Having trouble finding a rear inner tube for my 630. I have a Michelin tube that fits 110/100/18 100/100/18 or 130/80/18 is it ok to run it???
Yes. No problem running the 130 or even A 120. I have used 21 inch tubes in 18 in rear wheels in a pinch, no problems.
I am a Motoz dealer but am out of stock on stuff right now. I would try Braap offroad. http://www.brapoffroad.com/motoz/
