§ 02 / About this part

What it is

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

Vertex's bottom-end kit for the Honda CR85R and CR85RB: complete crankshaft, main bearings, crank seals and the full gasket set for splitting and resealing the cases. Small-bore two-strokes rev hard, and the CR85's big-end takes the punishment first. Rock the rod side to side at TDC and any detectable play means the crank is done. Rather than pressing a new rod into a tired assembly, this drops in a fresh crank on new mains in one job. Clean the cases, check the transfer ports for debris from the old bearings, and torque the cases evenly on assembly.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
