The ideal racing line! I wouldn't be doing that anywhere on corners on a road. How do you see what coming from the opposite direction. Because the racing line would be making the corner as straight as possible....therefore cutting the corner on the opposite side of the road!
Whether in Europe or Thailand I would advise that you ride so the apex of the corners you are riding around are opening up quicker so you have a faster and better visibility on exit because visibility is paramount, especially over here. So on a right hand corner keep it to the left, in the 1 third area, so the corner opens up quicker, hence more visibility. Left hand corner keep near the centre line or even over it if you can, using the 3 third area, corner opens up quicker and more visibility. This is how I was taught on my motorcycle course and it was emphasised by a police motorcycle instructor when I did a one day course with IAM using the 1 third, 2 thirds, 3 thirds rule
Of course if you have good visibility on the corners then you can straighten them up a bit more.
But, it's also up to you and it's your decision, whatever you do ride safe and enjoy the roads.
