To those of you that ride motorcycles

I've started mtb rather late, in my late 30s. I suck but I did progress a bit over the years.

I'm considering getting a motorcycle. I've never ridden one except for a 2h riding lessons.

I'm concerned that riding a motorcycle will destroy what little skills and muscle memory I built on MTB. What's your take on that ?

Also keep in mind I'm 40+ and without much experience in either, so my brain may not react like that of a 20yo.
