If you have never ridden before, the class is a great idea.
Back in my college days I had a pal with an unassuming little Suzuki 250 that we would take to a big parking lots and I took my time and learned to ride that way.
A few months later a bought a Kawasaki 600 and rode it for a year and about 10,000 miles and really got my education out in the hill country.
Riding through rain, slippery water crossings and tight corners all had to be done, so you KNOW what it feels like and gain confidence in all situations.
I sold the 600 to a friend and moved up to a Honda '96 VFR 750 because I wanted to start sport touring and taking trips out of the state.
Before doing so, I finally took the MSF class to stop being an outlaw and get my license. I remember how much fun it was because they have you on small, un-intimidating bikes and made you lock up the brakes and do some fun drills, etc.
Can't go wrong taking the class and good luck, be careful out there.
And you might just have a lifelong new hobby!
