Racing is Hard on Equipment

     It's not a saw blade, it is what's left of a rear sprocket on a strutted Sportster after a hard run across the country. 

     I first noticed extreme chain and sprocket wear during Stampede 9, when my Sportster was strutted. 
     I wrote about that unusual wear in my "belt vs Chain" post (click on the label below).

     I think that there is something about a strutted Sportster that causes heavy chain and sprocket wear. Perhaps it is the lack of any "cush drive", like we see in many other chain driven motorcycles. 

     Gordon Porritt (#4) finished 33rd despite the extreme chain and sprocket wear.
