ok so i bought my son a 2018 kx85 last September because he out grew his 65. over the winter the kid must have grew a foot because he's to big for the 85 now. i have all the clickers turned in and hes still bottoming out. he's 12 years old 5'5 125lbs. My question is should i do a big wheel conversion and get a taller seat or get him a kx100? Is it worth the time and money to do the suspension and all the work on an 85 or just get him the 100? The only thing is he's not using all the motor of the 85 yet, its just hes to big for it. Not sure how much more power the 100 has.He's getting faster and faster but the suspension is holding him back. hes not comfortable landing long jumps but he knows he can make them. just wondering if anyone has run through this. any advice would be greatly appreciated. thank you

I also did the 85 to supermini mod. It's really not worth it unless you just like building bikes like me lol!!
For a 125 5foot 5 is a little short but you could have the suspension shortened and back to normal after he grows a couple inches more.
IMO on the 85 I would look into taller handlebars and getting the suspension done and get ready for a 125 or 250F next year.

Nothing here even remotely suggests he needs a 125 as others have suggested, plus he might have a hard time touching the ground. also, if he is a beginner level rider, a 125 can be a quick way to send him to the hospital.
He will likely never, ever, be able to use all the power any high perf bikle has, if he could, he would be a national champion.
I would buy a used 100.
It already has the longer swing arm with big wheels. New springs and revalve, I will let you know how it turns out.
I am looking for a KX 100 frame 14 and up, lmk if anyone has one for sale.
Thanks
Not gonna happen.

if some one is parting an 100 i would want to know why, i have bought used frames and turns out they are cracked.
i would say just be careful.\
why not buy an 14 plus 100 and take the motor out of the 85, and part the rest of the 85
You can easily tell them apart at the track, just by looking at the gas tank bolt location.
Cracked frame is not a big deal, we can fix that no problem!
