Review

The 2026 QJ Motor SRK 421 RR is designed to challenge the status quo in the high-revving four-cylinder middleweight supersport category, directly competing with rivals like the Kawasaki Ninja ZX-4R. At its heart lies a 421cc inline-four engine that screams to 14,000 rpm, delivering a peak output of 77.5 horsepower. This engine configuration provides the iconic high-pitched exhaust note and linear power delivery that enthusiasts crave. The chassis utilizes a hybrid design of aluminum plates and a steel trellis frame to balance weight and structural integrity. Premium components define the SRK 421 RR's hardware. It features fully adjustable Marzocchi upside-down forks and a matching rear monoshock, paired with Brembo radial-mount calipers for exceptional stopping power. The electronics suite is equally impressive, featuring a 5-inch color TFT display with smartphone connectivity, integrated navigation, traction control, and dual riding modes (Sport and Normal). Functional aerodynamic winglets and a sharp LED lighting signature emphasize its racing DNA. Optimized for both track days and spirited street riding, the SRK 421 RR is fully compliant with Euro 5+ emission standards, making it a modern and accessible performance machine.
