I currently have around 40 hours on my yz250f and have been reading about a lot of people having issues with bottom end components failing at low hours on this 2016 as well as the 2014 and 2015 models. Just wondering if this is something I should be concerned about and if anybody has any clarification on the matter that would be cool as well. Also noticed specifically for the 2016 model, you cant find hardly any bottom end kits other than obviously OEM parts online for the 2016 yz50f, but there is a bunch for all previous and newer models.

I believe it's the 14 and 15's that had crank issues... and the 16 got an updated crank/rod. I could be wrong though.
If I'm right the crank in that 16 is a very good unit.

There was a water pump issue if i remember correctly on the 2014. It got fixed for 2015. As far as i know....you are good and have one of the most reliable bikes made. My 2014 held up great and is still running at the hands of the 4th owner.

I'd check the headtube for cracks

- crank should be fine.

Only issue I had in 150 hours was the frame crack which they warrantied. Piston at 65 and rebuilt at 120. Only rebuilt cause I planned on keeping it long.

That is correct.
I had a 2015 with 80 h and did nothing to the engine other than changing oil. No problems.
I wouldn‘t worry about the reliability of a 16 as long as you keep changing oil and air filters.

I think we had 3-4 kxf250s, one was a 14' and we put 60 hours on it before we sold it and we did nothing to it. I think we had 3 of the 16s, my son averaged 100hrs on each of them except one, we lost in a flood and it had 20-30 hours on it.

We literally didn't do a top end or anything to them until around 90 hours on them.
I wish we would have stayed with Kawasaki but we switched to an 18' Honda 250f when they redid the bike and it was a complete disaster. Many manufacturing flaws, I ran literally 2 gallons of fuel through it and the engine locked up.
That was a fiasco with Honda pretending they didn't know anything about it. Still have a brand new honda just sitting there. Doesn't run. Just sits there

Umm question, what does the Kawi or Honda have to do with OP original question? Not being a dick.

I had valve issues with my 16 and 17. Nothing in the bottom end. 60+ hours on the 16 and 45+ on the 17.

Have two Yamahas now and they are good.

My friend who is Vet 35+ did 150 hours on stock piston and bottom end.

Depends how you ride and maintain it.

We have a 15 with 170+ hours on it. I have a 16 we put a topend in at 42hrs. Everything looked great!

As said above the 14 & 15 had the bottom end problems...

If you do a bottom end do yourself a favor and go OEM or have the crank sent off. Don't go aftermarket...
