§ 02 / About this part

What it is

The VERTEX PISTON KIT PRO HC TOP END Ø 47.50 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This high-compression component sits at the heart of your top-end rebuild. It replaces the factory unit to increase cylinder pressure and sharpen throttle response on your small-bore bike. This B-size kit accounts for minor cylinder wear on a seasoned bore. Always check your cylinder diameter with a micrometer before fitting to ensure the correct clearance. Regular replacement prevents catastrophic failure and maintains peak power during race season. Ensure you clean the power valve assembly while the head is off to ensure smooth operation across the rev range.

§ 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.
