§ 02 / About this part

What it is

Boyesen carbon fibre RAD valve to fit Yamaha YZ125 (2005–2027); Yamaha YZ125X (2020–2027).

This performance intake block replaces the OEM reed cage for better throttle control. The carbon fibre petals are designed for high-frequency vibration and rapid response. It smooths out the airflow into the cylinder for more consistent power. This valve is a critical component for any tuned two-stroke engine. It installs easily between the carb and the intake port. Ensure the mounting surfaces are clean to prevent air leaks. Inspect the petals for fraying at every service interval to maintain the integrity of the intake charge.

§ 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.
