190/55 ZR17 75W Pirelli Diablo Rosso IV

The Diablo Rosso IV is engineered as a hypersport road tyre for riders who want sharp steering response, strong dry surface grip and predictable behaviour in mixed conditions. Its construction, compound layout and tread geometry are derived from Pirelli’s performance focused development programmes, giving the tyre fast warm up, stable cornering support and consistent feedback at high lean angles.

The Rosso IV uses size specific carcass materials and compound zones to ensure that each fitment delivers the correct balance of rigidity, traction and stability. This allows the tyre to adapt to a wide range of motorcycles while maintaining the precise, agile handling associated with Pirelli’s hypersport DNA.

Key Technical Characteristics

Size Specific Structural Design The front tyre uses a stiff chord arrangement with a reduced end count to improve steering precision and handlebar response. Rear tyres up to 190/50 ZR17 use a rayon based structure for clear feedback under throttle. Rear tyres 190/55 ZR17 and above use three strand lyocell cords, increasing carcass rigidity and improving traction when accelerating out of corners. This tailored approach ensures stability, feedback and responsiveness across all sizes.

Dual Compound Front Construction The front tyre combines a harder, silica rich centre with softer silica based shoulders. 

The shoulder compounds increase grip at lean and reduce warm up time. This layout provides consistent performance in both dry and wet conditions.

The centre compound supports stability and abrasion resistance.

Cap and Base Rear Compound Layouts Two rear tyre configurations are used depending on size:

2 compound / 3 zone layout (up to 190/50 ZR17): hard centre for stability, soft shoulders for grip.

3 compound / 5 zone layout (190/55 ZR17 and above): racing influenced shoulder compounds for maximum dry grip potential. Both systems maintain stability under load while delivering strong traction during cornering.

Advanced Tread Geometry The tread pattern uses a combination of FLASH style central grooves and reduced lateral grooves to improve water evacuation and maintain smooth feedback at lean. A lower void to rubber ratio increases the contact area, supporting stability, uniform wear and predictable behaviour in mixed conditions.

Profiles Developed from WSBK Experience The 120/70 ZR17 front and 200/55 ZR17 rear profiles are derived from World Superbike development, offering rapid turn in, precise line holding and stable behaviour at high lean angles. This profile pairing gives the tyre a racing influenced steering character while remaining suitable for road use.

Technical Summary

The Diablo Rosso IV is designed for riders who want a hypersport tyre with:

• Strong dry grip performance and rapid warm up
• Precise steering response from size specific carcass materials
• Stable cornering behaviour supported by multi zone compounds
• Reliable wet surface performance from silica rich compounds and efficient tread geometry
• Consistent feedback during braking, cornering and acceleration

Its compound system, structural tuning and racing influenced profiles work together to deliver a tyre that feels controlled, stable and confidence inspiring across fast road riding and everyday use.
