G'day guys,
just a quick question as i have forgotten the recommended max revs for a new bike.
I remember the tech guy @ Flywheels saying someting about DO NOT go over ??? revs before the bike reaches 400ks and than DO NOT go over ??? revs until the bike hasn't reached 1000Ks! If anyone could help me out with the answer.... im staring to "stretch" a bit but bike only has 110ks so far...
BTW, the bike is an ER6nL.
Thanks

Never worried about max revs....just don't strain the engine by not having enough rev's.

Basically don't over "load" the engine by having it in too tall a gear for the situation. Keep it singing at the point where it stats to come on tap if not a bit higher. So i would say keep it at around 1/3 to half revs, maybe a little higher, at 1/3 revs if you find your starting to have to really open the throttle to get anywhere, your loading the engine and you need to shift down a gear or two to keep the engine at the right load.

sweet, thanks for the answers
i thought it was a matter of letting the engine sort of "break in" first

Read your manual, it's in there and that will be overly cautious...... or just go until the rev limiter kicks in

just get into em after 200 on the clock

There are two components to "breaking in the engine. Letting it run but not overly fast so that the rings and piston/bore can bed into each other by moving, but not too fast while they are still pretty tight as they could bed in incorrectly. The second is the rings, apparently "loading" the engine puts a vertical load (think of the up/down direction of the piston) on the rings and their edging, which somehow causes bedding in problems with the rings. This is why you run it, but not too fast, but not straining it terribly either.
As to accuracy of this, im just going on what others have said here and elsewhere about the matter. it makes sufficient sense to me and is how i ran in the gsx when i replaced the rings on it.

Ride It like ya stole it ! Best way of breaking in any motor.

@ mike-s,
cheers mate ( and every one else too), your post sounds more like what someone with a bit of tech knowledge would say.
Ride it like if i had stolen it??? HELL YEAH! but im not ready yet.... only learnt to ride a manual bike 2 weeks ago
anyway.... i'll get there

The oil that came in the motor is called break in oil and has less of the extensive friction inhibitors that regular, (quality) motorcycle oil has. This is so the rings as previously stated will seat properly on the cylinder walls. This matching is necessary to keep the oil from slipping past the rings and to give you the compression on the power stroke that you should have. Also the main and rod bearings need to bed in to match the rod and crank journals. "Riding like you stole it is a bad idea, also a bad idea is to baby it while you are breaking it in. The rings will not seat properly unless you have some full throttle acceleration on break in, also cruising at a constant speed intercourses things up as well, (don't keep the revs at a constant RPM). So in my extensive and farked up 50 years of riding experience says to follow the max revs in your owners manual without staying at the same rpm for long periods with the occasional full throttle trip to red line. By driving it like you stole it you will probably be ok but there is the off chance that you will end up farking the dog. If you are like me I could never let a smart arse cage pass me without showing him/her who had the power. Jim Beam, Vodka and a brew will make all that is true come to light.

Funnily enough, your bike has already had a full on dyno run at the factory so they know how much power it's making....can't see that babying it now is going to make much difference

I gotta be honest, i was kindda of babying it a little with an ocasional up trottle just to feel what the "baby" is capable off....
since i've got some good tech advices here @ksrc, im gonna change behaviour towards my bike and be a little more agressive now
Any sugestions of a good long ride with not much traffic around the eastern suburbs in Sydney?
Also, if any novice riders out there wanna catch up for a ride, give me the heads up!
Thanks for the all the tips mate!

100k isn't much. I have an ER6 and behaved myself until the first oil change at 1000k. There's more than rings to be bedded in, the whole engine drive train, gearbox bit need to work together. Stop start riding round the suburbs is good as it varies the revs. You can feel it loosen up.

+2. Leanne's 10 has only got 600k's on it so far and hasn't been babied at all. It's maiden voyage was a spirited trip up Mac Pass with me struggling to keep up on the ZRX and my first go on it even involved a brief visit with Mr rev limiter

(just don't let Leanne know about that one). The guys that race them don't break them in first and they don't seem to have any power loss issues and the engine has already been taken to red line on its dyno run at the factory as Mick pointed out so I can't see riding it hard doing any real damage.
