Hi Fellas, I have been inundated with request as to whether these boots will work on Bonanzas, Broncs, etc, etc. My boots are exact reproductions of the ones used on the Fox Campus minibike. Because I am not familiar with the dimensions of any of these other bikes; I've decided to post the dimensions here and you can be the judge as to whether they will work on your bikes or not. The overall length is 4-1/4 inches. The inner diameter of the top and bottom holes is 1 inch. The area where the clamping bands are placed on the top and bottom of the boot is 5/8 inch each. I hope this helps. Ogy
