Hell, it's impossible to ride the bike at less than 4K. It keeps making your throttle hand twist. I think it's some desease that creeps into your hand...makes you go faster and fasterMuddy said:

If you are referring to breaking it in, the RPM is almost irelivant!Muddy said:
Because REAL ENGINEERS who designed the thing actually understand the breakin process and would never break it in this way in the first place!scarter said:Pg 58 owner's manual for 05 states 7000 rpm max for first 1000 km.

What matters is not to expose the motor to excessive load (and thus heat). It is FAR better on the motor to allow it to whizz along at 6000RPM under light throttle load, as opposed to shifting up 3 gears and slogging along at 2500 or 3000 and thus requiring a lot of throttle opening to keep up the same speed.
Actually, the one exception to avoiding wide throttle openings duting breakin, is when seating the rings.zzrman said:I agree, that's why I did the high rev runs on the downhill leg of the bypass. If you don't bed the rings in early on, you'll never bed them in properly.
You also need to bear in mind that they should have bench tested the engine at the factory to make sure it delivers the promised power and torque, so the engine will already have been up there at peak revs.
Suit yourself. But there is nothing at all magic about those RPM numbers. They are there only because Marketing wants to approach this as if it is a "Break In For Dummies" book. The engine (and in particular the rings) will benefit greatly by momentarily exceeding these arbitrary numbers, provided it is done properly with the understanding of the Engineering principles of breakin.Muddy said:This will be interesting. We may need to add a third category though. "Keep it to 4000rpm for xxx miles then as per manual" or something similar.
Thanks for all the responses so far from which I'm going to follow this procedure:
0-200miles - <4000rpm
200-400miles - <5000rpm
400-600miles - <6000rpm
All miles with no large throttle openings and plenty of throttleing back to bed things in. I've always been told not to 'baby' new engines but neither am I going to exceed the max rpm recommended in the handbook.
Guess I've answered my own initial question. Can't wait for the poll results
