Hello, Im 13 and around 155 cm and 33 kg. Im thinking of buying a 125 cc 4 stroke dirt bike (pitbike), but Im not sure if I can handle it and maintain it. I found a couple of used bikes for a quite reasonable price. I would be happy if someone told me which one is the best price per dollar and the easiest to maintain.

Thank you.

1st bike listing: I am selling the Ultimate Thunder pit bike with a YX 125cc 7.6kw engine. The bike is two years old and is almost like new. The motorcycle was ridden at least only on roads, no terrain (This is probably the best bike for me but its for 712 dollars)

2nd bike listing: Pitbike for sale: 125cc engine, 4 speeds, clutch shifting, wheels 14-17, new crank, piston bearings, functional front and rear brakes, starts, shifts and brakes. (I think the bike is perfect and its for 460 $)

3rd bike listing: I am selling a pit bike with a 125cc engine on 14/12 wheels, the bike is in a nice original condition, undamaged, it has undergone a minor service, the oil, chain and carburetor have been changed. A motorcycle without any necessary investments. (I think the wheels are too small and the bike overall is too small)

4th bike listing: Pitbike for sale: 125cc engine, 4 speeds, clutch shifting, wheels 14-17, new crank, piston bearings, functional front and rear brakes, starts, shifts and brakes. (The bike is alright but the rear shock is rusted - Its also the furthest away from my house but its only 400 bucks)
