2020 Triumph Bonneville Speed Twin [Model Overview]

2020 Triumph Speed Twin

2020 Triumph Bonneville Speed Twin

The 2020 Bonneville Speed Twin reintroduces to a classic name to the Triumph lineup, as the original Speed Twin ceased production in 1966. The new Speed Twin is powered by a 1200cc liquid-cooled, 270 degree crank parallel twin that produces 96 HP and 86.2 lbs-ft of torque, driving the rear wheel via a 6 speed sequential.

The Speed Twin enters 2020 as a lightweight, stripped down version of the Bonneville T120. It has removed a lot of the excess, leaving the raw DNA of the Bonneville exposed, and then clothed it in a frame and performance parts borrowed from the Thruxton. What is left is a bike that has the classic feel of a Bonneville, with the performance and agility of a Thruxston, which is a very potent mix.

Triumph themselves describe the bike as a raw experience. There are modern rider aids peppered throughout, such as a torque assist clutch, stability control, ABS, and the like, but through the rider mode settings, most of these assists can be switched fully or partially off.

The 2020 Triumph Bonneville Speed Twin starts at $12,200 US/$13,400 CDN.
