depends on the transmission, aerodynamics, tires, tire contact surface, limiters of any kind, and many others so the real question is is it stock?
65-80mph depending on gearing
go with the four stroke less mantainice = cheper in the long run
a 125cc varies between 65-85mph with a four stroke engine, and 65-up to 100mph with a two stroke
Approx. 65 to 75km/h will be the max speed.
No such thing as a 5-stroke dirtbike.
it will go 650 mphs
With bands they can go 80
85
I can't find any mentions for a Suzuki DR-Z 125 2-stroke. The Suzuki DR-Z 125 4-stroke bike has a top speed of 50mph
They can go pretty fast for a 4 stroke of that size. My one goes around 60 or 70.
It will go about 45-50 mph
About 60 to 62 mph
