TRIUMPH Street Twin Models/Series Timeline, Specifications & Photos

The Triumph Street Twin was a naked classic motorcycle presented by Triumph Motorcycles in 2015 and released in 2016 after four years of development. The bike was assembled at Chonburi in Thailand and was the successor to the Bonneville SE.

The Street Twin was powered by a 900cc engine with a multipoint injection system controlled by a ride-by-wire system, which was the first for Triumph on the Bonneville series. In addition, the bike was fitted with traction control and an anti-hopping clutch.

In 2019, the British motorcycle manufacturer launched the Triumph Street Twin, a classic naked machine with modern technology. The bike was the best-selling modern classic, with more than 90 percent of the Street Twin sold fitted by the customers with Triumph accessories.

The bike underwent several upgrades, including new Brembo front calipers, a higher specification front fork, improved ergonomics, and enhanced rider and passenger seat comfort.

In the technology department, the 2019 machine packed new Road and Rain riding modes, an optional Tire Pressure Monitoring System (TPMS), ABS, switchable traction control, an LED rear light, an immobilizer, and a USB power socket.

In the performance department, the 2019 Triumph Street Twin had installed in plain sight underneath its fuel tank a 900cc four-stroke parallel-twin liquid-cooled engine fed by a fuel injection system, delivering an output power of 65 hp with peak force at 7,500 rpm and 80 Nm (59 lb-ft) torque at 3,800 rpm.
