§ 02 / About this part

What it is

The VERTEX PISTON KIT REPLICA Ø 77.00 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This B-size replica piston kit cross-references with OEM 1SM-116A0-01-00. It sits in the top-end and includes the piston, rings, pin, and circlips. The B-sizing is designed for cylinders that have seen some use, ensuring the correct clearance is maintained. This kit is essential for restoring the factory performance of your bike. Measure your bore with a micrometer to confirm the 77.00mm B-fitment is correct. Check the ring end gaps and ensure the oil rings are correctly layered. Always follow the specific torque sequence for the cylinder head during assembly.

§ 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.
