A kawasaki Kx 100 will go top speed at about 68-70 Miles per hour it is a 30 hp machine, and is loads of fun. I own one. :) I suggest you buy one. It' is a great starter bike!
around 65mph
My 2012 125 does about 80
about 50mph that will be pushing it. I rode one and it was fun it is a good starter bike :)
30 mph - 40 mph
With stock gearing top speed would be 52-55 mph.
i clocked my racing kx100 with stock gearing going 65 guned
not that fast
Not as fast as i am!
Ive read about 62-63. Thats all stock. However off road thats haulin. I have a kx100 and it goes as fast as youll want to off road. If your not sitting all the way forward it will pop a wheelie when it hits powerband in second. I can only ride at off road riding areas so I havent hit top speed. Im 5 foot 6 inches and I love my kx100. Its the biggest bike I can get my leg over comfortably. I would totally recommend it. Just remember to keep a plug wrench handy since its a 2 stroke.
