There may be something else going on. I've heard rumblings that the new generation doesn't ride like we do. They're not into motorcycles or cars for that matter. They have their iPods and whatever...the average age for first time road licenses I think is rising.
Since when has BMW marketed to the younglings with their premium prices?
I've been accused of being an old soul at 24. I like computers and I like motor vehicles, and I like them
separate! FWIW, I seem to notice a lot of folks my age go out and buy a sport bike, ride it a little bit, and then when it breaks down they sell it and are done. Even the fancy new bikes still need maintenance, especially when they sit eight months out of the year. I know just about nobody my age who can turn a wrench.
Also, a lot more riders on the road now are over the hill, and the average age of motorcyclists in crashes has gone up too. I think the mid-life-crisis-buy-a-hardley crowd has something to do with it, and I also think my generation sees motorcycles more as an image thing now than a transportation thing.
