Hi All,

My local dealer has some tubes and says they will be fine - but figured I would ask here - on my KTM 200 EXC the tires sizes are as follows:

Front is 90/90-21 - can I use a 80/100-21 tube with no issues?

Rear is 110/100-18 - can I use a 120/100-18 tube with no issues?

TIA

Yes, they will work. I had to run a 21" tube in a 20" tire and it worked fine..............

That should be good advice judging by your screen name!

Thanks!

Hey MXEditor,

Those tubes will work just fine. I currently run the 90/90x21 front tire with a 80/100x21 tube and same with the rear 120 tire with a 110 tube. You will be fine man. Run it and have fun

True, I always have a 21 tube in my back pack and have had to use in the rear tire and works just fine to get back to civilization.

Maybe I will just keep a 21" tube as a spare for either!
