The motorcycle was my first vehicle; 250 Yamaha where I learned to ride from a friend who had a Honda 350-4 I think (my second was a 360).
Got my license in fall of 76. Test was in Fredericksburg at the DMV. Start the bike. Turn signals, brake, headlight, horn. Go to the end of the parking lot, loop around, come back. Stop here.
You passed, here's your endorsement.
The Army required the Defensive Drivers Course before you could ride on base. A much better class. Pretty close to the ERC I took a couple of years back. Emergency stops, pay attention to traffic, here's a bunch of pictures of motorcycle accidents (he was a Md Highway Patrolman). Saved my ass at least twice by realizing the guy making the turn didn't see me and my realizing it and stopping before it went south.
I don't think I learned much more until a friend talked to me after getting back on a bike about the 6 seriously close calls and numerous ones. After that I've read and applied proficient motorcycling, read several track books, total control which was quite interesting, been to the track several times, performed most maintenance tasks (I never touched an engine leaving it to Jiffy Lube Me Up until I got on bikes). I've put 125,000 miles on the Hayabusa and another 20k or so on different bikes.
I'm no expert, but I do explore and have experience. I am better
