If the rear rim is a 4.25" wide rear, you'll need a 150. The 160 would be better suited to a 5" rim. No experience with the pilot pure's though, sorry.
It will clear the swingarm fine, bit won't have the correct profile. It will be squished and have a smaller contact patch (less traction)
wouldnt that be less in the middle (where the compression of the tire would be of most consequence) but result in a somewhat flatter sidewall?
Not sure what you mean, but the contact patch where the tire meets the road will be smaller, as well as the handling/performance of the tire will be affected. Hope this helps: There are a fee good tires out there in a 150. There were a few pilot models in a 150, though I'm not sure of it was the old pilot powers or what.
nice art almost looks like you might have MORE contact area when leaned over though...no one needs contact patch in the center :-P
I put a 160 on my bike when it was time to replace the stock tire, I didn't like the 160 because the 160 looks great but will not turn as well as the 150... That is nice art, a picture is worth a 1000 word
It seems to round out the whole tire, making contact patch suffer regardless of lean angle. My picture isn't quite that good. All I have is a pen and notepad.. no protractors, etc.. Pics usually seemed to explain better than words, and I like to draw
