Triumph Bonneville T120 specifications
Triumph · Cruiser
The 2025 T120 had non-cornering ABS and traction control and a conventional headlight. The 2026 bike moves to IMU-based lean-sensitive systems, which matter in a corner on a wet road and are the main reason to buy new. The engine, the 41 mm Kayaba fork and the 57.1 in wheelbase are as before.

T120 against the cruisers and the smaller Bonneville
At $13,995 the T120 costs $2,704 less than Indian's Scout Classic at $16,699 and $14,000 less than Ducati's Diavel V4 at $27,995, and it weighs 513.7 lb against the Scout's 555 lb running order. Within Triumph's own line it costs $3,000 more than the Bonneville T100 at $10,995 and $1,400 less than the Speed Twin 1200 at $15,395. The owner's note about the rear shock suggests budgeting for a suspension upgrade if you ride hard.

Indian's Scout Classic is the closest cruiser-style rival, and Ducati's Diavel V4 is far more expensive.
Triumph Bonneville T120 — specification referenceMotorcycle News says the new lean-sensitive ABS and traction control and standard cruise control may tempt existing T120 riders to upgrade, or sway the choice between a new and used bike.
Its owner section says many owners consider an aftermarket rear shock upgrade a necessity for better comfort and handling, and one owner lists the extras they paid for: heated grips, a center stand, a cockpit power outlet, a fender extender, a comfort seat, a pillion backrest and rack, LED indicators and a tank strap and bag.
Another owner says that looks aside, the Triumph is a great machine to ride, with a relaxed, natural riding position, excellent handling and brakes, and a performance-packed engine that rumbles in all the right places.

Reading the older specification and recall entries
The archived T120 specifications include 2021 and 2026 snapshots. Those dates identify the saved manufacturer pages rather than proving that every number is a change between two model years. The older snapshot lists 80 hp and the later one 79 hp; the torque descriptions are 77 ft-lb at 3,100 rpm and 77.4 lb-ft respectively.
Preserve the measurement and publication context when comparing those figures, rather than treating a small difference in published wording as evidence of an engine redesign.
The saved dimensions also move from a 31-inch seat and 57-inch wheelbase to 31.1 and 57.1 inches. These are useful reference entries for checking a used-bike advertisement, but the actual seat, suspension and tires still need inspection. An accessory saddle or altered rear shocks can affect a stationary fitting more directly than the rounding of an old catalog dimension. Use the VIN and the correct handbook when ordering parts or checking a recall.
