2-stroke fan is looking for interesting modern 4-stroke second motorcycle !

Hello, as a fan of 2-strokes (Yamaha RD 350 31K) I am still looking for a “more modern” second motorcycle. Since there are no new 2-strokes with road registration, I am looking for an interesting 4-stroker around the 50-60 hp, possible high speed, super sound and good seating position (sportsman, nakedbike or supermoto). I am overwhelmed with the offer on the market and hope for some good tips here! Greeting Peter
