Like Clay said.. You’re not going to forget what you learned in the MSF if you can’t buy a bike right away.. Just remember when you finally do get a bike to take it easy and start with the basics on it.. Get used to the feel of it and how it handles before hopping out into traffic..
I bought my bike before I took the BRC.. Mostly because I got a great deal on it and didn’t want to pass it up.. I had also ridden as a kid so I wasn’t coming into it completely new.. For anyone coming in never having ridden before I think it’s best to wait and buy a bike after your class.. A lot of people get in there and realize that riding just isn’t for them.. And even though it makes for great deals on bikes for the rest of us (Buying bikes from people who decided they don’t like to ride that is..), it’s a better deal for you to wait.
