§ 02 / About this part

What it is

Moose Offroad standard top-end gasket set to fit the KTM EXC 125, model years 2002–2006, and KTM SX 125, model years 2002–2006.

Fresh seals are mandatory when pulling the head and cylinder for a piston refresh or bore inspection. This kit provides the necessary components for a top-end rebuild, including base gaskets, head gaskets, and exhaust seals. Reusing old gaskets leads to compression loss or coolant contamination. These sets match OEM tolerances for your specific bike. Scrape away all old material from the mating surfaces before fitting. Always use a calibrated torque wrench on the head bolts to ensure an even seal across the bore. It is essential for your scheduled service interval.

§ 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.
