Metzeler Racetec SM Racing Tires

New supermoto-specific rubber promises improved control and feedback.

Metzeler, a branch of Pirelli specializing in motorcycle tires, has introduced a new generation of rubber specifically conceived for supermoto racing. This new range wears the traditional Racetec label that identifies Metzeler’s racing products, complete with the suffix SM.

Racetec SM will come in three grades of compounds: In addition to the already known K1 (soft) and K2 (medium), now comes also K0, an even softer compound said to ensure control and traction under demanding conditions.

Structure and profiles were developed with assistance from a proprietary software named Contour Modeling Technology that creates complementary front and rear shapes to give the riders the best possible feedback and control of the bike at any lean angle.

Metzeler also uses a unique approach to the solution of the problem of obtaining a uniform working temperature on any area of the tire by exploiting the hysteresis characteristics of rubber. The carcass/belting structure is calculated to flex more, thus inducing more heat buildup in less-stressed areas while remaining more stable at highly loaded points. Greater shock-absorbing capability is also claimed.

In addition to three compounds, Racetech SM will come in a treaded rain configuration and a new front measurement: 120/75-16.5. All other specialized supermoto sizes will also be available.
