Still not as soft as a Car Tire according to Durometer readings and thanks to correct pressure setting still almost twice as thick as motorcycle tires stock contact patch, unless of course it's a well used MC tire which has that large flat spot on it that you can actually feel yourself going over the side of onto that special, stickier part of the tire you mention on dual compound tires. You seem to miss the fact that we've had MC tires on, plenty of them, and we wore them out plenty. A bunch on the center but plenty on the edges as well. Then we changed over to a Car Tire after being told we'll crash and burn and tentatively leaned over for a while until we were on the pegs and then in wonderment, we did it some more and we did it hard and we did it in the rain and we did it in the snow and we did it through gravel and dirt and whatnot and then we started wondering just what side of the bowl you 'Experts' with your special motorcycle tire,rubber, shape, physics, boca boca bullcrap were eating your oats out of CUZZ IT JUST AIN'T HAPPENING.
We generally put it down to folks that mean well but are just ignorant of the fact that not only does it work, it works better.
Why don't the manufacturers have them on the bike when they come from the shop? Because the ignorant masses that mean well will tell everyone they will crash and burn if they don't have a Formula 1 tire on their bike and there will be tons of folks that will listen to those that mean well but have no clue. And tire manufacturers will look at all the OEM only tires and say 'Screw it' we will sell them direct and cut the dealer out of another percent if you let the cat out of the bag.
Meanwhile, those of us running on 6 inches of tire straight up and 2-3 inches when over on the side will still be going down the road and tearing up the twistees.
You see, 2 years ago I was in this spot, asking the same questions, can it be done on a 900? What should I use? I'll bust my what? I had guys telling me they were doing it. I had a web-page telling me how to do it and that it can be done and a list of all the bad things that will happen from folks that never had tried it before because they 'knew better'. A year and a half and nearly 19 thousand miles ago I made the switch anyways. The naysayers with all their extrapolated physics and Piled Higher and Deepers and their insurance this and dealer thats were just wrong. Pure and simple, wrong. And they don't like and just flat out WON'T admit it. It's actually funny watching someone watch you ride away or doing peg scraping circles in the parking lot when they know, not think mind you, KNOW it's impossible. Then I park the bike or see them again and they just spout the same lines 'It can't work'. I'm told Orville and Wilbur had a bunch of the same response. 'It can't work, mans not supposed to fly' but here they were up and doing it.
I will force no person to use a Car Tire on their bike. Some bikes have too narrow of a rim anyways. Other bikes like the Ninjas lean over too far and probably would make the tire go over the edge. But most cruisers and definitely the Vulcan class here with the wider rims and low lean angle work wonderfully well on a Car Tire. You won't go wrong with a stock tire. If you don't ride enough miles in 4 years to wear out a Car Tire, stick with stock. Don't want your tires rotting out from under you. I'm ordering my next car tire this week so I can have it ready in the middle of the winter when I project this tire will be worn out. It will be a factor in the purchase of my next bike.
If it's not for you then that's fine with me. But quit it with the long extrapolations of why it won't work because it does. Ignorance is the lack of knowledge. Stupidity is the inability to learn. Stubborn is the un-willingness to learn.
Lotta Stubborn people holding the ignorant back and that's just stupid.
