BTW-Your leaning the bike, would be your first crash.
It wasn't my intent for us to thumb our noses and say look at you, you don't know what you're talking about, but.....it kinda did illustrate that point, and being relevant to your question of are they hard to ride.
Any bike is hard to ride. There is a specific motor skill set you develop, and habits. Granted, I didn't describe terrain surrounding the curve, visibility, and other related items. However, there is far more involved than just leaning the bike over.
Skills and habits such as slowing before the corner, looking as far through the corner/curve as you can with your head up, choosing a delayed apex, a line through the corner that allows you to go outside/inside/outside, choosing a line that gives you maximum control of the bike, and room for errors or environmental circumstances that pop up.
Pushing the steering controls in the opposite direction of the turn. Rolling on the throttle to settle the chassis. Looking through the turn to where you want to be.
Just a whole bunch of skills that we would hope you pick up by taking a $200 class, and maybe a bike that won't constantly tax your limits and abilities. One that is forgiving and a pleasure to ride.
