MM 4.2, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Moose's 4.2 N/mm coils suit heavier riders or hard-pack tracks where the stock setup blows through its travel. They drop into the 43.5mm WP tubes on Husqvarna's FC 250, FC 350, FC 450, FE 450 and FE 570, so the fit is direct. Expect a firmer hold under braking and a steadier platform mid-corner. Set static sag around 30-35mm and race sag in the 100-105mm window before you touch clickers. Pair them with fresh fork oil at the height your manual specifies. If you ride sand or deep loam, run the harder end of the sag range.

§ 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.
