§ 02 / About this part

What it is

The Moose Offroad FF SPRING SET 43.5MM 5.4, fork springs. Stocked by Iron Offroad, the UK MX hard parts specialist.

Pick the 5.4 N/mm rate if you're an A-class or pro rider on a 250F and the stock springs pack down too far on hard braking. The 43.5mm tube spec drops straight into KX 250, KX 250F and RM-Z 250 forks. Set your race sag at 33-35mm, check static sag sits around 28-32mm, and tune compression from there. Heavier riders or anyone landing big doubles will feel the difference on the second corner — front end stays planted, forks hold up through the stroke, no harsh bottoming on chop. Fit them as a pair.

§ 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.
