Not really. His primary contention is that the honing pattern on the cylinder walls acts like a rasp to bed the rings. Since the interior of our rotor housings is not honed, and has no pattern in it, that point is invalid for a rotary.

However, I do believe it may bevalid for a piston engine. I remember reading an article about race engine run-in procedures, which tends to support his theory. According to that article, crankshaft bearings are best run in at low speeds, while high speeds are best for bedding rings. Thus professional race teams will assemble a new bottom end in a "mule" engine and run it at idle for several hours to bed the bearings, before removing it and mating it with the rest of the freshly-built engine. Then, when they get to the track, they can open it up right from word go, because the rings need high revs to bed properly.

But again, I don't believe that that is the best course of action for a rotary.

this has been discussed here (and every other automotive forum) at least once before... search on "break in"

basically, the factory manual is condoning "spirited" driving for break-in (within reason), and not babying at all... this break-in procedure is for very high performance bike motors, and the tolerances and engineering goals in mind for something like a CBR motor and the RENESIS are completely different.

if i were getting this car, i wouldn't bother to deviate from what the factory recommends.
