Optimum Inner tubes for non-standard scooter tires By papat (Read 232 times)

I am customizing a CT70 (125cc) clone and am currently ready to assemble my chosen tire/wheel options. I am using a 130/70-10 Zippy on the back and a 120/70-10 Zippy on the front both with G-Craft 4.0 Stainless rims.  I have contacted at least 8 scooter tire dealers to buy the correct tubes (wheel Supplier advised that G-Craft Rims require tubes) but no one has a clue and finding a 4.0-10 high speed tube still eludes me.  

Does anyone out there have experience with this situation?   The bike will surpass 60 mph when complete and I want to have the safest tire/tube arrangement going in to the corner.  Your help will be very much appreciated.

Finding the exact "size" may be a chore,,,if not impossible but the tubes do stretch and one size under is not an issue,,,make sure you talc them good so they don't get hot,,,it's the tire that contains the tube so tire rating is much more important,,,,a good quality tube is all that's needed,,,and mostly for balance reasons than anything else
