I agree, for the most part. I no longer ride my Aprilia Mille R on the street, and that is a bike that was consistently lauded as a great bike to ride on the street. Sure, it is 'comfortable,' I even managed a 10,000 mile, 8 week tour on it, but that was hardly its design brief. I also managed, by virtue of being single and well paid in the high tech industry, to do about 20 track days last year, and by the end of that season, there was little doubt that the Mille has no place on the street. Since I just couldn't bring myself to ride it like it needs to be ridden on the street after spending so much time knee-down at the track, I retired the bike to track only use, which kills me, as I have invested a ton of time and money in making that bike ride the way I want it to. The acquisition of a fiancee really hastened the process, as we clearly needed a motorcycle that we can both ride together COMFORTABLY, since we try not to use the truck (a total beater, I might add) for anything but hauling the bike to track days.
I bought a BMW K1200RS, which, while not the fastest, or best handling sport touring bike out there, does come with ABS brakes, standard cruise control, climate control (adjustable windshield), great luggage, and comfy pillion accomodations. With some work, I can keep up with the knee draggers on the local moto-roads, and the bike is perfect for 2-up weekends out of town. The ABS brakes have already saved our bacon, when an old lady turned left across 3 lanes of traffic into a driveway without looking or signalling. We hit her, but just barely, and I was able to slither the bike around the front of her car while under hard braking, doing minor cosmetic damage but nothing severe and both myself and my fiancee were effectively untouched (but a little shaken).
BMW seems to be the only manufacturer really pushing the limits of street rideability, with the other sport touring models from other manufacturers merely following their lead, occasionally making minor improvements of their own along the way. BMW is not a perfect company, and you certainly pay a premium for the bikes (resale isn't great, however, check out the used market. Most Beamer owners are fanatical about maintenance and the bikes are nearly bulletproof over the long haul), but I think you get a supremely ridable motorcycle.
They aren't for everyone, though. If I could only afford a single bike, I doubt it would be a BMW. Many of the 'ridable' japanese models have a more compromised touring capability in favour or more sporting personality, and if I didn't have the dedicated track bike, I am sure I would riding one of them. Then there are the pricey, but very effective Italian sport tourers. Those would be great occasional track bikes if you don't spend a lot of time with a pillion on the back.
However, many (most?) riders are greatly affected by what they read in the moto-press. As long as the magazines (this one included) continue to denigrate everything but the latest race reps as 2nd class, 'old man' bikes, the 18-30 crowd just aren't going to buy them in the quantity that they should, and we will continue to see large numbers of accidents, injuries, and fatalities as people attempt to ride those bikes somewhere close to the level for which they were designed on public roads.
Either that, or we need a chain of motorsport parks around the country which provide track access without the expense of a full track day. Something along the lines of the Nurburgring's pay per session model, which would allow an economically disadvantaged rider to show up for 2 or 3 20 minute sessions after work on a Wednesday or Saturday morning, or such. I don't know how you could do such a thing from a liability and profitability standpoint, however. Maybe run car and motorcycle track schools on weekdays, with open track sessions after 4pm every afternoon, alternating car and motorcycle days. I'd be so broke if I lived within an hour or two of such a place. Especially if they had mechanics on site and tire changing facilities. That's my dream.
