💬 Summary

• ✅ Dunlop Q5S is an excellent choice for sporty street riders who might dabble in track use but want long-lasting, confidence-inspiring grip.

• 🔥 Compared to Q5, it sacrifices peak grip and track handling for more usable road performance and longevity.

• 🔁 Competing tires like the Rosso IV, Power GP, and S22 are close contenders depending on whether you value wet grip, nimbleness, or comfort.

If you're on something like a KTM Super Duke R, Yamaha R1, or S1000RR and spend 80% of your time on the street, Q5S is one of the best tires available right now. For pure track, Q5 (or slicks) are still king.
