I've been riding for about three weeks now. Passed the safety course and bought a SV650S. Practiced in Suburban Boston for three weeks and then got on the highway for the first time. I have to admit, I was horrified. Even though I have the small fairing with windshield, I felt like I was going to be blown off my bike at 65. Meanwhile, a guy passes me with a large woman on the back of his bike doing about 80 and holding on with one hand. Within 5 minutes I lost all circulation to my right hand. I suspect that I was probably holding on too tight out of fear as I don't lose circulation driving through my neighborhood. On the return trip I cramped up in about 5 minutes as well and had to pull over to get feeling back in my right hand. Is numbness like this common? Am I overreacting to the sensation that I will be blown off backwards. I wasn't tucked in behind the windshield, just leaning forward a bit. I'm not going back on the highway until I get more practice.
