§ 02 / About this part

What it is

Boyesen carbon fibre RAD valve to fit Honda CR125R (1992–1997).

This reed valve system replaces the entire OEM intake block to improve airflow velocity. It sits directly between your carburettor and the cylinder. The carbon fiber petals react faster than standard versions to sharpen throttle response across the rev range. Over time, petals can chip or lose tension, leading to difficult starting and a muddy bottom-end. This is a model-specific fitment designed to optimise the intake tract of your 2-stroke engine. Always use fresh gaskets during installation to prevent air leaks. It is a vital upgrade for any top-end rebuild or performance tuning.

§ 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.
