As long as you change the oil after flogging a brand new bike like that, it shouldn't hurt the motor.  I agree with the theory that wailing on a new motor actually seats the rings BETTER than pampering it for 500 miles.  It is compression that expands the rings against the cylinder walls anyway(not the rings themselves), so the higher the pressure, the better they should seat.  Go buy that 750 you rode.  It will be the fastest one in the frozen north!

I disagree.  I think if it WAS OK then WHY does the factory (the ones who designed and built it) say no?  For a RACE motor that will only go 500 miles before a rebuild, sure, I can buy that.  But a motor you want to run FOREVER, nah, I'll do like the designers say.

A few facts for you to help in YOUR decision making:

At 5,000 RPM the crank is turning at 80 RPS!  That's turning 80 times PER SECOND.  That's pretty darn fast if you ask me.  That means EACH piston is going up and down 80 times a SECOND.  Again, REALLY fast for a new engine.  Shouldn't that be fast enough to "mate it" properly?

I'd personally like all the components to find their "wear" spots and smooth out all the mating surfaces at that "reasonable" speed rather than at the increadible speeds of red line.

On my Ninja it's 14,000 RPM, 230 RPS, and 230 piston up and downs a second.

You've described the counter point to the break in theory.  There are many that say breaking in a motor at high RPM will increase its life and power.  

But who knows.  Somebody would have to build two identical motors to know for sure.

Its only frozen in winter!! common. it aint that bad up here. haha. I ride my GS with spikes in my tires.

I'm still not sure which is the best method, IMO, but just to play devil's advocate:  do you really think any manufacturer is going to RECOMMEND that you take your brand new, 180hp bike home and tach it out on the first ride?  Sounds like a seriouse crash and a lawsuit waiting to happen, doesn't it?

No, not really.  Only because the car manufacturers ALSO tell you to do the same thing.  Keep revs low, drive in a manner that will give you a wide range of speeds.  They suggest driving in traffic, lots of stop and go.
