The only things I can think of as intermediate courses would be:
1. The MSF ERC course. But that’s geared towards those that have at least 1 years riding experience.
2. Novice track day.
The free things would be to find a parking lot and practice. The MSF BRC hasn’t changed at all in many a moon, so you can take what you learned at the MSF BRC and apply it to the parking lot. Another thing is to network. Find a motorcyclist forum in your area and join some rides or ask a local to mentor you. The other free thing to do is to just go out and brave the traffic on your own… You can’t get the best out of your bike or experience if you don’t ride it.
If you haven’t already done so, grab David Hough’s Proficient Motorcycling book. The MSF bases its course curriculum around this book anyways.
G’luck and happy motoring.
If there’s anything more important than my ego
around, I want it caught and shot now…
