Don't worry it's normal, the clunk sound is like shifting from N to 1st gear. If you change your oil you may not hear the clunk in 2nd gear for a little while.
It's normal but there are ways to shift without "clunking" it. What I noticed is that if you time the shift right when you release the throttle (and don't push it all the way up, but just enough to "catch" the gear), it will be a lot smoother, as if you are shifting normally from 2-3, etc. And you wouldn't even need the clutch to shift this way either, but that's a whole 'nother debate.
If I short shift to second gear at lower rpms, no clunking. I get the clunk if I shift at higher rpm's. Not sure if you can shift to second gear without the clunking sound at higher rpms. If there's a way, I haven't been able to do it.
interesting! i noticed the very same thing on my brand new 600RR, the clunk from 1st to 2nd, I was beginning to worry that I was doing something wrong! i can make it almost non existent if i release the clutch really slow and get the RPMs just right...
...but there's a twist!!! SOMETIMES, it will shift without any noise, BUT it will clunk when I release the clutch while transition is already in 2nd. what's up with that?!? again, the bike is brand new and i've been taking it pretty easy and i don't shift above 8-9K RPMs.
what do you mean "when you're on the power"? do you let off throttle when doing quick shifts? i struggle with that... getting the revs right between shifts... this was much easier, or the bike was more forgiving, on a cruiser.
so i should push it harder, more firmly, when going form 1st to 2nd then?
i don't have this problem when going up from 2nd, and the rev adjustment is easier in higher gears...
Clunk? I only get that when going from N-1st or N-2nd whilst stopped. Shifting is pretty smooth everywhere else. It can be a bit rickety going from 1st to 2nd usually, but that's all vehicles since the ratio between them is the largest.
You shouldn't be slamming the shifter like it's a Harley or something; you could bend the shift forks which will ruin your day and also keep in mind since neutral is between 1st and 2nd so perhaps your muscle memory is throwing the timing of your shift sequence off just enough when done too quickly...coincidentally I have a very similar technique as tary; shift into 2nd at about 5k using the clutch, without the clutch from 2nd to 6th, but I use the clutch when downshifting and of course blip the throttle.
Also, the engine and gearbox on these bikes share the same oil...it may be in my head but I think I notice a difference in the shifting when the oil needs to be replaced...have you checked yours lately?

The clutch isn't what make that noise anyway, it comes from an internal part of the transmission because the noise occurs when your selecting a gear...a friend of mine builds transmissions for racing as well as fixed them. That's what he told me and I believe him.
well there was before; on a brand new bike with 100 miles on it so far; somebody suggested i was not shifting all the way, so i made a more firm shift from 1st to 2nd and the cluck when releasing the clutch (smoothly) went away. still a clunk when shifting though, but it gets better if i shift at higher RPM and try to do it smoother
If shifting is that clunky you either have an actual issue or more than likely your timing is off.
Practice being smooth: move foot to shift lever, very slightly "preload" the shift lever, throttle off, clutch in, shift the lever, clutch out smoothly, throttle roll back on; one fluid motion for all of it.
One hint: there is no reason to fully pull the clutch in on an upshift, all you need to do is get it past the point the clutch engages and releases pressure on the transmission, make your shift then release the clutch. MUCH smoother shifts will occur.
Fully pull in the clutch and blip the throttle on downshifts before releasing the clutch, however.
There are many schools of thought and discussions on clutchless shifting which I will suggest to hold off until you can do the above without creating a jerking motion or you will cause damage to your transmission.
I don't know if you realized this but you just rephrased although also elaborated on what I also outlined a few posts ago, which means we kinda just agreed on something...does this mean the world is about to end?
I think it's normal dude, sometimes I get loud clunks and sometimes I don't, it doesn't seem anything major to me. I do notice when I've been riding the whole day I get clunks a lot but it could be the oil viscosity or maybe my oil needs changing, it's pretty black.. I have no idea yeah I know I don't know that much in mechanical stuff lol
Like I've said: I know a mechanic that builds and rebuilds transmissions for a living and even looked at mine in front of me to prove there was nothing wrong with the components.
If your oil is doneski, change it along with the filter and see what a difference that makes in the smoothness; just like in a car if you're always revving to redline the oil will need to be changed sooner, and keep in mind the engine and gearbox share oil.
having N between 1 and 2 doesn't actually affect lever travel. if N wasn't between 1 and 2 it would still shift the same, the clunkiness is a result in the difference in ratios, nothing to do with neutral.
