The Tweet is powered by an air-cooled 125cc engine that makes 8.5bhp – fairly modest for a 125. But it makes up for it with low weight – it’s only 106kg, which is much lighter than a lot of 125cc scooters and even on par with some 50cc scoots. As a result it feels fairly nippy, even compared to Peugeot’s own 12.5bhp LXR125.
