How to start MX..?

A 125 will be less expensive, easier to maintain, and you can join the others and me in the 2-Stroke Taliban when we say:

"Two strokes truck, four strokes suck!" 

125 allll day!

2019 or newer rmz250. 4-5k will get you one like new. Search your area , send the ones your considering on here and I’ll let you know which one I’d consider.

id want one with 10hrs or less that looks essentially new, all oem parts, no wear etc.

a 125 is cool and a ton of fun,  but a 250f for todays tracks will let you get around the track a lot easier.  125s can be challenging when you’re not only learning how to use the bike but also learning the tracks, and taking it all in.

250f makes learning the bike easier so you can focus on the track and yourself a bit more.

I highly recommend scrapping the motocross idea and getting a CT110 with an ice chest mounted to the rack instead.
