It follows, slow speed riding a two-wheel motorcycle can be difficult; so, the bike wants to fall over and rest on its side. That is not the intent of keeping two-wheels down and bike under controlled riding at slow speed. There exists a number of great riding instruction articles available; for example, see generally, Slow Speed Maneuvers – Back to Basics, (good pointers to keep in-in-mind while riding along) http://www.ridemyown.com/articles/riding/BTB-slowspeed.shtml (last visited Feb 1, 2016)
How it’s done
I think this, three concepts that contribute to the motorcycle desire to fall-over and rest on the ground: 1) the motorcycle upper parts and weight must always be over the lower wheels for supporting the bike upright; 2) motorcycle handlebars control the direction front wheel is pointed and the direction front wheel travels toward, so front wheel pointed direction and speed of motorcycle will determine how slow- or how-fast the front wheel can relocate its position underneath the upper bike frame and support the bike weight balanced; 3) as a result, as the upper part of the bike leans over, to stop the lean, point the front tire in the leaning direction and all enough bike speed to move the front tire under the upper part of the leaned bike; as a result, the leaning bike lean will be slowed then stopped.
Also, be careful with both steering and throttle control inputs because with the bike leaning towards one direction but over applied steering or twists-of-the-wrist (throttle) control might cause the bike to lean towards the other side or just not move the front wheel under the upper part of the bike fast enough to compensate for the speed of the bike lean and its fall over. Therefore, practice “throttle” and “handlebars” controls until this is engrained into your unconcise physical control reactions.
Where to practice
Specifically, all your motorcycle practices must be done in large open hard surfaced parking lots or areas, free of cars and other obstructions, and wearing your best fall-protection garments and helmet because falls of bike and rider is likely while learning.
Two-wheel vehicle driver operation (the rider) and twisting-the-wrist speed control is a most important riding control ability while riding along; as a result, just to keep the front tire under the upper part of the bike frame–necessary to prevent the bike continuing its falling-over and resting on the ground–the rider must have the front tire pointed towards the direction of the leaning bike, while moving ahead, and with enough speed added with wrist-twist speed control to track the front tire under the leaning bike quickly enough to lift, or just maintain the desired bike lean angle, and to pick the bike up out of its leaning or falling-over direction.
Therefore, the bike rider is controlling the bike from falling over more, towards the leaned over side, because front tire tracking under the leaning bike at a speed quicker than the falling-over frame falling down speed–front tire moving more quickly under the bike and with a rider controlled forward speed–so front tire tracking is returning-to-upright that is counteracting the bike leaning or falling over direction and falling over speed.
To make all this lean control happen the rider must control the bike forward speed (twist-of-the-wrist) as it is leaned and pushed (rear tire and engine power) along in the direction of the front tire pointed underneath the upper part of bike frame.
And just some other things rider must always consider:
The speed of the upper part of bike leaning or falling over increases as the lean is increased;
overdoing the speed and time of tracking front wheel out of a lean can be overdone–for example, cause the bike to stand up and start to fall in the opposite direction as the front wheel is driven out from underside of upper part of bike frame. Be cautious. Be in control always;
bike front tire suspension is usually designed such that at stopped for real-slow speed as bars are turned to stops the bike would like to fall over the front tire towards the tire pointed direction;
for a bike to turn it must lean in the direction of the turn;
on-throttle or off-throttle (twisting-the-wrist) similar to increasing forward tracking speed or adding rear brake by engine braking; and
counter-steering is just a method to get the bike leaned first for turn.
The bike rear tire sliding sideways as bike not moving forward from stop. Just rear tire slipping sideways because of lost tire traction.
My learning and thinking is now this, related to sliding sideways rear tire while attempting to move forward.
I now have three methods to leave this grass curb parking location under rider control:
Push the bike forward so rear tire off the grass for good road traction with street tires;
Lock on the front brake, point the bike bars straight ahead, and let the rear tire burn down to tractable road grip surface for going forward; and
Maintain the bars so front tire is aligned with center line of rear tire, let the bike rears move to the right or left, but at all times keep that front tire aligned with rear tire center line; as a result, when rear tire gets road traction the front tire will let the bike move the direction front tire is pointed and not drive or push the upper bike frame over towards the side direction that front tire is pointed.
Wet grass and starting forward from stop just don’t mix well for keeping the ‘rubber-side-down’.
Best suggestion I received: “Don’t ride it out.” Get some tractable surface for that rear wheel to grip.
Spring appears to have sprung here already; therefore, it is now good scooter riding weather, but still dress for the potential of accidental crash or meeting mother-pavement if the rubber side does not say down.
