Following our test with the Metzeler Sportecs, we slipped a 190/50 rear Sportec onto the F4i and rode a portion of the test loop for a practical comparison. With no changes to suspension or geometry, the F4i felt substantially different with the wider tire. With the bike straight up and down, steering was slightly sluggish in comparison, but just off vertical, the F4i was quite tippy and darted into corners. The light, neutral steering of the Sportecs was completely changed and the bike lost its balanced feel. The sensation was very much like riding on a tire squared off from too many freeway miles. At higher lean angles, performance was less affected, although making transitions from side to side was unpredictable. And, contrary to the popular myth that the wider tire puts down a bigger footprint and gives more traction, we felt no improvement in that department from the properly sized tire.
