What revs to sit on?

Postby clay » Sat Oct 24, 2009 8:41 pm

I've just passed the breaking in period on my 2009 Ninja 250R. Prior to this the manual advised not exceeding 6K.

What should I sit my revs on when in gear now? 6K, 8K or what? And at what rev range should I change gear? 8K?

Redline starts at 13 I think. I bounced the needle off the limiter for the first time today when in 2nd gear, felt nice, sounded pretty sweet for a 250 too :D

Thanks guys.

In town I try to be at the bottom of the power band so I have good engine braking if I roll off and acceleration if I roll on.

Power band starts around 7k I think, so cruising around town I would stay in 4th or 5th or what ever keeps the needle just below the power band. If you need to pull away in a hurry you can gear down and power on. Or if you need to stop you can shift down and apply brakes and have so e decent engine braking to go with it. Edit: basically what Dilli just said.
Also I wouldn't be too concerned with what the book says, the engine is broken in before it's fitted on the bike. There is a website that explains how to break in engines and it basically contrdicts everything the books say. Hopefully someone that knows it can post a link up for you

For me, it depends on what type of riding I am doing.
Tyra redlines at 13k.
If I am just cruising I sit at low revs, 4-6k because it saves fuel and being at low revs make me feel relaxed.
If I am riding aggressively I will sit in something like 6-8k so I have power if I twist my wrist but of course, it depends on what is happening at the time.
There are variables to consider.
I do not know if that helped or not but there it is.

As for the 250, give it a proper warm up then rev its tits off.

Sweet, thanks guys.

I guess if I'm in a fuel saving mood I'll keep revs <6K. Otherwise, I'll keep them above 6 ,like 6-8K. And if I feel like revving its tits off I'll keep them around 10K :D

After reading that article on break-ins I'm a little confused now. I mean, mine was broken in according to the manual, so I'm guessing it's not as powerful as it could be. Thank God it's only a 250. But when I buy a bigger bike, I'm not sure what I'll do. I mean fanging it straight away seems like it would damage the motor, thanks to all the conventional things I've heard. But according to this fella its actually better for the motor. Something to consider, it'll be a while before I get a bigger bike.

Believe it if you want. It's just one "Experts" theory. Don't believe everything you read on the net.
I see this one piece of diatribe trotted out regularly and "Sworn by"on this forum. It makes fuck all difference and could possibly cause long term damage due to premature wear. The break in period on any new vehicle is to make allowance for tight tolerances and allows all moving parts within the engine to mate together.
Clay you have done the right thing and are none the worse for it.

I have no idea if it's good or bad advice. I only linked it because someone asked for it.

There is contravercy everywhere with regards to break in... I know some machanics that say one thing and others agree with another... Some say stick to the manual others say ride it like you stole it... I think I sat inbetween both methods when breaking in as it in near on impossible to stick to the book (letter for letter) on the little babeys anyway.

But yeah... When trotting around local streets I won't go over 5th gear (around 5k at 60) seems to sit nice and give me potential to find useable power easy enough (sometimes this means shifting down)...
Do what you do, and do it well...

i have learnt to just let the engine tell you what it wants, if ou hit a corner and upon exit it is sluggish then you know your revs are to low, with more riding youll see what your 250 likes, give it time and youll be soon riding the tits off it mark.

Sounds like yet another "experts" theory! Who's right and who's wrong??? Dunno, but I have been riding bikes for a long time and had lots of bikes. I run my bikes in relatively hard without banging them off the limiter and my engines have always produced good power, never used oil and have done loads of klms without premature wear or failure???? I'll keep running mine in that way regardless of your "expert" opinion!

A great example of this, is a mate of mine who bought a 954 blade new and rode it hard from the get go. It just clocked 200,000 trouble free klms (apart from 4 Stators, which fail at 50,000klms almost on the dot!!) I doubt you could convince him of any other running in method!!!!! :lol:

I still think the key to a long engine life is simple...clean oil!!! ;)
