Summary
The Triumph Bonneville T120 has 6 recalls spanning 2016 through 2023, with the most serious being a left-side front brake disc that can loosen and detach from the wheel assembly on 2023 models, significantly reducing braking ability and raising the risk of a crash.
The 2023 model year also has a separate filing covering the same brake disc detachment concern, reinforcing that affected owners should confirm the repair has been performed. On 2022 models, alternator wiring that is not routed correctly can chafe and overheat, causing a short circuit and fire risk. This issue has a prior repair attempt that may not have fully resolved the problem, so a second dealer visit may be required for some 2022 motorcycles.
The 2016 model year has three recalls. On bikes equipped with heated grips, the right-hand throttle grip can expand when heated to the point where the throttle return spring no longer functions properly, making it difficult for the rider to reduce speed or stop. There is also a fuel pump issue where damaged wiring seal material can allow fuel to escape the tank and travel along the wiring loom to the main harness connector, creating conditions for an electrical short and fire. A separate 2016 concern involves certain aftermarket front brake levers where, at some adjustment settings, the lever blade contacts the handlebar grip and prevents the brake from reaching full stopping force.
