I will be picking up my R today with its new motor and was wondering what is the max RPM I should hit during break in.

I was thinking it was around 6 but not sure. Dose anyone know?

Thanks
Russell

I'm pretty sure break-in procedure says to keep it below 6k RPM if I remember correctly.

.......and equally as important, is not to 'lug' the motor at low revs. Just keep it spinning freely and don't do anything daft with it. Vary the throttle position - lots

Break it in like you're planning to ride it with these caveats: no sustained periods of constant RPM, keep in the range of 3-9K, try not to bounce off rev limiter, at least not right away.

It's really hard to break in the 1125 per manual due to gearing and the desire of the beast to RUN. The motor I'm running now was broken in on a race weekend, and I probably violated at least two of my own caveats - so far, so good.

"It's really hard to break in the 1125 per manual due to gearing and the desire of the beast to RUN. "

and the bike isn't any fun to ride that way either!

Just ride it in a normal fashion, as stated no lugging or redlining, vary the rev range and fegeddaboudit.

Put 30 weight oil in it. Get it nice and hot at idle. Get on it, run it up to the rev limiter and all the way back down, in as many gears as you can legally do. If you have a dyno, use that instead. Do this about 5 to 10 minutes or until you notice and increase in power and acceleration smoothness. At this point your rings will be properly seated.
Go home, change the oil with a high quality synthetic 10/40 or 20/50 oil, and filter. Make sure you get all the oil out of the cooler too.
You motor is now broken in.

Maybe like this? Skip to 3:36 for the motor running if you don't want to see it all.

I generally like to listen to the engineers that designed it, helped write the manual, and work for the company that to warranty any problems that arise if they are wrong

You mean the lawyers that rewrote the manual?

All you have to do is read the first 20 pages of the manual to know who approved the final draft...

that's funny -- I've talked to the engineers who designed the bike, and they told me they had no idea why the "parent company" put a lot of stuff in the manuals.

I'll grant you that, between lawyers and boilerplate, there is stuff in there for other reasons
