Been riding street bikes 17 years and just got bit a couple of hours ago on my way home. Damn sand that had been washed out into the turn from last night's heavy rain. Blended in with the concrete portion of the turn/exit and didn't see it 'till it was all over. Not too much damage thanks to the frame and swingarm sliders (broke one), a little paint missing on the tail section and a scrape on the clutch lever. The left case cover got most of the grind though. Fortunately not enough to leak.
Best part of my ordeal-My riding gear saved my butt from a worse fate. I can only imagine if I were one of the idiots I see on campus in flip flops and shorts on sportbikes.
I have always ridden with protective gear, especially a jacket and gloves. Consider this a testament as both (jacket and gloves) suffered serious setbacks from the road surface, but not my skin!
