At DMG Motorsports, we present the Pirelli Diablo Rosso IV Front Tire in 120/60 ZR 17 M/C (55W) TL — the latest chapter of the legendary DIABLO ROSSO™ family and the state of the art in sport tires for road use. Engineered to set the reference in the Supersport segment, this front tire is built for supersport, naked, and crossover motorcycles that demand exceptional performance in both dry and wet conditions. Whether you're carving canyon roads or pushing the limits on your favorite stretch of tarmac, the Diablo Rosso IV delivers a perfect blend of WSBK-derived technology, advanced compound science, and race-bred profiles — all wrapped into a road-legal package that thrills at every lean angle.
Features:
- WSBK-Derived Racing Structure: Pirelli engineers developed a racing-like structure drawn directly from World Superbike Championship expertise, featuring a 3-wire strand Lyocell construction that delivers a deformation ratio considerably lower than typical street tires for superb traction during full-throttle acceleration, regardless of lean angle.
- Silica Dual Compound Front: A dual compound front design uses a hard central layer with a high silica content and low glass-transition temperature (Tg) for outstanding grip in cold and wet conditions, while a softer side layer — activated at lean angles over 35° — delivers excellent grip and brilliant contact feel.
- Race-Oriented Multi-Radius Profiles: Tire profiles are derived directly from those used in the World Superbike Championship. Multi-radius sharp contours deliver an immediate transition from lean to upright and quick changes in direction, while a flatter shoulder portion provides high grip and confident line-holding while cornering.
- Raised Rayon Cord Stiffness: The front tire features raised specific Rayon cord stiffness — obtained through larger sections of more twisted strands — allowing a lower end-count adapted along the contour, differentiating stiffness lean angle by lean angle to support dynamic performance.
- Optimized Sidewall Height: Carefully optimized sidewall height provides confident traction during both upright acceleration and corner exit, while the balance between front and rear contours ensures superb control and neutral bike behavior.
- Supersport Segment Reference: Designed to serve the full spectrum of high-performance motorcycles — from 600cc Supersport and Naked bikes to high-displacement Superbike and Hypernaked machines — making it a versatile benchmark tire in its class.
- Outstanding Wet Performance: The hard silica-enriched compound layer delivers outstanding grip in cold and wet conditions, giving riders the confidence to adjust trajectory while cornering or delay braking ahead of entering a lean.
- Tubeless (TL) Construction: Tubeless design for easy mounting, reliable air retention, and compatibility with modern 17-inch sport motorcycle wheels.
- Size & Rating: 120/60 ZR 17 M/C (55W) TL — a front-specific fitment for a wide range of sport and supersport motorcycles.
