Ah, the anticipation o.f a "new and improved" model beyond the PR4. We will have endless tyre treads.
Talk of grip, tread life, cost, fitment the list goes on.
The motorcycle tire selection has never been better.
I had Goodyear "Grass hoppers" on my 64 Sportster and though they were great.
What vintage tyre did you have on your first bike??
