Leftyno1 Posted October 11, 2015 Share Posted October 11, 2015 Hi just checking on the inner tube size for the rear tyre on my DT 125 R . the old one I took out was a CST 3.25/3.50-18 tube and the new one from Yamaha is a Bridgestone 4.10-18 tube .The tyre fitted is a Mithchelin Enduro 140-80-18 tyre.Asking because new tubes valve seems to stick through more as when tyou tighten the 2 nuts up there is visible rubber showing, not right i am thinking.Cheers.
