Metzeler SPORTEC 01 and SPORTEC 01 RS: Two New Supersport Tires with Adaptive Tread Technology

• Two models for different purposes: SPORTEC 01 for the road, SPORTEC 01 RS also for the track
• New patented DYNATREAD technology adapts tire behavior to load and riding style
• Development based on know-how from road racing, particularly the Isle of Man TT

Metzeler expands its supersport portfolio with two new tires, each pursuing a distinct approach. The SPORTEC 01 and the SPORTEC 01 RS share the same technological foundation but differ significantly in their design philosophy and target audience. According to Metzeler, both models are the result of a completely new development project in terms of tread design, compounds, and structure. Experience from road racing, particularly from the partnership as official tire partner of the Isle of Man TT, is said to have played a central role.

Same Foundation, Different Philosophy

Despite their shared DNA, the two tires target different types of riders. The SPORTEC 01 is designed as a versatile sport tire that aims to combine high dry performance with good wet-weather capability. Its handling is described as precise, intuitive, and easy to control. This makes it ideal for sportily oriented riders who primarily use their motorcycle on the road and want confidence in their tires even in changing weather conditions. Metzeler names supersport machines, naked bikes, and sporty crossover models as typical applications.

The SPORTEC 01 RS takes performance a step further. It was developed for experienced riders who demand maximum dry grip, high steering precision, and very direct handling. The highlight: despite its race-oriented design, it carries full road approval and is therefore suitable for track days without requiring a cumbersome tire change at the circuit. The target group here is primarily riders of supersport machines, high-performance naked bikes, and hypernaked models.

DYNATREAD: Patented Adaptive Tread System

The technological core of both tires is the new, patented DYNATREAD technology. This is an adaptive tread system designed to adjust the tire’s behavior to the specific demands placed upon it. During braking, acceleration, and under high load, the tread grooves close dynamically, increasing the contact patch. This maximizes the contact between rubber and asphalt precisely when the greatest grip is needed. In less demanding riding situations, the grooves remain open, providing effective water drainage among other benefits.

According to Metzeler, DYNATREAD is also intended to reduce the mechanical and thermal stress on the tire, thus counteracting overheating. For the rider, this means more control and a more consistent performance level over a longer period. On the road, the technology is said to enhance safety and versatility, while on the track it provides high grip and consistent precision.

Tread Design: Versatility vs. Extreme Performance

Both tires feature a unified tread design for front and rear. This solution is intended to ensure consistent behavior during braking and acceleration, providing the rider with homogeneous, predictable feedback.

For the SPORTEC 01, the tread pattern has been completely redesigned compared to the previous Metzeler supersport generation. The design inspired by the Greek letter Pi has been retained but is now said to improve water drainage, increase directional stability, and perform well in both wet conditions and dry, sporty riding. The tread grooves work progressively with increasing lean angle, promoting rapid warm-up, consistent grip, and balanced handling.

The SPORTEC 01 RS takes this concept to the extreme. Its tread surface is smoother and more compact, with the void ratio further reduced under load. The goal: to maximize the contact patch on dry asphalt and approximate the behavior of a slick tire during very sporty riding.

Compounds: Silica for Control, Racing Compounds for Grip

The rubber compounds differ significantly between the two models. The SPORTEC 01 uses a bi-compound architecture with a high silica content on both front and rear tires. The front tire offers a more stable center area for high braking stability, while the shoulder zones feature higher hysteresis for grip at lean angles. On the rear tire, the center strip is designed for stability and mileage, while the shoulders focus on traction and acceleration.

The SPORTEC 01 RS opts for a sportier variant of the bi-compound concept. The center section uses a full-silica compound to ensure stability and road suitability. The shoulders, however, employ race-derived carbon black compounds drawn from Metzeler’s road racing experience, particularly from the Isle of Man TT. These are designed to deliver high grip and stability at lean angles while being suitable for both road use and track days.

A distinctive feature of the RS model is the base layer in the shoulder area, derived from racing. This compound is softer than the contact surface compound facing the road. On the front tire, this base layer consists of pure silica and covers both the tread and shoulder area. On the rear tire, it is made of carbon black and is present only at the shoulders. This construction is intended to enable rapid warm-up, high grip, and consistent feedback even during sustained, intensive use.

Different Carcass Structures

The two tires also take separate paths in their construction. The SPORTEC 01 is engineered so that front and rear work together harmoniously. The front tire features a dual rayon carcass and a steel belt with a 0-degree arrangement for braking stability and precise turn-in. The rear tire uses a single-ply rayon carcass with a 0-degree steel belt as well, which is designed to provide a wide contact patch and good support during acceleration.

The SPORTEC 01 RS takes a different structural approach, employing a completely redesigned construction using PET material. An exception is the 200/60 size, which continues to use a rayon carcass. The PET structure is intended to deliver stability at high speeds, maximum steering precision, and full control under extreme riding conditions. It is specifically designed to work optimally with the race-derived compounds and to unlock the full potential of the DYNATREAD technology.

Metzeler and Road Racing

The development of both tires stands in a long tradition. Metzeler has been an integral part of the most important road racing competitions for years and serves as the official tire partner of the Isle of Man TT. The brand is also present at the North West 200, the Ulster Grand Prix, and the Macau GP. These races on public roads are considered particularly demanding, as the tires must deliver grip, stability, and reliability on uneven road surfaces at the highest speeds. According to Metzeler, the collaboration with road racing specialists has significantly influenced the technical development of their products. The insights gained from this work feed directly into the development of the supersport tires, which is said to be concretely reflected in the two new SPORTEC models.
