Okay, I am usually pretty meticulous in my maintainence of my motorcycles. But apparently I overlooked one tiny little detail on my KTM. Today, while descending Ophir Pass, I downshifted from 3rd to 2nd and all heck broke loose. Actually, it was my rear tire that broke loose. The rear wheel locked up, and I had a few stressful seconds bringing my ride to a stop without dumping it over the edge. I inspected the bike and found that the counter sprocket had come off, then lodged between the frame and swingarm. So, I broke the chain, wrapped it up out of the way, then coasted down to the highway to wait for a ride home. SUCK! So check those bolts!
