§ 02 / About this part

What it is

The VERTEX ENGINE BOTTOM END YAMAHA REBUILD KIT, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit provides the essential components for a full bottom-end overhaul on your Yamaha. It includes the crankshaft, main bearings, and a complete gasket set. Bottom-end failure often manifests as increased vibration or a distinct knocking sound from the crankcases. This kit simplifies the rebuild process by grouping all necessary parts under one SKU. It is designed to meet OEM specifications for fit and balance. Ensure you have a clean workspace and the correct pullers before splitting the cases. Always lubricate the new bearings with assembly oil during installation.

§ 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.
