Cheap running dirtbike /atv

I need something by this weekend for occasional use. Nothing special. 125/110 4 stroke pit bike, older 125/90 2 stroke etc. Looking to spend around $600.

I would consider a quad as well.

Got a crf150 honda dirt bike needs some minor things but it’s cheap, and does run well.

86 RM250 for $800

going riding out in NYC looking to rumble?

Bought a 125 Tri-Moto last night, lol. How much for the CRF150, just curious.
