§ 02 / About this part

What it is

ProX top-end gasket kit to fit Gas Gas EX450F (2021–2024); Gas Gas MC450F (2021–2027); Husqvarna FC450 (2019–2027); Husqvarna FS450 (2019–2026); Husqvarna FX450 (2019–2024); KTM SMR450 (2021–2026); KTM SX-F450 (2019–2027).

Seal the top end of your bike during your next piston refresh. This kit includes the head gasket, base gasket, and the required O-rings for the cylinder and head. These components are critical for maintaining engine compression and preventing coolant from entering the combustion chamber. High-performance engines require fresh gaskets every time the top end is opened to ensure reliability. These parts are engineered to match the specific bore of your bike. Clean all mating surfaces and check for flatness before fitting the new gaskets.

§ 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.
