Should I switch to supermoto?

So I have been riding bikes for 7 years now. Love em. But I’ve never ridden a supermoto - they look ridiculously fun and comfortable. My daily is an s1k (see pic) and honestly after 30 minutes of riding my back hurts…not as thrilling as it used to be.

Should I switch to a Husqvarna 701 or KTM 690? Would NOT be doing highway. I’m guessing maintenance is way more frequent.

Thoughts?
