The key difference lies in their design and riding ergonomics:
Design: The KTM Duke series is known for its streetfighter/naked bike styling, while the KTM RC series represents fully faired sport bikes. The Duke models tend to have an aggressive and upright riding position, ideal for urban riding and versatility, whereas the RC models prioritize aerodynamics and a more forward-leaning riding posture, suitable for spirited cornering and track-focused riding.
Riding Ergonomics: Due to their distinct designs, the Duke and RC models offer different riding ergonomics. The Duke models generally provide a more comfortable riding experience with a relaxed seating position, wider handlebars for better maneuverability, and higher visibility. On the other hand, the RC models prioritize a sportier riding position with a forward-leaning stance, lower clip-on handlebars, and a more tucked-in riding posture.
Ultimately, whether the KTM Duke 125 or the upcoming KTM RC 125 is better for you depends on your personal preferences, riding style, and intended use. If you prioritize a more upright and versatile riding position, the Duke 125 might be a better choice. It's recommended to consider your specific requirements and preferences when making a decision and, if possible, review the specifications and conduct test rides once the upcoming KTM RC 125 is released.
