2020 Triumph Bonneville Street Twin
The 2020 Bonneville Street Twin is an evolution of a model that has been one of Triumph’s best-sellers for many years now. The new specifications for the Street Twin give the 900cc engine 10 more HP, now at 65 HP, and has increased the torque to 60 lbs-ft from 55.
The evolution also sees a new ride-by-wire throttle, selectable rider modes, ABS, switchable traction control, and a new version of the torque assist clutch to reduce lever effort. LED lights front and back are also now standard. As well, a TPMS system is now available as an option, to warn you of any slow or fast punctures to either front or rear tire.
The evolution of the Street Twin’s engine has also increased its durability, as the dealer recommended service interval is up to 10,000 miles from the previously recommended 8,000.
