I went with the Shinko 140/90/15 rear, still got the IRC junker in the front (at 7200 miles)
I will go for the Pirelli for the front, and the Pirelli 130/90/15 rear next time, assuming I don't Cafe the bike or some such
I think the Shinko is resisting tipping in (or maybe it's the IRC front)
140 is definitely more tire than a Savage needs IMO, and my bike squirms when I try to lean it very far (I don't remember if it did that with the original rear
The Shinko is wearing well, and has all the traction I need and then some, and sticks well in wet weather
