Increasing the motor sprocket size will create a higher gear ratio which will allow the quad to travel faster if the motor has enough power to handle the higher gear ratio. You could install a larger sprocket on the motor and test the quad to see if it goes faster to see if this method would work with the current motor.

Adding another battery and overvolting the motor to 48 Volts would increase the motor's power and RPM which would definitely make the quad go faster, however the drawback of overvolting is that the motor might run hot at the new higher Voltage which may or may not cause it to eventually burn out. Overvolting the Razor Dirt Quad to 48 Volts would require adding another battery to the battery pack (or preferably installing four new batteries), installing a 48 Volt controller - or using the existing 36 Volt controller and seeing if it can handle being overvolted, installing a throttle with 48 Volt battery level indicator if you still want the battery level indicator to function, and purchasing a 48 Volt battery charger.

Increasing the motor size and installing a larger motor sprocket and or smaller axle sprocket is the best and most reliable way to increase the Dirt Quad's top speed. A MY1020Z gear motor with a higher Watts rating than the existing motor would work as long as there is enough room to mount it on the vehicle.
