§ 02 / About this part

What it is

ProX countershaft seal kit to fit Honda CR250R (1988–2007); Honda CR500R (1988–2001); Honda CRF250RX (2019–2027); Honda CRF450L (2019–2020); Honda CRF450R (2002–2023); Honda CRF450RX (2017–2026); Honda CRF450X (2005–2015).

This kit provides everything needed to stop oil leaks behind the front sprocket. It contains the oil seal, O-ring, and the hardened bush that sits on the output shaft. Constant exposure to chain grime and pressure from the drive system eventually scores the bush and degrades the seal. A failing countershaft seal can lead to rapid oil loss and potential gearbox failure. This is a direct replacement for the factory components. Clean the countershaft thoroughly before sliding the new bush into place to ensure a proper seat.

§ 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.
