I just replaced my stocker BT-014. I burned that one up pretty quick and needed something with a bit more life.
I mounted a BT-021 rear along with the original BT-014 front. The combo feels like a new set of BT-014's. I just went out for a 30 minute ride and didn't push too hard. It seems that the two tires have similar profiles and I didn't notice any handling issues or differences.
I will update the mileage later.
...Bologna music, there is nothing, and I mean nothing, sounding like an aircooled 2V Ducati engine pumping out the music through a full and open exhaust system. Knees buckle, conversations cease, and time stands still when such a thing passes by. -stolen from a random post from an anonymous member on esportbike.com
