§ 02 / About this part

What it is

The PROX GASKET BASE+HEAD YZ125, gaskets & seals. Stocked by Iron Offroad, the UK MX hard parts specialist.

This set focuses on the core sealing components for a top-end refresh. It includes the cylinder head gasket and base gasket required to reassemble the top-end after a piston change. These parts are critical for holding compression and sealing the water jacket on liquid-cooled engines. Replace these every time the cylinder is pulled to avoid leaks or pressure loss. The gaskets are manufactured to match OEM dimensions exactly, ensuring correct squish clearance and port timing on your bike. Always check for flat mating surfaces before torquing down the head bolts.

§ 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.
