Before I got my M1 last summer I had ridden a dirt bike on a farm maybe 2 times. That was the extent of my experience on a bike.

Last June I went for my M1 and took a training course at the local college. By July 5 I had purchased a 2003 Yamaha YZF R6. I am 31 years old have had 2 speeding tickets, both when I was 17. Not saying I don't speed I do. But I am afraid of losing my lisence and my insurance rates going through the roof. If I want to top the bike out there is lots of tracks close by.

I have not read the whole thread but I am sure it has been said if your mature enough and smart enough to know what a bike is capable of regardless of the size and have respect for yourself and others on the road, you can get on any size bike.

In saying that my neighbor a little younger then me bought a 2007 yamaha YZF R6 and he is one that shouldn't even be on a 125 least of all a 600. Just my opinion but the maturity level of a person dictates what they can and should drive.
