What's the break-in requirement on this bike? I know a lot of sportbike owners drive themselves nuts for the first 500 miles or so, trying to keep things below 5000 RPM or so, but I don't know anything about the 300's requirements.

Well, the owners manual will give you the "correct" break-in for it, but there's a lot of different opinions.

I recently spoke with a pro engine builder who has experience building Nascar and Pro Stock engines about "break-in". He said that because of the tight tolerances, precise fitting, and advanced honing techniques used today the break-in of old isn't required.

They run their new engines up on a dyno at 40% for 1 hour, then check it with a leakdown test to confirm the rings are seated. He liked conventional oil initially, with a quick oil change to Mobil1 racing oil (for the auto race engines) before it's run in the car.

One thing he said surprised me. They run 0W-30 in almost all of their race engines. Lot of people like to go to a higher grade than recommended in their engines because they think it gives better protection, and they go with a lower grade than is typically recommended for street use in the specific engines.
