Congrats on the new bike, hope you have many safe and trouble free miles.
To answer your question truly no one can tell you its a one off thing, but if you were to ask texas_103, he has a 2011 SERGU and with less than 2k miles the crank was out .006+. Inherently I think the leaks are gone, but the piston slap, crank runout, and overall heat from this engine are still there. How long will each last good question, longest I have seen without issue seems to be 25-30k miles and then something seems to bite the owner. Best advice is either buy and extended warranty or take the bull by the horns and make the needed modifications to make the motor last.
Put on pipes / A/C and tune the motor.
Change the cam to something that has overlap
To go one step further:
Crank weld pin / true balanced
Check the heads for guides / valves etc
Dont have to go crazy on mods of the motor, but just enough resolve the moco's epa compliance and cheapness.
