Our newest kart is a Zanardi chassis in combination with a Rotax engine.
Capable of doing speeds above 125km/h without the need to shift gears.
For laptime measurements and to keep track of temperatures and rpm it's fitted with an Alfano data transfering device.
Time measuring is done by a magnetic sensor fitted to the kart and several magnetic strips inbedded in the circuit.
Temperature readings or done by a series of sensors.
