As others have said, it's not a matter of need, it's a matter of want. You can be sure if they made a 2 liter bike, people would buy those too. For most, it's the desire to know they have the best and fastest. They don't want to be "lacking" in any way.
For me, it was only because the colour scheme I wanted wasn't available in a smaller displacement bike. However, I quickly realized that a liter bike is way too fast for the street, as are most 600cc sport bikes for that matter. So after a year I took it off the street and now ride it on the track only. Even so, I believe it's too fast for most tracks (except Miller and maybe TH) and a 600 or 650 twin is plenty.
Moreover, any sportbike is totally inappropriate for the street. These things were designed for the track primarily. Everything from the riding position to the suspension to the brakes were not designed for low speed comfort or handling. A powerful cruiser with plenty of low end torque like the one below is infinitely better suited for the street. It just doesn't have the nimble handling of a sportbike. But for visibility and every day handling in traffic it's ideal.
Wouldn't be caught dead on it. I have a compressed disk in my lower back. The more upright I sit on a bike, the more it hurts. That thing you posted looks like a torture rack to me. Plus, it's ugly!
I'm only 5' 6", so it's not like I'm folded up like a pretzel on my Gixxer. It's roomy as hell, I hardly have to shift at all when I
do ride around town. And I don't know what kind of brakes you have on
your bike, but I've got one-finger braking on mine, and they're not the least bit grabby, and do a great job of slowing me down, whether I'm doing 100 or 10 (yay for steel braid brake lines & sintered pads!).
However, since I pretty much loathe riding around town/commuting on a bike, I only have to deal with that crap when I head for the good stuff! :teeth
One last thing... the race
replica bikes do great at track days... but FYI- if you were going to actually
race one
competitively, there's a shit-ton of things you would need to buy, add, modify, etc. to get it race-ready. They're certainly performance machines... but they do just fine on the street, assuming the rider has sufficient skill to pilot it.
So we should all be riding cruisers? Are you serious??? I find the riding position of all cruisers horrible. And I want a bike to do what I want right NOW, not a few seconds from now when the chassis can handle it. Everybody can like their own style of bike but, to me, cruisers are low performance bikes for low performance riders. Flame on.
Well, I'll agree that cruisers are low-performance bikes... but some people really don't want a performance machine... they want something to just sit on and ride slowly from point A to point B, enjoying the scenery, and if that's what makes them happy, then more power to them. In fact, I wish there were more people who wanted bikes that like... might thin things out a bit where
I like to ride! :laughing
