Depends on what are you running the 49cc engine on. But for a scooter, not pocket bike, on a flat road 70km/hr at max. You need to make your body flat also to cut the air. Otherwise about 65km/hr standing up
This is from all stock engine and scooter.
If downhill 75km/hr and doesn't go more at all.
If you tune it up, i think you can reach 90km/hr to 110km/hr easily depending on the tune up level but the engine life will be short and you will need to spend so much money for little performance.
The stock engine on a Honda City Express moped is 49cc. Speed can be increased by using high grade gasoline.
25-27-mph standard top speed for a mini dirt bike
Yes, the Ruckus needs a class M license, aka Motorcycle license. New York looks at Top Speed AND engine size. The 49cc engine is fine, but the top speed disqualifies the Ruckus as a class B moped (Limited use Motorcycle). The top speed puts the Ruckus at the low end of Class A --- Full Motorcycle; and Full License.
it is 60 kilometer's per hour
you do not need to register a 49cc moped/scooter but you do need a car license to ride one. you are not allowed on turnpikes or highways and the top speed can not exceed 30mph.
Depends what engine. 25hp engine top speed 100km/h. 36hp engine top speed 115-120km/h, 42hp engine top speed 132km/h, 50hp top speed 140km/h. Last but not "least" 60hp top speed 155km/h. Get more info at "The Samba.com"

A 49cc motor, typically found in scooters or small motorcycles, can reach speeds of around 30 to 40 mph when unrestricted. The governor is designed to limit the engine's speed for safety and regulatory compliance; removing it can increase the top speed. However, actual speed may vary based on factors such as the weight of the rider, terrain, and overall condition of the vehicle. Always prioritize safety and adhere to local regulations when modifying engines.
