Which is the best bike for Karting track ?

[guigui404]

Hello guys !
I've a project, I wanna buy a small bike, maybe 125CBR or RS50, to be able to ride way more and improve my riding position and other things.
I think I would spend max 1000€ to buy this training bike.
Wanna have the advice of some of you about which bike, pros and cons, etc

Thanks for reading

For kart track? Do they let you ride with the bikes you mentioned? Tbh I would search for a MiniGP, but with a budget of 1000, I think it's hard

Yes you can usually ride with small bikes on karting track so rs50 easily, and 125cbr too, I used to ride a 250r ninja on a karting track
