As with all twist-and-go engines, the MP3’s 400cc single has flat and featureless power, but it picks up quickly away from traffic lights and cruises happily at 70-80mph. Flat out, you’ll just about see 100mph on the clock, which is likely to be a real 90mph. It’s never going to the thrill you, but it’s got enough power for every situation you’ll realistically put it in.
