Tire width

[Lrat4]

I have a 2005 kx125 with stock rear tire size of 100/90x19. My question is what is widest tire size that will fit? I race/ride mostly woods. I have a crf250x with a 100 mm rear tire, but the tire on that bike seems much wider.

Any help will be appreciated.

Stick with the stock size, you'll find the bike will have a harder time turning the wider tire.

Wasn't sure if I wanted to try a wider tire or not. I know I couldn't go much wider.

Thanks for your input.
