I have a similar one. I remember being told by someone back in the 1980's that Porche did a test of two Porches.. both were tested and found even. Then one was ragged most of its life, the other was treated to pampering and barely left the garage. After a while they re tested them back to back. The ragged one was stronger.
Now that was a cheery anecdotal tale of two Porches, clouded by distant memory, recanted by some beer assisted bloke (me) off the internet Might be true
I can believe this, I bought a zx9r that was a fast bikes magazine demo bike, it wasnt even run in, spanked from the moment it was first started, by all accounts they dyno tested a few bikes that were released that year when doing a group test later in the year, the zx made more power than the others and more than the manufacturer claimed hp where the others were all a fair bit lower.
How long it would last is a different story.
The problem with "running in" people take it too literally, i.e dont go above 4k rpm for x, so they dont, in reality you should give it a few revs here and there, you just dont want prolonged high revs.
