First of all, congratulations and enjoy Your bike.
Limitation for the back in is simple, I just finished mine Yesterday.
For the first 300 Km or 186.4 Miles try not to rev the bike too often, do not exceed the 4000 to 5000 RPM, this will limit and answer Your question about the max speed. You can overtake but do it ever so gently. May I advise You to play a lots with the gear box as well during this period, it will ease a lots afterwards.
Then after try to limit Yourself from exceeding the 5000 to 6000 RPM until the first service. I allow myself to go at 7000 RPM for a minute while heckling the engine temperatures for a minutes when I reached 750 Km or 466 Miles, then up to 9000 RPM on my way to the first service. It is my experience as I had all the bikes below brand new that a little restrain for a little time makes Your Bike a better machine in the long run.
Other than that ride it as You see fit and happy too.
135 LC, 350 XT, 600XT, FZR 600, Diversion 600, ZXR600.
Enjoy Each Days:wink 2:
