im 13, 5,7 and l weigh around 135 pounds. l trail ride and ocationally go to the track. most my buddies have 250fs and l need a bike that can keep up with them because l cant afford one. l know the 230 is built like a tank, but what about the durability of the 150r? and how long would it be before it needed a top end rebuild? because thats like $1000.

first off it doesnt cost like $1000 to rebuild the top end, on a yz 125 its about $90.

but if u want to minimize the chances of ur top end fallin apart clean ur air filter all the time then spray it down with a lubrication, l forget the name but it makes it so ur filter sucks less dirt & more air. when u get ur top rebuilt they basicly give u new o-rings


but l would recomend a yamaha. They have more rip than a honda. but if u dont like yamaha get a kawasaki, they tear the dirt up & r super easy to handle.

yamaha- wr 250 or ttr 230
kawasaki- 250f or 250
ktm- ktm 144

well im only 5'5'' and ride a 250 fourstroke and love it, if thats what ur buddies have i'ld say you should go for that one, but a 250 is a much bigger bike and a lot heavier make sure you can handle it before purchasing one, maybe ask your friends if they will let you ride it to see if you like it

l am 5 9 14 years old and ride a KX 250 2 stroke and its not to much for me They are both pretty slow bikes so you should get the faster 230
