§ 02 / About this part

What it is

The Moose Offroad PISTON KIT HIGH PERFORMANCE 4-STROKE 14.7:1 BORE: 78 00 MM, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This high-compression top-end component increases torque and throttle response across the rev range. It replaces the stock unit during a routine rebuild or performance upgrade. The 14.7:1 ratio demands high-octane fuel to prevent detonation. Ensure your cylinder bore is measured accurately before installation. The kit includes the piston, rings, gudgeon pin, and circlips. Check your service manual for specific torque settings on the cylinder head bolts. Proper heat cycles are vital for bedding in the rings. This is a precision part for riders seeking more punch from their 4-stroke engine.

§ 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.
