Overall, I like those bikes Matt, but no, their engines aren't the most "classically beautiful" engines you'll ever see sittin' in a motorcycle's frame. The R3 looks like a tractor/car motor to me, and as I've said many a time around here over the years since the T-Bird's debuted(and thus has become somewhat of a running joke around here about "Dwight and his fins"), I think the boy's in Hinckley slightly missed the boat with the T-Bird's engine aesthetics.
In my opinion they should have given the T-Bird more pronounced faux cooling fins down near the cylinder barrel area in order to not only give the appearance of what many tend to view as a more traditionally styled "Cruiser" engine(they were attempting to sway some Harley owners over to the T-Birds, ya know, and who is more "traditional" in their way of thinking about these things than Harley owners, right?!), but also because basically fins are more interesting to look at than is a slab-sided structure.
