Yes the motorcycle safety course is for 2 wheels (at least it is here in CT) but it is PRICELESS for what you learn. Just cuz you're not on 2 wheels doesn't matter, IMHO. This course teaches you do deal with panic situations - and since you are in an "open air" vehicle, no seat belt, no airbags, no metal frame surrounding you, I think it's a good idea to take the course. Teaches you how to deal w/ emergency situations, whether it be a panic stop for a deer, a stupid soccer mom on the cell phone, kids darting out in the street after a ball, stupid pedestrians, everything and anything.
I took the course and it was what I needed, plus I got a small break on insurance as well. I took this course and rode two wheels - I apply all the same stuff (except for leaning) when ryding my :spyder:.
