Racetec Interact K3

New patented tread pattern concept with advanced grooves for even wear and total stability when accelerating out of corners

  • K3 compound. Specification dedicated for street use, bringing the winner of many National Championships to the normal road
  • State of the art compounds for maximized cornering grip at full lean angles: faster cornering, with total stability of trajectory
  • Modular steel cord winding tension of the patented 0° steel belt, to ensure excellent braking stability with precise turning-in: high level of feedback and progressive feeling of grip at the limit

“.. is a masterpiece. Indulgent tyre with perfect stability and accuracy on a high level...”

Technical Data

Steel radial

Innovative belt structure with a single ply of steel cords wrapped around a radial carcass at 0°. Patented high performance technology by Metzeler for both front and rear tyres.
Steel features a higher stiffness than textile and this allows the reduction of the tyre weight. Steel radial belt reduces the dynamic deformation of the tyre under centrifugal forces giving  the tyre an excellent high-speed stability. Thanks to the more uniform heat distribution, mileage is increased and wear characteristics are more uniform.

Metzeler Advanced Winding
“Metzeler Advanced Winding” is a patented system for optimum spacing between the cords of the 0° steel belt. In certain sections of the tyre, the steel cords are wound with different spacing depending on the performance requirements on that particular area of the tyre. On both front & rear tyre the spacing is wider in the crown area for more elasticity and self-damping. For sections of the tyre used for mid lean, there is increased stiffness to support fast cornering. On the shoulder area on the rear tyre, the spacing is again wider for safe feedback and control when riding towards full lean.
Contour Modelling Technology

Advanced design technology of the tyre contour is tuned to meet high performance riding demanded on the latest bikes. A combination of different profiles on front and rear are optimised to be complimentary at any given angle of lean. The final contour design of the tyre set features the best aspects of performance for every riding style on all of the latest bikes: predictability, feedback at the limit of grip and cornering stability.

Interact: Multi-Zone-Tension

Multi Zone Tension.
Modular steel cord winding tension: the performance of the tread compound depends on the stiffness of the structure underneath. Performance exactly where needed, giving maximum adaptability to different riding styles.
