§ 02 / About this part

What it is

The PARTS UNLIMITED 18" STANDARD BUTYL TUBE TR-4 STEM TYPE FITS 4.00/5.10 120/90, tubes. Stocked by Iron Offroad, the UK MX hard parts specialist.

Standard butyl rear tube. Fits 18" rims running 120/90 or 4.00/5.10 rubber, so it covers most enduro and trail setups. TR-4 stem clears the rim lock cleanly. Butyl holds pressure better than cheap aftermarket alternatives, which matters when you're checking sag in the van park at 6am. Swap it every second tyre change, sooner if the carcass is showing chafe marks or the patch count is climbing. Check the rim lock nut and the band tape before you fit it. Dust the carcass with talc on the way in. Tubes that scrub against dry rubber heat up, and hot tubes split.

§ 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.
