The difference to me, is that traction is way more important on a sportbike, when you are leaned way over dragging the pegs in turns. Most cruisers/touring bikes are not ridden that way, they spend most of their time straight up, or barely leaned over. My VN750 handles curves great, but there is no way I would push it anywhere near as far as a sportbike.
Sportbike tires are ridiculously expensive, and short lived, because they have to be made out of a softer compound for maximum traction. It's just the price sportbike riders pay.
There is no real reason that you could not make motorcycle tires that would last just as long as car tires (40,000+), except that they wouldn't be safe. Motorcycles lean over in curves and corners, cars don't.
With my own weight, plus all the accessories I've added, plus all the stuff I carry on trips, I'm pretty close to the Vulcan 750s load limit. Thats part of the reason I inflate the rear tire to the maximum psi shown on the sidewall. A good part of that weight is on the rear tire. I usually inflate the front tire a little less, to give me more traction when braking hard. Front tires are also quite a bit cheaper and easier to install than rear tires. Jerry.
I am a motorcyclist, NOT a biker.
