I agree with you, but... Have you ridden a new 600 vs new 1000? For example a zx6r and a zx10r... there is no difference between them except hp. Weight and handling of late model liter bikes is amazing. The h2 is a show pony and technology experiment for sure, but Im pretty sure any reputable rider will say if you actually want to be fast, buy a zx10r instead... or R1 or gsxr1k or panagale or s1000rr or whatever.
I've ridden a long list of bikes and traded with friends for an hour or so here and there. A new 600 might have the same horsepower as a 1990s 1000, but it doesn't compare to the power and torque of a new 1000. You just don't get the same straight line pull for passing maneuvers and most of the inline fours you have to be high in the powerband. Even comparing a new 675 to my old 955i Speed Triple is no comparison. The low end torque at low RPMs destroys the 675. I can pop up wheelies on the triple at like 3500rpm in first. Gotta be up around 6k on the 675. The major difference is weight and handling.
As far as 'going fast' goes, if you're talking about track riding, many 1000+cc motorcycles aren't great on really tight tracks. Might be great on gigantic Laguna Seca, but Eagles Canyon in TX would be better with a supermoto or 600. If you're talking about a straight line, it's all about peak power and the H2 has that in gobs. An older Hayabusa could easily obliterate it on a stright for much cheaper, though. Just look at Ghost Rider's 500hp busa streetfighter...
I don't think I'll ever buy a 600 unless it has boost to put it close to the power levels I'm used to. I like to be lazy on the throttle and pull hard in 6th from 3,000 RPM. You're not going to get that with any modern 600 without going to a pizza-sized rear sprocket, which murders your top speed. That said, I see no need for H2 power. I've ridden a Panigale R. It's a hilarious riding experience, but it's also a bear for the average rider to control as a daily driver. Hell, my Diavel will very quickly get you dead if you're not on your game every time you throw your leg over, and it's down almost 100hp from the H2...
When the 1098 first came out, there were at least three wrecked on the Deal's Gap Dragon the first month of summer. I bet the same happens with the H2 as well-to-do squids take delivery and get in over their heads.
