§ 02 / About this part

What it is

The BOYESEN WATER PUMP COVER & IMPELLER KIT SUPERCOOLER ALUMINUM MAGNESIUM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Standard cooling systems can struggle under race conditions. This kit improves the flow rate of your coolant by using a redesigned impeller and housing. It sits on the lower engine case. The improved hydrodynamic design prevents the coolant from foaming at high engine speeds. This helps maintain stable operating temperatures during long motos. It is a direct bolt-on replacement for the factory parts. Always use fresh coolant and verify the pump shaft condition before reassembly.

§ 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.
