Any idea what this is?

Within the delivery pack, there is a bag of bolts and washers etc, bit in particular there is the item below, any idea what it is?

sidestand disconnect kit?

Yep, I think its the switch that fools the ECU into thinking the sidestand is still there, when its removed for racing.

The rubber bits and bolts in the bag are apparently used to raise the seat a little, though I haven't used them myself, and I'm not sure what the advantage would be...
