Overview
The Triumph Bonneville Bobber is a cruiser; the profiles covered on this page are 2021 and 2026. For 2026, its 1,200 cm³ four-stroke parallel twin makes 77 hp (58 kW) and 106 Nm at 4,000 rpm, with a wet weight of 251 kg.
The 690 mm seat height makes it easier to plant a foot at a stop, while the 251 kg wet weight takes more effort to handle at walking pace. Peak torque arrives at 4,000 rpm, giving the engine useful pulling force without needing high revs; the 12 L tank makes fuel-stop planning relevant on longer rides. The rear shock has preload adjustment for adapting its setting to a load, and its 77 mm of travel leaves limited room to absorb large bumps.

Pros and cons
Advantages
Low seat
At 690 mm, the saddle can make stopping and getting both feet down easier for many riders.
ABS braking
ABS on both wheels can help prevent wheel lock during hard braking.
Adjustable rear preload
The KYB rear shock's preload adjustment lets riders adapt its setting when the load changes.
Things to consider
Small fuel tank
The 12 L capacity can mean more frequent fuel stops on longer rides.
Chain final drive
The chain needs periodic cleaning and adjustment.
Short rear suspension travel
With 77 mm of rear-wheel travel, the suspension has limited movement to absorb larger bumps.
