• Silica-enriched multi-compound for both front and rear tyres
  
• Best performance on road use, on both wet and dry roads
• Use case: On-Road/Supersport
• Tailored structure on application:
  • WSBK derived 3-strand LYOCELL™ wire for 190/55 ZR 17 and sizes above
    
  • Stiffer RAYON chords for fronts and rear sizes up to 190/50 ZR 17
    
  • Optimized footprint geometry in all lean angles and loads, excellent dynamic response to power unit outputs, quicker handlebar response
• More rubber:
  • More space for rubber thanks to lower ply chords end-count
    
  • Enhanced dumping effect on asphalt micro-roughness
    
  • Excellent riding feeling and reduced tire noise on imperfect tarmac
• Tread pattern design:
  • Mid-lean area with reduced void/fill ratio
    
  • Higher footprint area and better stress distribution enhancing grip at mid-lean
• Contour:
  • New front profile with reduced curvature on shoulders
    
  • "Wider contact patch in full lean
    
  • Lightening handlebar response to rider inputs and smooth feedback while cornering, for enhanced riding control
• Compounds:
  • Cap&Base multi-compound layout
    
  • Quick warm-up and enhanced thermal balance
• FLASH grooves:
  • FLASH tread pattern design
    
  • Outstanding stability on wet, by draining more water as speeds increase and as the weather worsens
• High Silica compound:
  • High silica front and rear compounds for a solid chemical grip both on dry and wet tarmac
    
  • Best performance on road use, on both wet and dry road
• Tailored Specification:
  • Within motorcycles scenario, high-displacement (> 999 cc) bikes set 200hp as a standard threshold, often reaching the astonishing power of more than 215hp for several Superbike and Hypernaked machines. In this picture, we must include also sporty crossovers capable of delivering 160hp on 240kg machine more than 140 cm tall and 600cc Supersport and Naked bikes with almost the same weight of the bigger displacement counterpart but with no more than a half of the power.
  • DIABLO ROSSO™ IV sets a reference in the Supersport segment for all these classes of motorcycles. Therefore PIRELLI decided to differentiate the rear tyres product characteristics based on the size, and therefore the type of motorcycle in order to perfectly deliver the requirements for each rider.
• Structures:
  • Rear tyres from 190/55 ZR 17 above:
    • PIRELLI engineers developed a racing-like structure, derived from World Superbike Championship expertise: DIABLO ROSSO™ IV features a 3-wire strand Lyocell structure which translates in a deformation ratio considerably lower than usual for street tyres. The net result of this is superb traction during full-throttle acceleration, regardless of the lean angle.
• Contour:
  • DIABLO ROSSO™ IV features race-oriented profiles derived by the ones used in the World Superbike Championship. Multi-radius sharp contours deliver an immediate transition from lean to upright and a quick change in direction, whilst a flatter shoulder portion provides high grip and line holding while cornering. Optimized sidewall height provides confident traction during both upright acceleration and corner exit. Balance between front and all rear contours allows a superb control feeling and neutral bike behavior.
• Compounds:
  • A dual compound front tyre is coupled with Cap&Base layout rears: a dual compound for low to medium displacement motorcycles and a tri-compound for Superbike and Hypernaked machines.
  • Tri-compound rear tyres, from 190/55 ZR 17 above:
    • Introducing an endurance-racing compound, the 5-zone layout moves the trade-off on high lean angles from wet grip to thrust boost to cope with the extreme cornering speed and the astonishing engine outputs of modern performance motorcycles. The soft full silica mid rubber strip ensures performance whilst delivering a safe sporty ride – across all weather conditions.
• Tread Pattern Design:
  • As a distinctive sign for PIRELLI sporty products, DIABLO ROSSO™ IV tread pattern is developed around the FLASH icon: a couple of center grooves which provide directional stability and ensures wear stability. FLASH is also accountable for water draining from the center to outside the contact patch when upright.
  • FLASH tails of varied length are distributed surround the center design, outlining mid-lean grooves. Tails are a constitutive element of the tire behavior, providing the right tire flexibility and efficient water evacuation and an absolute wear uniformity.
  • Tread Pattern design of DIABLO ROSSO™ IV with slicker mid-lean areas evolves the DIABLO ROSSO™ III one, giving support at lean angles where water drainage is useless, which means over 35°. It is characterized by a large slick area on shoulders, which results in excellent grip and line holding while cornering at extreme lean angles. Besides the family feeling, tread pattern layout plays a relevant role in DIABLO ROSSO™ IV performance.
• Benefit & Performance:
  • The sportiest tire for road use, regardless of the weather conditions
  • Superb grip while braking, thrust boost in extreme lean angles and brilliant traction exiting the corner
  • Lightening handlebar response to rider inputs and smooth feedback while cornering
  • Best performance for road use, on both wet and dry roads
