Could this be the next generation of the Triumph Street Triple? Triumph may have only launched the new Street Triple range last year, which will receive at most minor changes as an update over the next few years, but Triumph is apparently already developing a new bike that has now been caught testing on the public road for the first time. Recently registered, an initial test vehicle is currently being tested in southern Europe. And there’s plenty for tech fans to discover, as the prototype has no fairing and shows some new details.
A completely new Triumph Street Triple will certainly not go into series production before the end of 2026. The color and shape of the tank indicate that the prototype uses the 15-liter tank from the current Street Triple RS. The super sports-style passenger seat will offer little comfort on long journeys. The final position of the footrests for optimum adjustment is apparently still being tested.
The prototype is equipped with Pirelli Supercorsa tires and a swingarm that bears no resemblance to the current production swingarm, but more closely resembles that of a Moto2 class racing bike. This swingarm is used to test the geometry. Because of the Moto2 swingarm, this prototype also dispenses with the low exhaust of the current Street Triple series.
The fairing brackets and tabs on the new double-braced aluminum frame indicate a fairing for the series. Behind it is the virtually unchanged 765 cc three-cylinder engine, which currently produces 128 hp in the RS version. Another new feature is the low position of the speedometer. It is positioned well below the handlebars, but directly above the headlight, indicating a sporty riding position.
If this bike isn’t the new Street Triple, but a completely new sports model with a full fairing, which is used as a small series for competition and homologation purposes, then it’s quite possible that the new frame will be stiffer to increase performance on the race track.
