That ad says made to order. I bet you could get a straight down tube and iy also looks like there are lugs for a hinged seat on springs so the seating doesn't seem too low to me. But then again no such thing as too low on a hardtail chopper to me. This makes like 3 or 4 guys I see making hardtails for the new twin. Powder coat and engine mounts are extra it says too so depending how much extra seems a bit steep of a price to me when I could go buy a basic black T-100 for slightly more.

I learned all I need to know about life by killing smart people and eating their brains.
