Pros

The Pirelli Diablo Rosso IV is widely regarded as a top-tier hypersport tire that offers significant improvements in feedback, warm-up time, and lean-angle confidence over its predecessors. While users consistently praise its performance in both wet and dry conditions, the consensus notes that these gains come at a premium price point and with potential longevity trade-offs depending on riding style.
Pros

- Improved feedback and stability compared to previous generations (DR2/DR3).
- Surprisingly good low-speed stability and handling characteristics.
Cons
- Higher price point compared to competitors and previous models.
- Performance consistency may degrade as the tire reaches the end of its service life.
- Potential for increased wear rates under aggressive riding conditions.
Observations
- Users reported significant improvements in resistance to cupping on smaller displacement bikes (e.g., PCX 125) compared to the Diablo Rosso II.
- Aggressive riders utilizing standard sportbike sizes (120/70 and 190/55) report that the tire maintains performance characteristics comparable to more track-focused compounds like the Rosso Corsa II.

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
