The RC51 has an abrupt clutch engagement. It's just something to adapt to.
On the SP2s, they added a judder spring and seat along with larger I.D. friction plate to try and make the engagement a bit smoother, but still they hook up pretty quick.
If you clutch fluid is nice and clear and not cloudy, then you should be ok.
Now if you have no lever travel at all, then the cup in the master cylinder may be worn and not maintaining pressure when actuated.
Does your bike tend to creep more while the clutch is disengaged, even more so than usual?
A squeaky clutch lever is usually caused by lack of lubrication of the lever pivot bushing.
Just remove the nut and bolt, then remove the lever and clean the bushing on the lever and pivot bolt.
Then apply some lithium grease and reassemble.
