§ 02 / About this part

What it is

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

Vertex's lower-end rebuild for the KTM 85 SX, both the 17/14 and 19/16 wheel variants. You get a complete crankshaft with rod fitted, main bearings, crank seals and the gaskets needed to split and reseal the cases. A complete crank beats a rod kit for most home builds: no press work, no truing, just fit and go. On a raced 85 SX the sensible schedule is a bottom end every second top-end, because a failed big-end at peak rpm rarely stops at the crank. Measure runout on installation and prime the mains with two-stroke oil before first start.

§ 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.
