I've read time and again how much better the BT45 is as far as mileage, wet traction and longevity is concerned. I've also read how this is not the tire to use if one plans on spending time carving through the twistys and that the G709 is much better suited for curves. My question is since both are "motorcycle tires," even if one is designed for the rear end of a bike, how is one so much better than the other? What's the basis for this assessment? Will the BT45 fail me if I'm getting to aggressive through a stretch of curves? I went through 2 709's before switching off to the BT45 and while I'm certain I'm not anywhere near as skilled as yellow wolf or others here, I'm very curious about the differences between these two otherwise very popular tires. Thanks in advance!
