It looks to me like the changes involved a custom built subframe with lower shock mounts. I assume he fitted a Standard center stand to accommodate the higher stance, but it wasn't enough.I would be very concerned about a frame modification that changes where the pivot for the stand is. Can you please post some pics that show what he changed?
That number is 415. For originating cycle we look at the middle sequence.The 505 is stand "complete" maybe a part number associated with extra bits??...
Edit as attaced..sorry screen shot only.. std general export...
