Does anyone know what REV's to go when you have a brand new sports bike ?

Warning:
This is a very controversial topic !!
I wrote "Break-In Secrets" after successfully applying this method
to approximately 300 new engines, all without any problems whatsoever.
Links to this article now appear on hundreds of motorsports discussion forums from all over the world. The reason is that over time, large numbers of people have done a direct comparison between my method and the owner's manual method, and the news of their success is spreading rapidly.
The results are always the same. a dramatic increase in power at all RPMs. In addition, many professional mechanics have disassembled engines that have used this method, to find that the condition of the engine is much better than when the owner's manual break-in method has been used.
The thing that makes this page so controversial is that there have been many other break-in articles
written in the past which will contradict what has been written here.
Several factors make the older information on break-in obsolete.
The biggest factor is that engine manufacturers now use a much finer honing pattern in the cylinders than they once did. This in turn changes the break-in requirements, because as you're about to learn, the window of opportunity for achieving an exceptional ring seal is much smaller with
newer engines than it was with the older "rough honed" engines.
In addition, there is a lot less heat build up in the cylinders from ring friction
due to the finer honing pattern used in modern engines.
The other factors that have changed are the vastly improved metal casting and machining
technologies which are now used. This means that the "wearing in" of the new parts
involves significantly less friction and actual wear than it did in the distant past.
With that in mind .
Welcome to one of the most controversial motorsports pages on the internet !!
Depends on the bike as to max revs, whilst your running it in for the next 500 miles, keep it as low as possible.
Not sure about revs, all depends on horsepower But for running it in running in 700 klm
If my long term memory serves me right, for the first 500 mls up to 3000, then up to 4000 revs for the next 1500mls.
Check with your dealer though as I may be talking out of my exhaust system.
go by the handbook, but you'll know when its run in when the exhaust makes that sweet sound. it only lasts a few days but you'll notice it.
max to be two thirds below your first red rev line, if for eg, red starts at 9000 do not go above 6000, but for the first 500 kms keep it a bit lower
The generic and general rule for todays motor break in is: To much of any one thing, is bad. (like when your on a diet!) To give a number to keep the rev under is impossible. Many bikes today dont move until your rev'ing over 4k!
Dont cruise at constant throttle for long
Dont rev to redline constantly
Dont idle for extended periods
Dont overuse the brakes
You get the idea. Run it like you normally would without doing too much of any one thing. Dont baby it.that just prolongs break in.
How long is break in? Until the first recomended oil change. Could be 500 miles, 1000k, or more. Read your manual.
You should bury the needle often and for extended periods of time. Ignore the redline, just go for it.
the best is not more than 5 rpm for about 1500 - 3000km mileage..
after that change the engine oil.. after that just GOOOOO as fast as u can.
Hello. When you have a new bike or car or anything with a new engine, you should never rise past the half mark of your rev counter. i.e if your ride revs to 8000rpm don't exceed 4500rpm. This is because the engine is designed to wear, the pistons, valves and crank shaft are micro millimeters bigger than they should be. Hence if you over rev your ride high friction will occur and it will go pop. But for how long? 2000 miles is plenty. After that, rev away.
