IRON STABLE — the Harley parts shop that finally made sense of the diagrams

A Yorkshire-based online parts house with the brand list of a dealer counter, a stockroom the size of a small county, and a parts-finding tool that actually shows you what fits. We had a proper poke around so you don’t have to. The walk-through is up on our YouTube channel — we’ve embedded it below for you to watch.

Anyone who’s tried to keep an older Harley running in this country knows the routine. You ring round three dealers. Two of them put you through to voicemail; the third tells you to hold while they “have a look on the system”, and the part you’re after turns out to be a 1989 supersession that was last seen on a microfiche somewhere outside Milwaukee. Forty minutes later you’re back where you started — except now you’ve got the local radio’s hold music stuck in your head and a cold cup of tea staring at you.

We got asked to check out IRON STABLE (https://ironstable.app) “have a look at this, it’s a bit different!”, we were expecting another catalogue site with a search bar, a stock photo of a Road King, and the same five aftermarket brands we’ve all seen a hundred times. What we found instead is one of the more genuinely useful pieces of bike-shop kit we’ve come across in a while. There are two halves to it, and the order matters, so we’ll take them in turn.

The diagrams: their best trick

This is the bit they’ve clearly put the work in on, and it’s the bit nobody else in the UK (or the EU & USA for that matter) seems to do properly.

You pick a model family — Sportster, Dyna, Softail, Touring, V-Rod, the lot, all 33 of them, all the way back to the bikes most dealers have politely forgotten exist. Pick your model code. Pick your year. From there you get every factory assembly diagram for your bike — brakes, engine cases, primary, electrical, frame, the whole catalogue split out the way the dealer’s parts computer splits it. Click any callout on the diagram and you get the official HD part number, superseded history, current availability, the price in sterling with VAT, and — and this is the part that earned a small “oh, that’s clever” out of the office — the any aftermarket alternatives sitting right next to it, on the same row.

If you’re trying to find a clutch hub bearing for an ’02 Dyna, you’re not having to bounce between a parts diagram on one tab, an HD number search on another, and a punt at whether EBC’s part is the right one on a third. It’s all on the same line. James gaskets, EBC pads, Galfer rotors, TRW shoes, Goodridge braided lines, Drag Specialties replacements — wherever there’s a credible aftermarket alternative for the OEM part, it’s there. Wherever HD has discontinued a number and replaced it with another, the diagram already knows. You’re not chasing a dead part-number through the internet at half eleven on a Sunday night.

The clever bit — and it’s worth saying this plainly, because it’s not the kind of thing a site tends to brag about — is that this is their own data, mapped in-house. It is not someone else’s parts feed bolted onto a shop front. They’ve built the diagrams, they’ve built the cross-references, visual represented the parts onto image cards. That’s why it works in a way that the other “search by HD part number” tools you might have used don’t. Old bikes, new bikes, half-discontinued bikes — it doesn’t matter; if HD made the diagram, IRON STABLE has it, and the parts on it are priced and in stock or they aren’t.

For anyone running a Shovel, an Evo, a Twin Cam, or one of the early M-8s where the dealer network is distincly hazy about what’s actually available, this is the bit of the site that will save you the most time. Bookmark https://ironstable.app/part-finder/.  That’s the door. If they dont have it they also offer a check service you submit a ticket. Their backend system checks all UK Harley-Davidson dealer stock (whats left of the network!) and then hits you up in a few days if another dealer has it and they can see it showing in stock, oh and that’s for free no middle man no commission.

The upgrade & customisation side: when you’re building, not fixing

The other half of the shop is for when you’ve already got the bike running and you’ve started staring at it on a Sunday morning thinking “right, what next?” This is where IRON STABLE’s brand list opens out into something that reads a lot more like a parts-dealer’s wall than a website’s dropdown menu.

A quick scan, off the top of the head, of brands we recognised and pulled rails from:

For the engine and the noise it makes — Vance & Hines (the UK’s default Stage 1 exhaust pick — slip-ons, the 2-into-1 Pro Pipe, Power Duals, the VO2 Falcon intake, the Fuelpak FP4 tuner if you want the whole job in one box), S&S Cycle (the name, top to bottom — air cleaners, cams, big-bore kits, complete crate engines), Cobra, Freedom Performance, Rinehart Racing, Trask Performance for the turbo brigade, Jims, Feuling, Andrews, Dynojet, Screamin’ Eagle for the dealer-warranty-preserving route.

For the bike’s character — Arlen Ness, deep enough that you could spec an entire bike out of one brand and not run out of options; Roland Sands Design; West Coast Choppers; Biltwell for bars, helmets, grips, and basically the whole bobber starter kit; Burly Brand for the Dyna and bagger crowd; Kraus for top trees and bar risers; Paughco if you’re still chasing the proper chopper look; Joker Machine, Cult-Werk, HeinzBikes, Thrashin Supply — pick your decade and your scene, it’s in there.

For where you sit and what you carry — Le Pera and Mustang for seats that don’t ruin a 200-mile day, Saddlemen for seats and luggage that match, SW-Motech with the proper job for racks, panniers and tank bags if you’ve gone the touring direction, National Cycle and Memphis Shades for screens, Kuryakyn for the bolt-on dress-up that BSH readers were doing in 1996 and are still doing now because it still works.

For stopping — EBC, Galfer, Brembo, TRW, Goodridge braided lines as standard. For the chassis — Öhlins, Progressive Suspension, Performance Machine wheels and controls, Ride Wright Wheels if you want the spoked custom look.

For lighting and the dash — Custom Dynamics, Kellermann, Motogadget when you’ve decided to ditch the stock clocks and start again.

For tyres — Dunlop, Michelin, Metzeler, Pirelli, Continental, Avon. All of them, in the sizes you’d expect, with the fitments listed for your bike.

We’re stopping the list there because well to be honest we have to stop the list somewhere! There are now 477 brands live in the catalogue, we literally ran out of time checking this would have ended up the longest article we have ever written! The total parts count, last time we checked it before going to print, was 112,776 individual lines. That is a lot of nuts and bolts and it seems go up each time we check it.

What it costs, what arrives in the box?

Pricing is in pounds, VAT included. Free UK delivery over £100, which most engine-side orders clear without trying. There’s a member tier called Iron Pass for £25 a year that knocks the price down across the whole shop — worth doing on a single decent order or your an cusomisation king! When a part lands, it’s the same part, in the same manufacturer’s packaging, with the same warranty as one you’d pick off a dealer-counter shelf. Drag Specialties packaging is Drag Specialties packaging. V&H is V&H. Nobody’s repackaging anything in the back of a warehouse in Hull. The dealer behind the site is Harley-Davidson Leeds who trade as Iron City Motorcycles hence the Iron Stable naming.

So what’s the verdict

Honestly? The OEM diagram side is the standout, and it’s the bit we’d send people to first. If you’ve been doing this long enough that the words “compensator sprocket” and “supersession number” both ring bells, the time it’ll save you on a routine winter rebuild is the kind of thing you notice the first time and rely on every time after. The upgrade side is what every Harley parts site claims to be and most aren’t — properly broad, properly stocked, brands a BSH reader would actually order without looking them up first.

Iron Stable – Part Finder lives at /part-finder/. The full HD model index — Sportsters, Dynas, Softails, Touring, V-Rods is at /hd-models/. The brand index is at /brands/.

If you’ve been keeping an older Harley on the road in this country and you’ve not seen this yet, you’ll wonder what you were doing without it.
