Hard to explain in layman's terms. It has to do with the clutch pack not fully releasing. There are lots of reasons why it may (or may not) fully release. Oil temp, previous plate separation, oil viscosity, oil additive packages components. Shift fork dog fitment in shift drum.
The easiest way to minimize it is to "pause" after you pull the clutch lever in for 1~2 seconds, THEN apply pressure to the shifter pedal. (From N to 1st.) Try it and see if it helps.
A clunk going from neutral to first is common on most bikes as the clutch plates stick together a bit because of the oil. It's worse when the engine is cold. Put it into gear and the transmission starts to pull, then the loading hitting the clutch causes the plates to fully separate and release. The clunk is the slack in the chain and gears taking up.
