If your bike came with bt-016 PROs I'd say just ride em. The original 016's were great tires.....for the first half of their life. After that the front wears faster than the rear and actually starts coning, creating a triangular profile. Almost lost the front end midturn cuz of it. Bridgestone apparently fixed that issue with the Pros.
But yeah, these K3's.....best tires I've ever had so far (2000 mi as of now). Super sticky
