K 2 is the more aggressive karting compound in the range, developed around a higher friction level and strong initial response while maintaining clean, controlled release behavior. It is intended for high-friction kart racing on both front and rear axle applications, making it well suited to drivers who want greater stopping authority without sacrificing modulation or control. With its combination of high friction, excellent initial bite, outstanding release, and strong thermal resistance, K 2 delivers a sharp, confident braking character for demanding kart racing conditions.
