Welcome!
http://www.trackaddix.com/ should have the information you need to get signed up for a track day at MAM. Also we have a sticky in racing and trackdays with a lot of that information.
What is everyones big deal with starting on a liter bike, my wife learned how to ride on mine from no experience at all. Its not the size of the bike its the idiot that's in well was in control if they don't respect what there doing. Hell I had a 600HP 64 chevy 2 Nova when I was 17 an that was no big thing?
So I say more power to him for learning on a liter bike just goes to show it can be done more over then people stereotype.
Rant Over!
While it can be a case between rider's respect for the bike and not a skill issue, in most situations a newer rider will be much safer on a smaller bike.
On any literbike i've ever ridden there was not a whole lot of margin for error. It takes some pretty precise throttle control to put the right amount of power to the ground while doing certain maneuvers on a bike (emergency situations, and all that) that if you're inexperienced and apply too much or not enough and try to adjust too quickly you can find yourself in the hospital.
Can riders begin with literbikes? Yea. Should they? not usually.
If i could do it all over again, i wouldn't.
