§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 47.95MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

47.95mm B-size kit for the Suzuki RM 85, cross-referencing OEM 12110-03B20-0F0. Piston, rings, gudgeon pin and clips in one box. On a small-bore two-stroke the top end is a service item, not a repair; race-pace 85s want a fresh piston every few hours of hard running. B sizing restores clearance in a cylinder that's seen use without going oversize. Mic the bore to confirm 47.95mm is right for it. Set the ring gap clear of the ports on assembly or you'll snag a ring.

§ 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.
