Hi guys, I recently purchased a 126 a serial number 0 0 6 it has been stored for a very long time and probably has the original Tire still on it I am looking for a 4.00 / 4.80 -4 tire and tube. Ive tried the 126 News Group with no luck they won't approve my listing yet it's been a couple of weeks so I thought I would try here.

No longer available.
Replace with 4.00-4. Desser has it. Flatter "ribbed" profile works better for brake. You will have to rework the brake band due to slightly larger diameter.
Good luck
