There is a contender locally for a new 30hp Chinese dirtbike at a high-ish price of $4200 on sale (normally $4600) at a dealership. Not bad really considering the build. I didn't know it existed.
This is a 2021 SSR SR300. But this 300 is not available in a street legal form.

They have a 250 as well, pure dirt OR in a street legal dual sport at $2999 (normally $3499) making 18hp. But that is only modestly more attractive than the street legal offerings from Lifan, Bashan, Orion...at prices at least $1000 less, ya' know
These are dealership supported models, so the additional expense is "justified". The high-end in the lineup is the SR450. It can be had for about $5000, which is less than HALF of the price of a KTM. That would be fun
