Metzeler KAROO EXTREME 90/90-21 54S TT M+S front tire

Total control

The layout of the front studs is specifically designed to provide stability on both straights and bends. The central studs feature a special shape which, thanks to their height, the different directions taken by the active edges and their position in a triangular layout, offers maximum traction when braking and stability on both soft and compact terrain.

Lateral studs support the bike in bends and offer precise trajectory and directionality when leaning, ensuring incredible safety.

Total stability

The structure of the KAROO™ Extreme uses a high-modulus/low-shrinkage fiber with a multi-layer carcass that offers a contact feel, stability when braking and maximum flexibility to absorb forces when over jumps or obstacles. It also features a very light structure to promote high-speed stability and excellent handling. The structure has been specially developed for extreme off-road competitions with inner tubes and foams, and for use with heavy and powerful motorcycles in rallies, on long special stages at high speeds, often during hot seasons and on constantly changing terrain.

Tear and wear resistance of studs

The KAROO™ Extreme compound formulation combines natural rubber for mechanical strength and a synthetic rubber for wear and tear resistance.
The high percentage of carbon black increases resistance to all types of stress, even at high temperatures typical of desert racing, and makes the studs resistant to tearing and premature wear.
On hard terrain, the compound prevents the tire from overheating, reducing the risk of explosion or blistering during races. Thanks to improved flexibility, the structure offers excellent puncture resistance even at low pressures.
