well i have my 140cc dirt bike set up with a 49cc 4 stroke ATM, and its putting i think 50 kmp. id say with the right gear ratio you might be able to get something going 70kmp, my gearing is set for 140cc, (im only hitting low end of 3rd gear- it dosent have enough torque) but yea with the right gear set up, prob 70! GL
it goes amazingly 30 or 45
depending on the mini quad it should go to 30mph-35
50 mph if you undo the 4 flat handed screws on the engine if there isnt it means it is a lawn moer
they go about 300 km
About 30 to 35
20-30mph
10-15 mph
30 to 45 mph
Approx. 35 mph
a 125cc varies between 65-85mph with a four stroke engine, and 65-up to 100mph with a two stroke
it depends on how high a cliff you throw it off of.
id say about 25 mph at the most
