To kind of recap, I am a new rider (and I love it) of about 3 months and since changing from a Sportster to my Heritage Classic I have finally gotten comfortable riding at faster speeds, like 70 MPH. I was supprised at the effects of air turbulence from traffic. A vehicle in front of you produces a wake effect. And traffic going the opposite direction at high speed produces turbulence that you have to be ready for. I got brave enough to get on the Interstate and was amazed at the effects of 18 wheelers. The first time, I thought I was going to get blown off the road. Is this something that you just get used to? Are there any hints/rules on dealing with this? You veteran bikers are a great help for new riders like me and I appreciate your comments!!!
