Triumph Bonneville and 900 Owners Need a New Alternator Repair

If you own a Bonneville, Street Twin or Speed Twin 900 and had the alternator-wiring recall done a couple of years ago, don’t file it under “finished” just yet. Triumph has a second, newer recall for the same area of the bike, and NHTSA’s record says that bikes already repaired under the earlier recall, 24V785, still need the new remedy.

The newer campaign is NHTSA 26V078. NHTSA received it on February 11, 2026, and it covers 8,849 potentially affected motorcycles. The defect: wiring between the alternator and the main harness connector may short circuit and overheat. NHTSA’s stated consequence is an increased risk of a crash or fire.

The repair is free. What matters for you is whether your bike’s VIN is on the list, and whether the work you remember having done was the old fix or the new one.

The short version

• Who: certain 2022–2024 Bonneville T100, T120 and T120 Black models, the 2024 Bonneville T120 DGR, 2022 Street Twin, Street Scrambler and Street Twin Goldline, and 2023–2024 Speed Twin 900 and Scrambler 900 motorcycles.
• How many: 8,849 potentially affected motorcycles, per NHTSA.
• The problem: the wiring between the alternator and the main harness connector may short circuit and overheat.
• The risk: NHTSA says overheated wiring increases the risk of a crash or fire.
• The fix: a Triumph dealer replaces the current two-piece connector body with a single in-line crimped connector on each of the three alternator wires, at no charge.
• Already repaired under 24V785? You still need the new remedy.
• Contact: Triumph customer service at 1-678-854-2010. Triumph’s number for this recall is SRAN 641.

Which Triumphs are on the list

NHTSA lists 18 model and model-year combinations. Here they are by family:

Family: Model years in the recall

• Bonneville T100: 2022, 2023, 2024
• Bonneville T120: 2022, 2023, 2024
• Bonneville T120 Black: 2022, 2023, 2024
• Bonneville T120 DGR: 2024
• Speed Twin 900: 2023, 2024
• Scrambler 900: 2023, 2024
• Street Twin: 2022
• Street Twin Goldline: 2022
• Street Scrambler: 2022
• Street Scrambler “Sandstor”: 2022

One oddity: NHTSA’s database spells the last model “Street Scrambler Sandstor,” and that’s how the filing names it. If you own a Sandstorm edition, don’t rely on the spelling. Use your VIN.

A model year in the list is not the same as being in the recall. NHTSA says “certain” bikes in these groups are covered. The agency’s database repeats the 8,849 figure on every row, so it is a campaign-wide count, and you can’t add the rows to get a bigger or smaller number.

Why a second recall for the same area?

The new campaign points back to 24V785, an earlier recall. The NHTSA record is short on explanation: it says the motorcycles included in this recall that were previously repaired under 24V785 “will need to have the new remedy performed.”

The record doesn’t say what went wrong with the first remedy, how many bikes were repaired under it, or why Triumph moved to a different connector design. Treat anything beyond that as speculation. What the paperwork does establish is the practical result: a service receipt for the earlier recall isn’t proof that your bike is finished.

What the new repair does

Triumph’s remedy, as NHTSA records it, is specific. The dealer takes out the current two-piece connector body and replaces it with a single in-line crimped connector on each of the three wires coming from the alternator assembly.

That’s a connector change on three wires. NHTSA’s record does not say that the alternator, the stator or the full wiring harness is replaced, and you shouldn’t expect or ask for that. If the dealer tells you something different, it’s fair to ask them to show you the recall’s work instructions.

NHTSA says the repair is free of charge.

How to check your bike

1. Find your VIN. It’s on your registration and insurance card, and stamped on the bike itself.
2. Run it on NHTSA.gov. Triumph’s VINs became searchable there on February 18, 2026. The recall search shows open recalls by VIN.
3. Check the new campaign and your repair records. NHTSA’s VIN search shows unrepaired recalls, not recalls already repaired. Ask the dealer which work was completed under 24V785 and whether 26V078 is still open. A completed 24V785 doesn’t clear 26V078.
4. Call a Triumph dealer or Triumph customer service at 1-678-854-2010 and give them the VIN. Mention SRAN 641.
5. Ask whether the new connectors are in stock. NHTSA’s record doesn’t say how many bikes are still waiting or how quickly parts are available, so a phone call saves you a trip.

NHTSA says Triumph mailed owner letters on March 19, 2026. If you’ve moved, bought the bike used, or simply never saw a letter, you can still look up the recall yourself.

Do you have to stop riding?

NHTSA’s database flags for this campaign, “park it” and “park outside,” are both false, and the record contains no order to stop riding. That’s not the same as saying nothing is at stake. The stated consequence is a crash or fire risk, and that’s reason enough to book the repair soon rather than wait for the next scheduled service.

If you notice electrical symptoms (a battery warning, flickering lights, a burning smell, or a bike that dies while riding), don’t read the absence of a stop-riding order as permission to keep going. Those are questions for a dealer, and sooner is better. The recall paperwork doesn’t tie any specific symptom to this defect, so none of that is a diagnosis, just ordinary caution about wiring that can overheat.

If you’re buying or selling one

Recalls follow the VIN, not the owner. A few practical points for the used market:

• Ask for the paperwork. A seller who says “the alternator recall was done” might mean the old one. Ask which recall, and ask for the dealer’s invoice.
• Run the VIN yourself. NHTSA’s tool takes a minute and doesn’t depend on anyone’s memory.
• A bike from 2022–2024 may have changed owners. That’s exactly the situation in which a letter gets lost.
• If you’re selling, get the new remedy done first. It’s free, and an open recall on a bike that can overheat wiring is an easy reason for a buyer to walk away or negotiate.

What we don’t know

• Your VIN. Whether your Triumph is covered depends on the individual bike, not just the model and year.
• How many owners still need the repair. NHTSA’s record gives the potential population, not completions.
• What changed from the first fix. The agency’s text doesn’t explain why the earlier remedy was replaced.
• Parts availability and repair time. Neither is in the record.
• Whether any crashes or fires were reported. The record doesn’t say.
• Insurance. The recall paperwork says nothing about coverage or claims. If you have a policy question, such as what would happen after a fire the recall might have prevented, ask your agent or insurer.

Bottom line

If you own a 2022–2024 Bonneville, Speed Twin 900, Scrambler 900 or one of the 2022 Street models, run the VIN. If it’s on the list, call a Triumph dealer and book the free connector replacement, even if the bike already went through the earlier 24V785 fix.
