I'm having a hell of a time figuring out what my bikes corresponding vin number is for my '15 STR. I purchased the digital service manual from haynes and none of the vin# options it gives to figure out which of the sections I am supposed to look at for instruction match up with my bikes vin...(yes it is for the correct year/model) Also any time on a site trying to look up parts based on my model they give me the compatibility options based on vin and they are always the same #s begging with a 5 e.g. "560476" and there isn't a 5 anywhere in my vin#. What am I missing? Thanks!
