How do I know for sure that this 145x70-6 tube will fit the front of my 1987 yfm 100 champ that says 18x7-7?
Not sure of the conversion of tube size.
Need a tube for the front of the bike listed below.

Unfortunately this tube will not your YFM100. The wheel size is incorrect as this tube would be for a 6" wheel and you have a a 7" wheel. In addition, none of our vendors make a tube in the correct size for this model. You may be able to install a tube that is not the correct size and it may be able to work, but it is not recommended.
