§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 47.00MM STANDARD, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Standard 47.00mm bore kit for Honda's 70cc singles: C70, CT70, XR70R and CRF70F. Cross-references OEM 13101-GCF-A20. Piston, rings, gudgeon pin and circlips in the box. These little four-strokes run forever, but the top end still wears, and a fresh piston brings back compression and first-kick starting. Measure your bore before ordering. If it's past standard spec, rebore and take the 47.50mm oversize instead. Decoke the head while it's apart; carbon build-up on a small bore costs more than you'd think.

§ 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.
