2011 250f big bore?

Recommended Posts

Hopefully I am not reposting here, but has anyone installed a big bore on the 2011 KX250F?

I run the 40+ class and don't want another 450. I really love the 250 but would like a little more bottom end grunt. I'm aware that I will probably lose a little over rev, but I'm not really up there much any way!

Thanks in advance,

HR

I HAVENT heard of any on the 11 fuel injected yet, but i did one on a 09 for a friend. with stage 1 cams it was a cylinder works 270 kit, the cam dictated where the power was not so much the bore. 270 is perfect for not changing it that much. his bike with the cams and fmf pipe has a lot of touque of the bottom the front lifts easy with no wheel spin, kind of feels like a heavier fly wheel. hot cams has a new stage2 cam for the 11, that would be nice with the 270 kit. plus i like yosh pipes they work good. that would be a nice set up.
