I would not touch BT014s again. 1.5K miles and the rear was toast, usuable for longer but any fun was long gone. I really don't think I could really rate em for feedback either. Just my opinion on my bike. Diablos on the other hand have doubled that milage on my bike. I'll be trying the Corsa III variant when it's next change. Some peeps love the 014, I am not one of them.
