Metzeler RACETEC RR Radial Road Race Motorcycle Tire

The Metzeler RACETEC RR is a premium radial road race motorcycle tire engineered from Metzeler's deep competition heritage in the world's most demanding road racing events. As the only major tire manufacturer focused exclusively on motorcycle rubber, Metzeler developed the RACETEC RR to meet the extreme demands of road racing: endurance across high-mileage events, adaptability through variable conditions, and unwavering grip from the first corner to the last. The RACETEC RR has earned its reputation at the highest levels of competition — including a victory at the 2014 Supersport TT Isle of Man Tourist Trophy — delivering proven race-winning technology in a DOT-legal tire available to competitors and track day riders at all levels.

Advanced Compound Technology:

• Carbon black compound recipes blended with innovative polymers and resins to maximize hysteresis and grip — even on slippery or variable surfaces
• High-flexibility polymers conform to tarmac micro-texture for an increased contact patch and consistent grip across a broad range of temperatures and asphalt surfaces
• Patented continuous mixing process ensures homogeneous dispersion of all ingredients throughout the rubber matrix, delivering superior abrasion resistance and repeatable lap-after-lap performance
• Multiple compound options — K1 (Soft), K2 (Medium), and K3 (Hard) — allow riders to match the tire to circuit severity, asphalt friction coefficient, ambient temperature, and personal riding style
• Rear tires feature a dual-compound Cap and Base construction with a thermally conductive center strip that redistributes heat from the center tread toward the shoulders during long straights, keeping shoulder compounds at optimal operating temperature for maximum lean-angle grip

Carcass & Construction:

• Radial carcass constructed with a special Rayon fiber crown structure — characterized by high linear density and stiffness, maintaining tire shape under extreme stress and load
• Rayon fiber construction dampens the rebound stroke, absorbing and distributing forces throughout the full carcass for controlled, stable handling
• Zero-degree steel belt over the radial structure adds rigidity, reducing flex and improving grip consistency at speed
• Stiff side structure with a low deformation ratio sustains the tire architecture under stress, ensuring precise trajectory control at full lean

Performance Benefits:

• Race-level grip across a wide range of track temperatures and tarmac surfaces — engineered to perform from the first warm-up lap to the final mile
• Tread groove geometry engineered to minimize wear, disrupt Schallamach wear patterns, and maintain effective water drainage for cornering stability
• Profile designed for quick lean initiation and an expanded mid-corner contact patch for maximum mechanical grip
• High-speed straight-line stability combined with precise, predictable trajectory control through corners
• Performance integrity maintained over full road race distances — events that can span up to 240 km (150 miles), more than twice the length of a typical circuit race

The RACETEC RR is purpose-built for road racers of all skill levels and track day enthusiasts seeking professional-grade tire technology. The K3 compound variant also extends the tire's appeal to sportbike and naked bike riders who demand the highest levels of dry-weather grip on public roads. Compound formulation, tread pattern, profile, and carcass structure are calibrated in precise balance to deliver consistent performance throughout the tire's full service life.
