Metzeler presents the new Sportec M9 RR

Road Racing


The new Metzeler has been designed to offer the highest level of grip, handling and safety even in unexpected situations such as in wet conditions and uneven roads.

Grip, even in wet conditions and manoeuvrability are the features Metzeler focused on in creating the new Sportec M9 RR. The new Metzeler has been designed bearing in mind the needs of super-sport and naked bike owners who ride every day and in all weather conditions. The name Sportec M9 RR consolidates a link with Metzeler's technological legacy: Sportec, in fact, is synonym of hi-performance while the suffix RR - an acronym for Road Racing - refers to competitions such as the Isle of Man Tourist Trophy, the 2019 edition of which saw the victory go to a bike equipped with Metzeler Racetec RR Slick tires. The brand has historically used road racing as a test bench to enhance the performance and versatility of its products thanks to the wide range of conditions found during these events. The Sportec M9 RR has been designed, in fact, to perform in a wide range of conditions and temperatures: dry or wet.



Both the front and rear feature Full Silica shoulder compounds tested on full rain tires, refined to stabilize their behaviour at high temperatures, and new formula Full Silica central compounds. The rear tire was designed using the Cap & Base scheme, which consists of overlapping the two soft compound sidewalls, which ensure grip when cornering, with a harder compound layer that ensures consistent performance and thermal balance. The latter compound makes up the centre of the tire for about 50mm, or 25 per cent of the entire section, to improve mileage. The silica content in the rear centre belt was increased by 24 per cent compared to the Sportec M7 RR. Identical characteristics are also present on the front tire, which uses the same compounds as the rear tire to ensure uniformity of response front and back. Another important feature is the use of Compound continuous mixing (Ccm) technology. This is a patented mixing process able to maximize the dispersion and uniformity of the components in the polymer matrix. The resins used in combination with silica give the final formulation a stable behaviour over a wide temperature range.


Structure and design

Metzeler engineers created a rayon structure for the Sportec M9 RR that is 6 percent stiffer than its predecessor, characterized by lower density and the use of a larger amount of rubberizing compound. The pi-shaped grooves in the tread pattern - a distinctive feature of Sportec products - allow a certain degree of mobility and maximize the volume of water evacuated when tackling wet roads. The central claw-like carvings of the Sportec M9 RR stem from the company’s experience with its Racetec RR. The shoulders of the Sportec M9 RR are slick, possibly even more than its predecessor, in order to improve support and lateral thrust in maximum bends where the water evacuation function is no longer required.
