From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Avon 3D Ultra Supersport is highly regarded by motorcycle riders for its exceptional grip and versatility across both road and track environments. Users express high satisfaction with its performance, indicating a strong intent to repurchase the product.
Pros
- Exceptional grip levels
- Suitable for both road and track use
- High rider satisfaction and brand loyalty
Cons
- Lack of data regarding wet weather performance
Observations
- Reported as a strong performance choice for middleweight naked motorcycles like the Suzuki SV650.
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
- Exceptional dry and wet grip with rapid warm-up times.
- High level of precision and confidence at deep lean angles.
- 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.
