Question

i see yamaha will make the 09 250, how big of a boring kid can i put in and is it pricey

Answer 1

?

Answer 2

If you need more power than the stock YZ250 makes you're more of a man than me. Excellent bike though!! I think the 2 stroke 250 will be around for a while, the 125...that's another story.

Answer 3

There is one site that has big bore kits to make the YZ250 into a 265 or you can buy replacement pistons that increase the bore by 2mm.
