2014 KTM250EXC-F rear tyre size?

[chadsta]

Have any of you had any experience running the Pirelli Scorpion XC Mid Soft 120/100-18 on a 250F?

This is my wifes bike and she is still learning, wondering if she is not better off with the 110 rather than the 120?
I'm busy fitting the 120 on my 300EXC but I have a lot more seat time and my bike puts a lot of power down.
What are the pros and cons of the 110 vs the 120 other than the 120 having a bigger footprint and the 110 being better in the ruts.
I'm leaning towards the 110 because it will be lighter and easier for her to handle, probably still have great traction too.

I've got the 110 xc mid soft on my 250 2 stroke and have been more than happy with it. Riverhead and Woodhill (mud and sand) mainly. Done 50 hours with nearly half of that racing , turned once. No knobs are missing and it still looks good, try that with a S12. I will replace it with another.
I think a 120 is too much tyre for a 250f.

a 110 is plenty of rear tyre for a 250 4t, it will turn in easier than a 120 as on the same rim size the 120 has a flatter profile,

Thanks, was thinking the same thing.
Will get the 110 and maybe even consider it for my 300 if I find it hooks up and turns better than the 120.

Use a 110 on both a 120 is more suited to 450/505/520's etc , just don't be confused by Michelin's sizing they measure there's differently to everyone else, must be a French thing.
