Had a couple of people asking how to defeat the #Aprilia #RS660 kickstand to be able to eliminate the side stand on a dedicated track bike. Here is the simple logic used to test if the side stand is up or down in position. The sensor is supplied 5VDC through the orange wire and the Blue/Yellow needs to see 5VDC. The Green/White wire needs to be taken to ground via the Black and Yellow wire. Hope this helps you in your RS660 track bike builds.
