Im not sure either but i kno my dad took something off of mine and made it go atleast 40.
Up to 30 to 35 Mph.
75 mph
the AVERAGE speed of a thunderstorm is 30-35 mph. But some tend to go overboard and go 60 mph
about 271-290 mph
The way you calculate mach into mph, is you type it into the calculator and it will tell you the answer! Now go do it....
My 2004 kx 85 tapped out sixth gear at 68 MPH
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.
about 160-180mph
50 mph
2000 mph
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 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
30 MPH
40-50 mph
a gear-box kart i think it can do about a 150 mph depending on how you gear it
i think it goes around 50-70 mph but i may be wrong
The record for a R 1 powered Go Kart is 154 MPH on the Mojave Mile October 2011 event
it ranges from 40 to 50 mph depending on weather conditions size of go kart size of rider and terrain your riding on
