At the heart of the 2026 Triumph Bonneville T120 motorcycle, Triumph pairs a 1200 cc engine architecture with road-focused gearing. Internal engine geometry specifies a 10:1 compression ratio.
On the scales, the Bonneville T120 measures 580 kg (1279 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 27 mm (1.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 59 mm (2.3 in) wheelbase engineered for quick, flickable steering geometry. The 3.7-liter (1 US gal) fuel tank paired with a rated consumption of 4.4 L/100 km provides an estimated theoretical range of roughly 84 km (52 miles) between fill-ups.
Within MotoLibrary's Triumph archive, this model family spans 11 indexed model years from 2016 to 2026, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
