After a long break 950 SM ?

Hey you, After a long search for a suitable SuMo I have just stepped on the ktm 950. I am approx. 1.88m tall, accordingly much the choice now on the 950s. Unfortunately I have no KTM dealer in my area to do a test drive. I used to drive a small 125er Yamaha DT (A1), I made my motorcycle driver’s license recently and in a few months I will be 25. What do you think that is too much for the beginning or still manageable ? Will just a pure fun Mopped, but also 150km drive through the Vosges… Greetings *edit*: I have just seen that there is about 40km further, nevertheless I would be grateful for answers…
