If they're doin' it right, they'll include, but not be limited to, the following:
1) Safety in gear, in bike, in riding and in traffic.
2) Defensive/Awareness driving techniques and concepts.
3) Motorcycle anatomy (mostly the controls of the bike)
4) How to mount and dismount safely.
5) How to start the bike safely.
6) How to stop the bike safely.
7) Throttle, Brake and Clutch control.
8) Low speed exercises and maneuvers. Speeds rarely exceed 20 mph and are usually lower. Exercises include:
Laps: Just to get comfortable with riding in general.
Slalom/weave
Braking
Shifting
Low speed figure 8's
Low speed u-turns
Slow Ride (straight line riding as slow as possible)
Countersteering/Emergency Countersteering
The last BRCII that I attended here in MD in 2006, they also covered facts on drinking and driving, including MD state law and penalties and they also covered MD state helmet laws.
Bottom line, go there to have fun and you can't help but learn. If you ride at all already, some of it may be old hat to ya, but you'll probably also find some alternative/better ways to do some things.
TIP: Bring PLENTY of water to drink (they may provide, but just in case, bring your own) and, if you're prone to sunburn, bring plenty of sunblock!
My compliments on being smart and taking the course. You'll be more informed, better trained and much safer for your trouble.
Have fun!
