not long ago i put on a shinko 777 rear and BT45 front and i have to say i don't like the BT45 at all, I'm not saying it isn't a good tire but i just don't like it myself and will never buy it again, it looks to flimsy and narrow, don't handle good on my bike, it follows alot of ruts in the road and i can feel it in the handle bars.
My last front tire the avon road rider was good and i got around 19k but i don't see that happening with the BT45.
the rear 777 is great and i'm on my second one, think i got about 11k from the last one.
