50cc motorcycles can reach top speeds of up to around 30 miles per hour with a restricted engine. That said, the exact top speed will be determined by the precise brand and model of the bike, with some 50cc motorcycles going up to 40 miles per hour.
Some 50cc motorcycle or scooter engines are restricted to limit their speed but can be bypassed by a licensed motorcycle mechanic to enhance speeds slightly. Keep in mind this won’t be a massive enhance and likely won’t exceed more than 10 miles per hour. Most states have specific laws surrounding operating a motorcycle or scooter, so make sure to check your state laws to see whether you can do this to your 50cc bike.
50cc bikes are typically smaller, lightweight choices and are great for zipping around a small town or city, where typical vehicle speeds seldom exceed 30 miles per hour. However, they may not be ideal for open roads or highways due to their limitations.
Though older 50cc motorcycles, appreciate the Honda RC116 from the 1960s, could hit top speeds of over 100 miles per hour, these types of high-speed 50cc bikes are no longer manufactured commercially, though it is possible to find some of these older vintage bikes used.
