I have a set of stock size Tourmasters on my bike, and I like them a WHOLE lot better than the IRC Durotours that were on there. The handling is a LOT better, I'm finding myself leaning more in the corners with a little more speed, and they do feel a lot more stable and it has a lot less wobble on uneven pavement. I have ridden in the rain with these tires, and they are good so far.
I'm still learning this bike with these Tourmasters on it, and so far so good.
I'm still a little unsure of myself after not riding for a number of years, but I do like the feel of this bike with these tires on it.
