I would not say novice.
A person has a better chance of learning to ride a motorcycle of anykind if they have ridden a bicycle. They at least will know how to balance and shift weight and turn. It is a start and at least gives a base to start from.
I rode my dirtbike all over, on and off-road. Then after years of not riding but maybe once or twice a year, I got my 750 and off I went.
Aside from being heavier and of course top-heavy in the first place, I learned to ride it quite quick and have never dumped it for any reason. Got close in my garage but was able to keep it up one-handed till I could get better leaverage to get it all the way up. It never went on its side though.
While I do not claim to be an expert at riding, I do not exceed my limits but gradually increase my skill. I am a bit weak in corners but that is because we do not have any here! The damn norwegian method of road building here is a bit lacking on corners, they are good at arrow straight though!
