Anyone else get "itchy a** syndrome" when riding at highway speeds? Kind of like what a cheap chainsaw or lawnmower does to your hands. My M50 gave it to me bad at 70mph, and even the 1600 gives me a case of the itchy butt (but not as bad) from the vibration at highway speeds after a short time. Is it the stock seats? Could it be the make up of my butt? A combo platter of both? I'd love to get out on the open road this Spring and maybe take a couple of good long road trips, but if I'm going to have my butt itch until it goes numb, then that plan may be on hold. Just wanted to see if anyone else got it like I do. Maybe my rear nerves just need to get a callous worn on them from riding.
