No, you're not confused, R01's are 100% asphalt.
That is why they're noisy, especially at speed. I had them on my Tiger also which I came to from an enduro bike (WR400) and I have to say that 20% offroad ability on a 250Kg bike isn't much help unless it's hard packed earth or you're very good, which I am not. But there again, I did, as I say, come from a bike that had full-on knobblies so it felt very unstable to me in comparison. I don't offroad mine but if one is going to there really is nothing like a set of knobblies for doing so, and even more so on a heavy bike.
They are good tyres, though, no question, if you can stand the noise.
