Why this suspension upgrade works

The single-tube design delivers rapid damper response, so bumps are absorbed cleanly and the chassis stays composed. The inverted strut adds stiffness where it matters, keeping the front end planted when you turn in. Expect less roll, better traction on exit and a more connected feel without harshness.
