In europe (or maybe only norway) the z550ex comes with a Max speed of 40km/h from factory. That is Also the fastest I am allowed to go with the licence i have at the moment. My question is: Is there any way you kan make a button or a quick solution to switch from a 40km/h machine to a full power machine. A new ECU is a option but if I Get stopped by the police, they will easily test my machine and know that it is illegal.Can  you for example make a killswitch for the speedometer? Will a off/on switch on the speedometer make the machine not regocnize how fast it is going? Anyone have a smart solution to this?
