My 2012 CBF1000 also does that, it's very normal. I think it's called easy start for newbies.
Appears to be an ECM function with clutch switch.
The clutch switch has two wires (very easy to unplug):
Black connects to green/red, which goes to
ECM B33
Start relay
clutch diode
Black/white connects to green/white, which goes to
ECM B22
side stand switch
If you disconnect one of the two clutch switch wires, I would expect the idle increase to cease. If left unplugged, the bike would need to be in neutral to start.
This is not likely related to the low/high idle issues under discussion. This may to be an ECM program variant.

The 2012 when you let the clutch out, RPM will increase 200 to 300 RPMs. That happens so it'll prevent it from stalling when engaging 1st gear. The 2009 CBF doesn't have that feature. I also read the last few pages on this and nobody mentioned cleaning their negative cable to the body. Sometimes corrosion gives you a lot of Gremlins. The one guy I remember that posted a few pages down changed his battery I wonder if he was able to clean the negative cable to the body so he didn't have any problems after that. The 2009 CBF is notorious for burning out stator. My preventive maintenance is to make sure that the ground cable is always clean and a battery gauge to monitor the stator output. So far, the 2009 is still running good. This thread really interests me because I have a used 2014 with 19000 Km that i'm looking at.
Amazing how many problems a corroded/poor ground can cause!
Although, other than starting, my biggest concern would be the three chassis/harness grounds:
Green/black for fuel pump and gauge
Green/white for ECM A22 & A23
Two green wires for forward lights, ground junction and ECM B4
There are three ring tongue connectors, but I do not yet know their physical location.
