Intended as a high‑performance rear tyre for sport motorcycles, the Pirelli DIABLO ROSSO IV Rear 190/50R17 73W is tuned for spirited road riding and track days. It complements front sport tyres to provide balanced grip during aggressive acceleration and lean angles. The compound and tread design prioritise wet grip without compromising hot grip at higher temperatures. Optimised contact patch and adaptive tread blocks improve tyre adhesion throughout the lean range. Steering response remains sharp, giving the rider precise input at all times.

Construction uses a carcass tuned for rapid heat build‑up and consistent operating temperature across the tyre. Multi‑compound technology provides a stable centre for straight‑line durability and softer shoulders for cornering grip. Water evacuation channels are integrated to maintain stability in changeable weather and to limit loss of adhesion during sudden rain. The profile smoothing supports predictable cornering stability and controlled slip angles.

Riders benefit from shortened braking distance, confident turn‑in and reliable traction on exit. The tyre offers a clear feedback loop to the rider and dependable mileage for aggressive road use. Overall it is a performance‑oriented rear tyre that balances track capability with practical road usability.
