Much of the new Vespa GTS 310 won’t look much different at first glance, well that’s because it’s not compared to the previous model, however, one key area is very different: the completely revised engine .

Vespa claims that 70% of the new engine developed for 2025 has been redesigned, resulting in the most powerful GTS 310 ever built. A staple of previous GTS 310 models was its 278 cc liquid-cooled engine, but the upgraded powerplant has given it an improved displacement of 310 cc, while the single-cylinder stroke increases from 63 to just over 70 mm. Thanks to its modifications, the new GTS 310 produces 25 hp. Torque has also been increased, although no figures have been provided yet.
