§ 02 / About this part

What it is

The VERTEX FULL TOP END K550, gaskets & seals. Stocked by Iron Offroad, the UK MX hard parts specialist.

Top-end maintenance is a standard requirement for high-performance engines. This kit covers the cylinder head, base, and exhaust port seals needed for a piston swap or bore inspection. It eliminates the risk of coolant leaks or compression loss at the head-to-barrel interface. These gaskets are engineered to withstand the thermal stress of racing and trail use. Always check your squish clearance when installing a new base gasket to maintain optimal engine timing and performance. Replace these every time the cylinder is removed to ensure a reliable seal during your next rebuild.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
