I am wondering why people who talk about bikes that are 1200 cc and less, talk of them as beginners' bikes. What size is an experienced rider's bike? I have a 650 cc. I'm 71 years old and 5'5". My bike is the same size as a Road King. My bike easily gets to the maximum speed limit....probably just as easy as any other bike on the market. If my bike falls, I am pretty certain to be able to pick it up. I'm pretty sure that I won't get all hot and sweaty riding in downtown traffic. I know that a motorcycle is a phallic symbol but I'm surprised at how many people boost their sexual persona with huge motorcycles.
