The bike seems mechanically fine. Since I put up this post I have been reflecting on my riding. I am putting a lot of my weight on the handlebars, with a death grip too! I believe the illusion of sliding is a good description, since I’ve never actually lost control. I think I’m too tense on the corners instead of trusting my instincts. I’m probably putting most of the weight on the front tire since I”m braking late and I’m not smooth on the throttle. I’m always afraid that I’ll enter the corner too fast or give it too much throttle in the corner.
Thanks for the ideas.
