Carl, I cut and pasted your discription and came up with the tire.
I don’t know why but I could not find that tire previouskly.
The pattern on that one is fine. The pattern on the tires I had found were large block style, similar to small knobbies for off road racing.
Thanks for the direction. I’ll need to get a pair of these.
Question about the shifter on the two speed, do you need to hold the lever in 1st and then release for 2nd?
Also, what can be expected for speed on one of these as a stock machine?
I haven’t counted yet but I seem to have quite a large rear sprocket. Were the Sports used for dirt tracks?
