Will we be seeing the next generation of the Triumph Street Triple? Triumph may have released the new Street Triple range just last year, which will receive at most minor updates over the next few years, but Triumph is apparently already developing a new bike that has now been spotted testing on public roads for the first time. Recently registered, an initial test vehicle is currently being tested in southern Europe. And there is 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 of the current Street Triple RS. The super-sporty style passenger seat will offer little comfort on long trips. The final position of the footrests for an optimal fit appears to still be under testing.
The prototype is equipped with Pirelli Supercorsa tires and a swingarm that bears no resemblance to the current production swingarm, but rather resembles that of a Moto2 competition bike. This swingarm is used to test the geometry. Due to the Moto2 swingarm, this prototype also does away with the low exhaust of the current Street Triple series.
The supports and fairing brackets on the new double-beam aluminum frame indicate a fairing for the series. Behind them is the 765 cc three-cylinder engine, virtually unchanged, which currently delivers 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 is not the new Street Triple, but a completely new sports model with full fairing, which is used as a small series for competition and homologation purposes, then it is quite possible that the new frame will be stiffer to increase performance on the race track.
