Yup, but how much do we trust it is the question? I know I'd rather have a bike that was broken in hard than too soft, that's the worst option of all. Barrels and rings definately seem to like a fast break in, who knows about the rest? If I ever do my busa piston swap, I'll be getting YPE to run it in on their dyno for me, since the bottom end's nicely run in at 30-odd thousand miles
(plus, it was a demonstrator once so it was probably doing wheelies the day after its 500 mile service
