19th practice to ride python

Riding 20 km/h is better for me. this time's max speed was 31.5 km/h, then I felt down because I lost control of handling.

 It's dangerous to ride with max speed for me. stable riding is needed for me to ride in public road.

about 22 km/h. it's better speed. I can take back control of handling when I lost it.
Fine.
