Motorcycle/bicycle riding should be the same way. Instructions are OK, but the focus should be on learning by doing it.
I have 35 years experience riding bicycles on paved roads and bumpy dirt roads.
My bicycle is lighter than I am. A motorcycle is usually heavier than the rider, so motorcycle riding probably feels different and my skills might not be applicable for motorcycle riding.
Counter-steering is important. Now it's like a reflex. Sometimes I swerve to avoid a rock and notice myself counter-steering without even thinking about it.
My first mountain bike had no suspension. It was a good learning experience. It taught me to flex my arms over bumps and avoid "Stiff arms".
My comment about swerving to avoid rocks might not apply to motorcycle riding.
1. Physics of steering is negative camber thrust, combined with the differences in angle between the front and rear tires in a turn. The rear tire wants to continue more in the momentary forward direction while the front tire is heading into a different direction. Motorcycle physics is governed by forces like gyroscopic stability, which keeps the bike upright at speed, and counter-steering, where a brief push on the handlebars in one direction initiates a lean in the opposite direction. Cornering involves a delicate balance between centripetal force (the inward force from the tires' grip) and the torque created by the bike's lean angle. Other critical principles include traction limits, which are determined by friction, and the management of weight transfer during braking, acceleration, and cornering, which is heavily influenced by the suspension system.
2. Tires are rounded to maintain constant-sized contact patch with the road surface. A rounded shape ensures the tire maintains a nearly constant area of contact with the road, regardless of the lean angle, which is crucial for steering and stability. If tires were flat, the contact patch would decrease dramatically during a turn, leading to a loss of traction.
3. 3-wheel Trikes (2 rear variety) are completely different, and can be dangerous in curves ... go too fast, and you will tump forward to the curve outside (like Artie Shaw in Laugh In ) and do a devastating high-side fall, with the trike on top of you.
I know nothing of the characteristics of the Can-Am front trikes. Probably more stable than the rear-wheel variety. I personally am not a fan of either of these machines, but if and when I am no longer comfortable on a 2-wheeler, my BMW K1600GTL can be converted to a sleek-looking trike for about $10K.
4. 2-wheelers are far more fun than 3- and 4-wheelers.
