Yeah, this is the issue. It's visual and also practical too - it makes it harder to get a figure to sit in the proper way.
Yeah, it is the best 12" Hasbro piece by a long shot. It's kind of remarkable given you could get it for well under $50 - it was on clearance a lot back then.
Yeah, the SSC Scout is a bit big, like most of the newer SSC troopers - ATAT driver, TIE. They really have to be lowered to bring their helmets into correct proportion. I did that with my TIE, but felt the Scout and ATAT just had too many inaccuracies so sold it. The V2 Scout has much better apps, but still has a bit of a wonky sculpt to my eye.
Someone earlier mentioned by modded Hasbro bike so I'll post the pics again (as I mentioned when I posted these before, the scout was deliberatly built to be about 12 1/2" tall, to match the slight overscale of the bike, though this displays fine next to other 1/6 figs with the overscale not noticeable for some reason):
