Vehicle Information
KTM RC 390 Motorcycle - Street (2015-2023)
The KTM RC 390, a popular lightweight sportbike, was produced from 2015 to 2023. It is known for its accessible positioning and dynamic performance, powered by a 373.2 cc single-cylinder engine. The model underwent significant developments. In 2016, it received a slipper clutch, ride-by-wire throttle, and a larger 320mm front brake. The second generation, launched in 2022, introduced a lighter chassis, a larger airbox, fully adjustable WP APEX suspension, and advanced electronic aids like cornering ABS. Horsepower remained around 43-44 hp throughout this period. Specialized racing versions like the RC 390 Cup and the RC 390 R (2018) also existed but were not standard production models for the general public. Is this part compatible with my 2017 KTM RC 390? To ensure compatibility, please use the year and edition selector on this page.
