§ 02 / About this part

What it is

Vertex replacement piston ring set to fit Kawasaki KX100 (1998–2021); Suzuki RM85 (2002–2016); Suzuki RM85L (2003–2016).

Maintaining compression starts at the cylinder wall. These rings seal the combustion chamber and manage heat transfer from the piston to the bore. Wear is inevitable in high-hour engines, leading to blow-by and lost power. Replace these during every top-end refresh to restore factory performance. Always check your ring end gap in the cylinder before final assembly. Ensure any markings face the cylinder head to avoid oil migration or snagging a port. These are precision-engineered to match specific bore diameters and piston profiles for a reliable seal under race conditions.

§ 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.
