Every customer asks the same question in their first month of vintage Triumph ownership: where do I buy stuff? Here is the honest version, sorted by what you need most often.

Tier one: the suppliers we use

British Cycle Supply in Nova Scotia. Broad catalog, knowledgeable support, fair pricing. Their phone help is the best in North America for a quick "is this the right part for my year" question.

Burton Bike Bits in the UK. The deepest single catalog for Triumph parts on the planet. Fast shipping to the US even with the post-Brexit customs. No nonsense. We order from them weekly.

LF Harris in the UK. Factory-spec reproduction for many engine internals. Their pistons and bearings are the closest you will get to OEM quality without paying NOS prices. Worth the premium on rebuild parts.

Klemp Parts in Germany. Specialist in early Triumph (pre-unit specifically) and the hard-to-find bits — magneto parts, early gearbox internals, period-correct fasteners. Slower shipping, worth the wait when you need what they have.

Le Hangar 23 parts catalog. Yes, this is a plug, and we will be honest about its limits. We stock the service-tier parts we use on the bikes we sell — gaskets, cables, common consumables, and a curated set of upgrade items. We are not trying to be Burton or LF Harris. For everyday service items where the seller relationship matters, we are a good place to start.

Tier two: specialty and one-bike-only

Trick Triumph in the US. Cylinder studs, cam followers, performance parts. Their stud kits are the right answer when you are pulling a head that has been over-torqued.

Surrey Cycle Works in the UK. Amal carb slide re-sleeving with stainless inserts. About £200 per carb shipped. Worth it on a worn carb body where new bodies cost most of the same money.

Triple Cycle in the US. Bottom-end performance specialists, mostly aimed at racing builds. Useful for the rebuild that is going beyond stock.

eBay UK. Legitimate NOS parts and occasional fakes. Pay attention to seller history, location, and feedback. NOS Lucas electrics and original Amal carb bodies show up here and are sometimes the right answer.

Where to be careful

Random eBay China carbs claiming to be Amal Mk1 replicas. They fit physically. They run poorly. The slide tolerances are wrong, the jet sizes are not consistent across "identical" units, and the gaskets fail in a season. We have rebuilt enough of these for customers to recommend against them universally.

Cheap aftermarket forks and shocks. Ride a customer’s bike with bargain shocks once and you will never buy them. The damping is wrong, the springs are wrong, the bike handles worse than the worn-out original units they replaced.

Generic British-bike "fits all" levers and cables. Most are not actually the right pull, pivot, or thread. They mount and they look fine and the clutch feels strange. The right cable for your bike is sold by the suppliers above, by part number.

Parts where you pay up

  • Carb slides. Surrey Cycle Works re-sleeves are the right answer on worn carbs. NOS Amal slides if you can find them.
  • Cylinder studs. Trick Triumph or original Triumph spec. Generic UNF studs of the wrong heat treatment will pull threads.
  • Gaskets. LF Harris copper-faced for rocker boxes. Cometic for any specialty application. Cheap paper gaskets in random thicknesses fail at the wrong moment.
  • Pistons. JCC, factory NOS, or LF Harris. A no-name piston on a 60-year-old engine is gambling with your build.
  • Wheel rims. Akront, Excel, Sun. Generic Indian-market rims do not run true and the spoke nipples corrode.

Parts where standard repro is fine

  • Most chrome trim — tank knee pads, side covers, badges.
  • Cables (Barnett are perfectly good and less expensive than original Lucas).
  • Most fasteners. Whitworth and UNF spec, easy to source, no real difference between OEM and aftermarket as long as the spec is right.
  • Fenders, both steel and plastic. The repro market is mature.
  • Most rubber bits — handlebar grips, foot peg rubbers, rear damper bushes.

Parts that are surprisingly hard in 2026

Six-volt dynamo brushes and field coils. The supply has thinned out. Buy from Burton or British Cycle Supply when you see them in stock.

Magneto specifics on pre-units. The Lucas K2F and K1F mags are findable but the internals — points, coils, the magnet assembly itself — are getting harder. Pierce Vintage in the UK specializes here.

Original "Made in England" Triumph mufflers. Good repros exist (Wassell, Armours). The truly correct OE-spec mufflers for some specific years are no longer in production and only show up used.

Buy good once. Buy junk three times.

The relationship

Build a relationship with one or two suppliers. Tell them what bike you have, what year, what you are working on. They will start to know your bike and what you actually need. The shipping math works out better when you place fewer, larger orders, and you avoid the "this part is wrong for your year" surprise that comes from buying off catalog listings alone.
