§ 02 / About this part

What it is

ProX top-end gasket kit to fit the KTM SX-F 450, model years 2007–2012.

A top-end rebuild requires a fresh seal to maintain compression and prevent coolant migration. This kit provides the head gasket, base gasket, and necessary O-rings for your cylinder and head assembly. Use these when replacing your piston or rings to ensure the combustion chamber remains airtight. Always clean the mating surfaces of the cylinder and crankcase thoroughly before installation. Check your workshop manual for the specific torque sequence on the head bolts. These components match OEM specifications for a precise fit on your engine. Proper sealing here is critical for consistent power delivery and cooling efficiency.

§ 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.
