About this model
About the Triumph Bonneville T 120
The Triumph Bonneville T120 is one of the most iconic British motorcycles ever built. The original debuted in 1959 as a 649cc parallel twin named after the Bonneville Salt Flats land speed record. Through the 1960s and 1970s the T120 became the symbol of the British motorcycle industry: fast, stylish, and ridden around the world. Classic production ran until 1988. In 2016, Triumph introduced a modern reinterpretation carrying the same name but with a 1200cc water-cooled engine and contemporary electronics.
The classic T120 draws collectors and enthusiasts of British motorcycle culture. The riding position is upright and comfortable, the engine smooth and characterful. Maintaining the classic requires knowledge of vintage British engineering (Lucas electrics, Amal carburettors). The modern T120 targets riders who want the classic appearance with contemporary reliability. Classic competitors: Norton Commando, BSA A65. Modern competitors: Royal Enfield Interceptor, Honda CB1100.

Before you buy
What to check before buying
- Check the Lucas electrical system for wiring condition and dynamo output; classic T120 electrics are notoriously unreliable and require regular attention.
- Inspect Amal carburettors for wear and hardened rubbers; degraded diaphragms and dirty carbs are the most common cause of running problems.
- Look for oil leaks at engine case and cylinder head gaskets; classic T120 engines commonly seep at aged seals.
- Ask about frame condition around the main tube; older bikes with heavy use or accident history sometimes show cracks in the frame tubes.
