I love my Super Duke, But....
Geese, that thing goes thru gas and tires. I usually get about 35 mpg. A Pilot Power 2 goes about 2600 miles before the cords show.
I can dog it, and it has done as well as 45 mpg.
I'm rethinking my tire choice. I doubt that I need such a soft rear tire. I have gotten good at changing the rear tire, tho. In about 20 minutes, I have the rear wheel back on, and am adjusting the chain slack.
