Lostonwheels, Are you using a tube in the TKC80 120/90-17 rear tire on front? I see where some say it can be run tubeless? Thanks
Sorry for two years late.....
Yes I am/was running a tube on the 120/90-17. Don't know if they've changed, but when I got it the 120/90 required a tube where the smaller sizes didn't. Apparently you "can" run them without a tube but there is a risk of delaminating the tread so... I wouldn't
I use some beefy 4mm tube that has never given me problems. I think it was a moose racing tube.
