When I got my Ninja 250R rode up to my place by the previous owner, the shift pedal angle was not working for me to safely ride on the road. I would likely have struggled very badly to get my toe under the shifter and then it would be stuck there! These are all the before-adjustment pictures.
Here is the YouTube video I found and followed to do the simple but very important personalized adjustment to the shifter angle. Since then it not only becomes much safer for me to operate the shifter (crucial to riding properly), it totally feels to be MY motorcycle!
