That depends on bike and rider experience and driving experience. I got a quote through Progressive as a brand spanking new rider. Bikes that were under 500cc's seemed to range about 25-50 a month, I believe I did full coverage. Over 550cc's tended to range to about 3-4 times that amount. And yes that is another reason why it is good to go with a slower bike as a newbie.
Main thing your not me, your quote might be different, try going to
www.progressive.com try a couple different bikes see what you get.
