What's wrong?
The left-hand damper on the 2023 Triumph Bonneville T120 sits at the left front brake disc, the metal rotor the brake pads clamp to when you squeeze the front brake lever. The damper and its fixings, the hardware that secures the disc, help hold that disc in the correct position so braking force transfers cleanly through the wheel.
On affected motorcycles, the rubber-based damper was made outside Triumph's dimensional requirements. That incorrect size reduces the clamping load that holds the brake disc assembly tight. When the front brake is applied, the fixings are exposed to shear forces and can fracture. If that happens, the left front brake disc can loosen or detach.
Owners can notice a pulsing sensation at the front brake lever if the disc starts to loosen. A fractured fixing can make a loud bang, and a detached disc creates significant metallic noise.

What's the safety risk?
A detached left side brake disc reduces brake performance and increases crash risk. A pulsing front brake lever, a loud bang, or significant metallic noise points to a loose or detached disc. Stop riding if those signs appear and schedule the recall repair soon. Repair is free at any franchised Triumph dealer.
What should I do?
- Check your VIN to confirm your 2023 Triumph Bonneville T120 is included in this recall.

- Bring the recall notice if Triumph mailed one. If not, reference recall number 23V146 when you call.
- Call Triumph customer service at 1-678-854-2010 with questions about scheduling or dealer availability.

What happens at the repair
At the dealer, a Triumph technician installs a replacement damper and replaces the brake disc bolts covered by this recall. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through Triumph's limited warranty, not through a separate reimbursement program, because any product failure before the owner notice would have been addressed under that warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
