it goes as slow as a turtle since he has a ttr 125 xr80 and and he wants a 250ex
70ish
About 95 kph give or take
about 120 mph I disagree with ^ above, a 200cc chopper only goes as fast as the displacement it can average between 65mph and 90mph depending on where it is set at, however a 200cc motorbike could possibly go 120mph with the proper displacement.
about 160-180mph
170
200cc four stroke single engined karts have a top speed mine went at top speed of 55 mph RK 200cc 56WS Atv 200cc two strokes or twin-engined four strokes will be considerably faster so it depends what sort of kart you mean.
50 mph and over
I's nearly about 35 kph is the only seed which 4 stage mini moto can go.
It can go up to 125 km/h.
about 60-75 mph depends on the company and how the gears are set my friend ran nitro and got 50 horse power and 125 mph on 200cc atv i lied my Roketa RK 200cc 56WS Atv can Go top speed of 60 Mph on 16.3 Horsepower motor 197cc displacement but that is very fast so i love it my friend blowed up his on nitro
it goes amazingly 30 or 45
347km per hour
