I applaud your good common sense being a new rider!
I started on a Honda mini trail (mini bike) when I was..errr...11 or so...been going at it ever since.
I also am a former Motorcycle Safety Foundation instructor many moons ago when in the service.
Even so, I have taken MSF courses since, as a student, skills to ride have to be continually honed. You never stop learning and developing skills.
The BIGGEST THING...don't exceed your skills...at the cuurrent state (of riding experience) you are in...you are always building on them but starting out..get the fundamentals down pat.
THEN you can start moving ahead.
My grandson got his first bike...my advice when people ask...start small, learn in the dirt and THEN move up.
I have been witness to folks want to ride and buy HUGE powerful motorcycles and have no clue how to shift, corner, brake, counter steer, etc...they get the ginormous bike and get in way over their skill set.
Sometimes to a sad end. Or wreck it and blame the bike.
Take those basic classes to get your lisc. then follow up with advanced classes.
Videos can be useful sure, I like to read, I like motorcycles, so I read the books on methods (riding), safety stuff, all that...but each time you are riding, you are learning.
Try this, I do it often...say you go on a ride to a local state park or wherever, make a mental not of anything that felt "off" or "was not right"...I strive for a perfect ride (meaning me, braking correctly, no missed shifts, cornering , etc.)...if I have something happen..like a car or whatever cut me off...I try to recall WHY that happened...of course, the car driver did something stupid..did he not see me? If so, was I in a blind spot, was the sun in his eyes....try to pin point why and how to avoid in the future...
Ride safe, have fun, if it isn't fun, why would we do it?
I highly recommend this book, many are out there and this is a great one....I got mine off Jeff Rocket man web site if I recall...
