§ 02 / About this part

What it is

Boyesen pro series carbon fibre reed petal to fit Yamaha YZ65 (2018–2026); Yamaha YZ85LW (2002–2026); Yamaha YZ85SW (2002–2026).

These carbon fiber petals sit inside your reed block between the intake and the cylinder. They control the fuel-air mixture entering the crankcase. Over time, petals chip or lose tension, causing poor starting and a bogging bottom end. This dual-stage design improves throttle response and crispness off the line. Replace these during your top-end rebuild for maximum performance. Ensure the reed cage surfaces are clean and flat before installation. These petals offer a direct replacement for your OEM setup. They are essential for maintaining peak power on race-tuned engines.

§ 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.
