Triumph Bonneville: generations, versions and what to check when buying used
The Triumph Bonneville is one of Britain's longest-running motorcycles: the first appeared in 1959, and the modern line has been in production since 2001. We look at the modern generations, versions and what to check when buying used.
Bonneville in brief
The Bonneville is a classic British motorcycle with a twin-cylinder parallel-twin engine and retro design. The modern line includes the T100, T120, Bobber, Speedmaster, Thruxton and Scrambler variants, all sharing the same platform but with different details.
The most popular used models are the air-cooled Bonnevilles from 2001–2015 and the liquid-cooled T100 and T120 models produced from 2016 onwards. Each generation has its own advantages: the earlier ones are simpler and more affordable, while the later ones are more modern and powerful.
Generations — what's the difference
The first modern generation (2001–2015) featured an air-cooled parallel-twin engine, initially around 790 cc, then around 865 cc from 2007, later with fuel injection (the bodies mimic carburetors). It's straightforward, long-lasting technology.
The second generation (from 2016) got a liquid-cooled engine: the T100 with 900 cc (around 65 hp) and the T120 with 1200 cc (around 80 hp), plus more electronics — ABS, traction control and riding modes. These motorcycles are better suited to daily use and touring.
Engine and transmission
The second-gen T100 engine is 900 cm³, around 65 hp, while the T120 is 1200 cm³, around 80 hp, with a significantly higher torque. Both offer smooth, classically balanced performance.
The gearbox is manual (5 or 6 speeds, depending on the model), and the drive is via chain. Newer models come with ABS and traction control, while higher-spec versions add cruise control and multiple riding modes.
What to check when buying a used Bonneville
Inspect chromed and painted parts for corrosion or fading, check the exhaust pipes and shock absorbers. Classic-styled motorcycles were often modified — ask about any changes made and if original parts are used.
Check the chain, brakes, tyres, and coolant (in newer versions). The engine should run smoothly, without unusual noise, and the electrical system should be fault-free. Refer to the service manual for the service schedule.
