I am trying to understand the following image:

Could someone please help me understnding it. What I understood so far: Your angular velocity mutyplied by the impulse gives you the impulsemoment. By applying the right hand rule, you know the impulsemoment-vector is oriented to the left.
When you lean to the left the normal force and gravity force combined create a torque which is a pure moment. The vector of this moment is oriented to the rear of the bike (applied the right hand rule).
I think -and hope- so far my explanation is correct. However when I apply it to a real situation it gives quite strange results:
on the first image it seems even as if you go backwards and turn to the left, in stead of going straigh forward and turning to the left. And the second image yhea... seems completely proposturous
