I got my M1 almost 2 years ago.
And I don't think I'll ever quit.
Just went to Borders today and picked up a copy of "Proficient Motorcycling." I'm not nearly done yet but it's really good, I would recommend it to other n00bs as a highly educational read.
Was waiting for some more noobs to respond in hopes that somebody would have been riding less than the 2-3 months I've been riding, but oh well.. Got about 300 miles under my belt so far, hope to be riding for a long time.
