STANDARD - Specifications: Full carbon-black tread polymer and multi-ply carcass with an under-tread breaker. - Key benefits: This is the winning tyre of the Enduro GP, suitable for demanding racing conditions with extreme mechanical and thermal tread resistance. MEDIUM - Specifications: Full carbon-black tread polymer added with plasticiser and featuring a softer carcass than the Standard 140/80-18 - Key benefits: Advised when races include a larger share of slower and technical passages. SOFT - Specifications: Lower compound hardness, proper knob stiffness and abrasion resistance; specifications are granted at all temperatures. - Key benefits: SOFT specifications are intended for slower and more technical cross-country sections also in wet conditions. SUPER SOFT - Specifications: Tread polymer with a higher ratio of plasticizers than the SOFT version; an even softer rubber with maximum adherence even on the toughest and wet technical passages. - Key benefits: Very specialised product, it delivers remarkable performance with duration compatible with 1-day racing events: The ideal working range starts a few degrees above 0°C (cooler operating conditions will result in poor performance): The prolonged employment at high speed on road at any temperature is unadvised. EXTRA SOFT - Specifications: High-hysteresis tread rubber for pure performance in extreme conditions at any temperature range. - Key benefits: Superb performance with duration compatible with 1-day duration racing events in the toughest conditions and even without momentum. Developed in combination with METZELER MOUSSE IP9253200 E-18H1-SOFT (FLAT) and IP9338100 MOUSSE E-18H1-SUPER SOFT (the SOFT simulating an equivalent inflation pressure of approx. 0.3bar).
