Harley-Davidson parts by bike

Every part on this site is checked against a bike and a year before we show it to you, which is why the first thing we ask for is what you ride. Pick it above, or start from one of the bikes below.

Why the year matters so much

Harley changes whole platforms at once, and an accessory rarely crosses the line.

• Softail and Dyna, 2018. The Dyna line ended in 2017 and the Street Bob, Fat Bob and Low Rider moved onto a new Softail frame. On the Fat Boy, only 405 of the thousand or so genuine accessories we list fit both sides of 2018.
• Sportster. The air-cooled Iron 883, Forty-Eight and 1200 Custom were last sold here as 2020 models. The Sportster S (2021 on) and Nightster (2022 on) share a name with them and almost nothing else.
• Touring. Two years matter: 2014 and 2024. On a Street Glide, year to year, 96 to 100 per cent of the genuine parts we list carry over. Across 2014, and again across 2024, it drops to 68: both years brought a new fairing and new saddlebags, so screens, lids and liners don’t swap. 2017, when the engine changed, is a smaller step at 82.

The bikes we’re asked about most

There are about 52,000 Harleys taxed in the UK and another 47,000 on SORN. These are the ones most of them are.

• Fat Boy — the most common Harley in the country, around 3,500 on the road.
• Iron 883 — more of these than any other single model, and nearly 2,000 more off the road on SORN.
• Street Bob — Dyna until 2017, Softail since; about half of UK bikes are each.
• Fat Bob — no longer sold new, so everything for it now comes from the parts book. The Dyna Fat Bob is a different bike.
• Heritage Classic — bags and screen as standard, and the older Heritage Softail Classic still outnumbers it three to one.
• Breakout — about 2,000 in the UK, split evenly between the 2013–2017 bike and the 2018-on one.
• Road King — over 2,000 on the road.
• Forty-Eight — peanut tank, fat front tyre, and close to 2,000 still taxed years after the last one was sold here.
• Street Glide — more were registered new in the UK in 2024 and 2025 than any other Harley.
• Low Rider S and Low Rider ST — same bike underneath; the ST adds the fairing and bags.
• Road Glide — numbers on UK roads have more than doubled in five years.

Genuine or aftermarket

On every category we show the genuine Harley-Davidson parts first, then the aftermarket alternatives that fit the same bike. Sometimes genuine is most of the choice. Sometimes it isn’t: for a Fat Boy we list around 90 genuine parts under handlebars and controls and more than 1,400 aftermarket ones.

Questions we get

How do I know it fits? Choose your bike and year and you only see parts matched to it. What the listing won’t always tell you is when a part needs another to go on: a detachable sissy bar needs a docking kit under it, and a rack needs an upright to hang from. Where that catches people out we say so on the bike’s own page.

My bike is laid up. Does the year still matter? More, if anything. A project bike has often had parts swapped by earlier owners, so go by the year on the V5C and check what is actually fitted before ordering.

What if Harley has discontinued the part? We leave it on the page, marked obsolete, so you can see what it was and what it was called. The aftermarket parts that fit the same bike are listed underneath it.
