Metzeler’s Sportec M5 Interact offers motorcyclists cornering confidence with its 5-zone tension technology and a lean angle indicator for the best grip.

With the new Sportec M5 Interact, the premium German brand opens a new chapter in motorcycle tire construction: an innovative 5 zone tension technology inside brings a custom-tailored grip level, excellent handling and confident stability at every lean angle demanded in any driving condition. This technology, along with Greek “Pi”-inspired tread grooves specifically placed for maximizing tire flexibility and new high-silica compounds for supreme dry grip and wet confidence, elevates the Sportec M5 Interact as the ideal tire for all sport bikes and naked bikes, from its high performance capabilities to its clean all-round look.

Following the sport-touring Roadtec Z6 Interact and the racing-oriented Racetec Interact, comes the new Sportec M5 Interact, the perfect all-round supersport tire from Metzeler boasting innovative Interact Technology. This all-encompassing approach to development perfectly matches the tire’s structure, 0°-steel belt, tread design and compounds for a combination of high performance even in wet conditions, rideability and wear uniformity.

Interact: 5 Zones Tension Technology
Metzeler engineers answered the most diverse requirements of the supersport segment with a new stage of development on the tensions of the tire’s steel-belt: The new Sportec M5 Interact boasts five well-defined zones over the entire contour of the tire, achieving always the best grip lean for each angle, stability and constant feedback.

Interact technology is a precise tuning of the high-tech steel belt winding tensions combined with a perfectly matched carcass, without the discontinuity experienced by alternative multi-compound products. With this new structure, Metzeler engineers also succeeded in optimizing the total area of the tire footprint at every lean angle with up to an 8% increase, while improving also its shape and pressure distribution. This success is felt in every situation: with an increased stability in a straight line, better contact feel at the central part of the curve and safe grip at full lean.

The tread pattern of the new Sportec M5 Interact is the result of an extensive series of tests to achieve high effectiveness in dry (stability) and wet (drainage) conditions, but also provides an increased life for the tire. The registered design of the Sportec M5 Interact tire tread resembles the Greek letter “Pi”, a component to the formula of a perfect circle. The shape and distribution the tread grooves contributes to the overall performance of the Sportec M5 Interact with very effective water drainage as well as a superb flexibility. This increased flexibility complements the Interact-based tire structure in maintaining an optimized contact area to avoid slippage which positively affects wear uniformity and thus mileage.

High Silica Mixture
The two newly developed tread compounds of the Sportec M5, unique between front and rear, seamlessly partner with the Interact structure. Derived from a completely new mixing procedure and produced with a larger percentage of silica, they bring top-of-segment adhesion on dry land as well as uncompromising confidence in wet conditions, still keeping a rapid warm-up time for a maximum supersport grip level right from the first pull of the throttle.

Lean Indicator
An additional motorcycle tire first comes from the Sportec M5’s new lean indicator which offers riders visual confirmation of the maximum level of the tire’s usage: riders can verify which of the 5-stage markings were contacted while riding. The five lean indicator markings are placed on the shoulder of the rear tire where the profile meets the road surface at angles of approximately 25°, 30°, 35°, 40° and 45° (depending on vehicle weight and tire pressure).

The new Sportec M5 Interact will be available starting from the 1st of February, 2010 in front size: 120/70ZR17; as well as three rear sizes: 180/55ZR17, 190/50ZR17 and 190/55ZR17, and shall gradually replace its successful predecessor, the Sportec M3.

Front size 120/60ZR17 and rear size 160/60ZR17 will follow in April 2010.

Sportec M5 Interact has already completed homologation for most modern sport bikes and naked bikes and for more specific fitment, please visit Metzeler’s website: where you will find the latest releases, technical details for the entire motorcycle tire range and find your local dealer.
