KTM has taken the motorcycle world by storm with the unveiling of its flagship 1390 Super Duke R in Europe. Beyond its impressive electronic features, this naked streetfighter introduces a sophisticated variable valve timing system, setting it apart from the crowd.
Variable Valve Timing: While variable valve timing is not a new concept, the 1390 Super Duke R goes a step further with variable cam duration and cam lift. This cutting-edge system, reminiscent of BMW’s ShiftCam technology, promises a dynamic riding experience.
How it Works: KTM’s cam shifting system utilizes two cam lobes for each valve – the ‘mild’ and ‘wild.’ The ‘mild’ cam provides lower lift and duration, enhancing low-end torque, throttle response, and reducing emissions. On the flip side, the ‘wild’ cam offers increased lift and duration, optimizing top-end performance.
Swift Transitions: What sets KTM apart is its efficient switching mechanism between the two cam profiles, accomplished in less than 22 milliseconds. This seamless transition ensures riders experience the best of both worlds, whether cruising at low speeds or pushing the limits for maximum power.
Performance Benefits: The result? A broader spread of power and torque across the rev range, providing riders with unparalleled control and versatility. Whether navigating city streets or conquering open highways, the 1390 Super Duke R delivers an exhilarating performance.
