I don't know why, myself.
The last few times I went to a dealer, they kept trying to seat me on a GSXR or a CBR. Those are nice bikes, I'm sure, but not what I want. I have back problems, I'd not be able to stand up straight for a month if I rode one of those. Plus I can't imagine riding one across the state would be comfortable, let alone across several (like I hope to do this summer).
The local Suzuki dealer, however, -did- have a nice used 1200N Bandit. Shame I can't afford it. The local honda dealer didn't have anything in a 'Standard' other than a couple of Ninja 250s for $2500 or so. Nice little bikes, but I'm not exactly a small guy. When I asked about the 919/599, they looked at me like I'd grown a second head or something.
I wonder, whats the markup on the 'sport' bikes? I know it's fairly high on the cruisers (You can't tell me it -really- costs $20,000+ to make one), is it hte same for the sport bikes, with the standards being a lower markup item? That could explain it.
