Seems like it's an American thing. I drive a super-charged 4 cylinder car. It's plenty fast, get's great mileage and handles well. But, when I put my family in the car, or three co-workers, turn on the A/C, and try to pass going up hill, it's just not there.
Same with the 790cc. Modify for an extra three or four horses, even 10! Most of us would do better to drop 15 lbs ourselves to increase the perfomance of our bikes. I'm pushing 220 lbs, when I put my wife on the back (who god love her is the same size as when I married her!) the TBA has to do a lot of down-shifting to make it up some mountain passes.
Running a 1300cc doesn't generally have that problem. And by the same token, you can tow a big boat with a four cylinder pick-up. But how long with the transmission, engine, etc last compared to a V8?
I love my bike, but I for one would love it more with an extra 500cc's.
