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.
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.
25-27-mph standard top speed for a mini dirt bike
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"
