Although it’s a buzzy little beastie UK law restricts 50cc moped users to a measly 30mph. However, it’s possible to get over 50mph from the two-stroke Sherco just by swapping the exhaust for a race-spec item. Further tuning requires a bigger carb and, of course, the trade off is greatly reduced reliability. The bore is Nikasil plated for better efficiency, but that makes it more expensive to replace as you can’t re-bore it.
