§ 02 / About this part

What it is

The PROX PISTON RING SET 78.00MM STANDARD, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This ring set is designed for a 78.00mm standard bore and cross-references with OEM part 3005-749. These components are vital for sealing the combustion chamber and managing heat transfer to the cylinder wall. Wear leads to compression loss and reduced engine efficiency. Replace these during every top-end service to restore factory power levels. Always check the ring end gap in the bore before installation. Ensure any markings face the cylinder head to prevent oil migration. These are engineered for a precise fit and long-term reliability.

§ 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.
