METZELER RACETEC RR SLICK 200/60/017 K0

As for the rear tyre, choice of version is based on asphalt friction coefficient (high severity/friction and low severity/friction, depending on the circuit or road race) and asphalt temperature (with the threshold being around 25°/30°degree).
An important aspect of the compounds development has been focused on performance consistency, through usage (miles and/or laps), and time (thermic cycles).
The addition of specific resins in the compounds recipes and the employment of a specific mixing process allow RACETEC™ RR SLICK to be used through several thermic cycles.

Note: K0 = Super Soft, K1 = Soft, K2 = Medium.
Temperature scale refers to tyre operating temperature. Compound choice can vary depending on bike setup and riding style.
