A novice perspective.
Lots of excellent advice and I appreciate that you have taken the time to put it in print.
As a new rider I have been seeking out as much advice as possible and I have found youtube to be vary helpful.
First off " Twist of the Wrist" is in video form, at least part of it. A little corny, as its dated a bit, but the information is excellent!
Although limited, you can find some footage on current driving courses in the states to see what is being taught, then go out and practice the skills.
I found the european, England Police I believe, do extensive on the bike testing with new riders. You can watch from behind, trailing the rider being tested, as the instructor evaluate their performance. Lots of excellent advice and tips!
The basic of basic skills to master:
Stops and Starts:
As a new rider I just road around for a couple of days concentrating on my stops and starts. I did have riding experience, but it was back in the day of mostly right sided shifters.
It only made sense that my left foot would support the bike at stops, allowing me to use the right foot to brake. I also found it was important to use the rear brake over the front brake, at slow speed, as the front brake at slow speed encourages the bike to tip. By slow speed I am talking under 5mph.
Of course you will need to become proficient in placing your left foot down as well, and practice using the front brake to hold and some throttle as you take off from a hill.
In addition you need to figure when to downshift to 1st gear at a stop and when to drop it in neutral. First gear is great for quick stops, neutral for longer intervals. In the event you chose neutral you may find the right foot down a better choice.
Like I said these are the most basic of skills but they need to be mastered.
