The EVPT stand is a Harley shop tool that is used on a Fat Jack, to provide a level jacking surface at the jacking points. It is a plate and standoff pins, that provide a stable flat jacking surface.
Having just lifted the bike with a Fat Jack without the plate, I won't do that again without the tool or something that approximates it. The belly is too narrow and rounded to be stable on a jack alone.
Oh, the HD EVPT stand is a shop tool that is pricey and not generally available to end users. So, I'll prob be using track stands or improvising to lift the bike.
