That would depend upon which model of Suzuki Quad you meant. A Suzuki 160 quad runner will top out at around 45 mph. The Quadsport Z400 will top out at 70mph, which would not be advisable in rough terrain.
54 mph
Mine can go 45
clocked mine at 82 by god on a wheelie
About 40kmph depending on road terrain and riders weight
mine does about 65+ on the road not sure in the dirt though.
It depends on the gearing of the motor and the # of gears in the gearbox
