§ 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.

A 43.5mm fork spring set at 4.2 N/mm, one step up from the base rate. That increment is enough to firm up the front for a mid-weight rider or harder tracks without going full stiff. Springs set ride height and bottoming resistance; clickers only manage the damping around them. Fits the same wide 43.5mm group as the rest of the set: Beta RR, Honda CRF, Husqvarna, Kawasaki KX, Sherco SC, Suzuki RM-Z. Confirm the rate against your gear-on weight using rider sag, then rebuild with fresh fork oil to keep damping consistent through the stroke.

§ 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.
