Vintage Triumph Decals & Transfers

Triumph Decals Triumph decal Triumph Stickers

Shop reproduction decals for Triumph 500, 650 and 750 twins. They cover the tank and side panels, oil tank, air cleaner, seat and instrument panel. Most designs come in two forms:

  • Water-slide transfers: these have part numbers starting TBS-S. They’re the thin, original-looking choice, and you can clear-coat over them.
  • Peel-and-stick: these have part numbers starting TBS-P. They’re quicker to apply but more visible on the paint.

Where the original Triumph part number is known (60-xxxx), it’s in the product title. See the application guide below the grid, and our step-by-step water-slide guide.

What Makes Vintage Triumph Decals Different

Badges on the tank, decals almost everywhere else

  • Tanks: Meriden-era tanks mostly carried chrome badges rather than decals. There was the “mouth organ” from about 1957 to 1965, then the “eyebrow” for 1966–67, then the “picture frame” from the late 1960s to 1979. Decals returned to some 1979–83 models (Run Motor Run – Triumph logo history). Shop tank badges and Triumph tank parts.
  • Elsewhere: decals named the model on side panels (toolboxes), oil tanks, air cleaners, seat pans and instrument panels.

Many decals did a job

Several Triumph decals are instructions or warnings, not decoration:

The electrical decals warn about polarity

Triumphs were positive earth until 1979, when the T140 switched to negative earth (webBikeWorld). The under-seat warning decal tells anyone connecting a battery or charger which terminal goes to the frame:

Fit the one that matches how the bike is wired now, and see Triumph electrical for polarity-sensitive parts.

The speed-record decal tells the Bonneville story

On September 6, 1956, Johnny Allen rode the Texas Cee-gar streamliner, powered by a 650 Triumph Thunderbird engine, to 214.17 mph on the Bonneville Salt Flats (Cycle News). The FIM refused to ratify the record in 1957 because the timing gear lacked its seal of approval (AMCN). Triumph still advertised the record, and the “World Motorcycle Speed Record Holder” decal comes from that (AMA Hall of Fame – Johnny Allen). It’s available as a water-slide, as a peel-and-stick, and in black for the 6T Thunderbird.

How to Apply Triumph Decals Without Problems

Read our Tech Blog: Application Techniques for Waterslide Decals

Preparation (both types)

  1. Let fresh paint cure. Classic Transfers suggests leaving new paint about a week, because transfers applied too soon can bubble (Classic Transfers).
  2. Clean the surface. Remove wax, polish, oil and dust. Wipe with a tack cloth just before applying. A speck of dust under a sticker leaves a permanent “pimple” (our water-slide guide).
  3. Mark the position. Use small pieces of masking tape as guide marks. Take position from the parts book, a factory photo, or the matching panel on the other side.
  4. Work at room temperature. Most vinyl makers specify roughly 50–90°F for both the air and the surface (FASTSIGNS vinyl care sheet (PDF)). Water-slide decals also behave best at room temperature.
  5. Rehearse first. If you’ve never applied a water-slide decal, practice on a spare decal or the scrap border of a sheet.

Applying a water-slide decal (TBS-S)

  1. Trim. Cut close to the artwork to minimize visible clear film, especially if you won’t clear-coat (our guide).
  2. Soak briefly. Dip it in lukewarm water for about 5–10 seconds, or lay it on a wet cloth and mist the top (our guide). Don’t use hot water, and don’t leave it submerged for more than a minute, or the film can separate and tear (Kadee decal instructions (PDF)).
  3. Slide, don’t lift. Hold the decal against the panel and slide the backing paper out from under it. Lifting the film off by itself folds and tears it.
  4. Float it into place. Keep the panel wet so the decal can be nudged into position. If it starts to stick, add water at the edge.
  5. Push out water and air. Work from the center outward with a soft cloth or rubber squeegee, then blot (Phoxy Design). A stubborn bubble can be eased with very gentle warmth from a hair dryer (our guide).
  6. Curved surfaces. A decal setting solution such as Micro Set improves adhesion and helps the film conform (Microscale (PDF)). Test it on a spare piece first, because softeners can wrinkle some films.
  7. Dry fully. Leave it overnight, and allow at least 24 hours before clear-coating (Classic Transfers).

Clear-coating over a water-slide decal

  • Compatible clears: two-pack (2K) lacquer and clear oil-based varnish both work over water-slide and vinyl transfers.
  • Clears to avoid: clear cellulose and single-pack acrylic sprays can make transfers shrink.
  • How to spray: start with light mist coats, then build to full coats (Classic Transfers; Rothko and Frost).
  • Test first: always test your clear on a spare decal.
  • Petrol resistance: oil-based varnish can take one to two weeks to cure before it resists petrol (Classic Transfers). For anything near the filler cap, use a fuel-resistant 2K clear.

Applying a peel-and-stick decal (TBS-P)

  1. Clean. Wipe with isopropyl alcohol, not an ammonia glass cleaner, and let it dry.
  2. Position. Peel back a corner or one edge of the backing, line it up with your tape marks, and stick that edge first.
  3. Smooth. Peel the rest of the backing away gradually while smoothing from the stuck edge outward with a soft squeegee or a cloth-wrapped card.
  4. Wet application. Spraying the panel with water and a drop of dish soap lets vinyl slide into position before it grabs (FASTSIGNS (PDF)). But 3M advises using the wet method only when the film maker recommends it (3M Instruction Bulletin (PDF)). Try it on a spare first.
  5. Edges. Press the edges down firmly. Don’t wash the bike or let fuel near it for a day or two.

Vintage Triumph Decals FAQs

What’s the difference between water-slide and peel-and-stick Triumph decals?

A water-slide decal is a very thin film that releases from its paper in water and is slid into place. It looks painted on and is meant to be clear-coated. A peel-and-stick decal has its own adhesive, is quicker to apply, and is thicker, with a more visible edge. Our water-slide part numbers start TBS-S, and peel-and-stick part numbers start TBS-P.

Which type is more original-looking?

Water-slide, especially when clear-coated, because the film nearly disappears into the paint. For concours restorations it’s the usual choice.

Do I have to clear-coat water-slide decals?

It’s strongly recommended. Uncoated water-slide film is fragile, and fuel or polish can damage it. Clear coat also hides the film’s edge.

What clear coat can I use over decals?

Two-pack (2K) lacquer or clear oil-based varnish. Avoid clear cellulose and single-pack acrylic sprays, which can make transfers shrink. Wait at least 24 hours after applying, start with mist coats, and test on a spare decal.

How long should I soak a water-slide decal?

About 5–10 seconds in lukewarm water, or until the film just starts to slide. Too long, and the film can separate and tear. Never use hot water.

Why did my decal wrinkle, tear or go cloudy?

Wrinkles usually mean it was moved after it started to set. Tears mean it was lifted rather than slid, or soaked too long. Cloudiness (silvering) is air trapped under the film or a dull surface. Apply to smooth, cured gloss paint and squeegee from the center.

Can I apply decals to freshly painted parts?

Let the paint cure fully first, about a week for most paints. Transfers applied too soon can bubble.

How do I get a peel-and-stick decal straight?

Mark the position with masking tape, stick one edge first, then peel the backing away while smoothing outward. Some vinyls can be applied wet with soapy water so they can be adjusted, but test first.

Are these decals petrol-proof?

Not on their own. On or near the tank, cover them with a fuel-resistant 2K clear coat. Oil-based varnish can take one to two weeks to become petrol-resistant.

Which Triumphs had decals on the tank?

Most Meriden twins used chrome tank badges, with decals on side panels, oil tanks and air cleaners. Some models, including certain US-market and later 1979–83 bikes, carried tank decals. Check the parts book for your model and year.

What does the Positive Earth or Negative Earth decal mean?

It warns that the frame connects to that battery terminal. Triumphs were positive earth until 1979 and negative earth after. Fit the decal that matches how the bike is wired now.

What is the World Motorcycle Speed Record Holder decal?

It celebrates Johnny Allen’s 214 mph run at Bonneville in September 1956, in a streamliner powered by a 650 Triumph Thunderbird engine. The record inspired the Bonneville name and appeared in Triumph’s advertising.
