I have no idea about motorcycle engines but with automobile engines they are in essence broken in before you get them, usually before they are even installed in the vehicle. Most engine manufacturer puts them through a really strenuous test procedures that includes running them at RPM's most car drivers would never see. It is not uncommon for owners manuals to not really have a true break-in procedure anymore as a result.My next door neighbor was a machinist. He was the guy you went to with your Ferrari to have the heads redone. I asked him about the two break-in methods one afternoon...and got a Master's thesis on the effects on the cylinder wear and rings, oil, etc. I'd say 95% went over my head, but even the 5% I picked up, was impressive. He basically said to ride it hard for the first 100 miles or so to get the rings seated properly. After that, there was nothing you could do.




Here is the proper way to break in an engine,, wait till the endToo late now, but I'd forget about the 4000 rpm break in method.
Just a question to ponder...when you buy a demo bike, does anyone really think the rider ever thinks about the 4000 rpm limit? Nah... We buy it and it runs perfectly forever.
I had two Suzuki Burgman 400s. With the first one, I tried to ride it gently though it is impossible with a CVT rubber-band tranny to keep the rpms under 4000. I put 48K on that bike. Then bought a leftover 2008, identical except the color. On that one, I took the opposite method for break-in. The bike had 20 miles on it when I picked it up in Port Angeles, WA. I immediately took it out to the road heading to Hurricane Ridge in the Olympic National Park, revving it as hard as I could, backing off the throttle. On and off, like I believe the Motoman break-in method is. I think I had 38K on that bike before I sold it.
Both bikes ran the same afterward. Neither bike used oil before they hit the oil change interval. I did my SS1000 on the 2008 Burgman and after it was like "is that all you can think of for a challenge?".

Russ.I had a memorable conversation with a guy at Mt. St. Helens a few years back. I had my 2011 Black NT700V...the little brother to the ST1100/1300. The guy and his buddies were on BMWs and when he walked up, he wanted to know what BMW model I was riding.I traveling with two friends on BMW's. Stopped at Mariposa for lunch and a few people walking by asked about the ST, not the BWM's.
