Overview
The Triumph Bonneville T120 is a naked motorcycle; this page covers its 2021 model-year profile. Its liquid-cooled, 1,200 cm³ parallel twin makes 79 hp (59 kW) at 6,550 rpm and 105 Nm at 3,500 rpm, with a wet weight of 235.9 kg.
Peak torque arrives at 3,500 rpm, giving the engine strong pulling force without needing high revs. The 790 mm seat height can help riders with shorter inseams get their feet down, while the 235.9 kg wet weight will be noticeable when maneuvering slowly. Fuel consumption is 4.5 L/100 km, and the 14.5 L tank gives a calculated range of about 322 km. ABS is fitted to both disc brakes; the rear suspension has preload adjustment, and both ends have 120 mm of wheel travel.

Pros and cons
Advantages
Strong low-rpm torque
With 105 Nm available at 3,500 rpm, the engine delivers its peak pulling force at relatively low revs.
ABS on both brakes
ABS-equipped disc brakes at the front and rear help control wheel lockup during hard braking.
Rear preload adjustment
Adjustable rear-suspension preload lets the rider adapt the setup to changing loads.
Things to consider
Weight at low speed
At 235.9 kg wet, the motorcycle takes more effort to maneuver when moving slowly or pushing it around.
Chain final drive
The chain needs periodic cleaning, lubrication, and adjustment.
