The KTM Duke 390 has a seat height of approximately 32.7 inches (830 mm). As a rider with a height of 5'3" (63 inches or 160 cm), you may find it a bit challenging to handle the Duke 390 comfortably due to its relatively tall seat height. However, it ultimately depends on your personal preference and comfort level.
It's recommended to visit a local KTM dealership or motorcycle showroom to physically sit on the Duke 390 and see how well you can reach the ground with your feet. Ensure that you can maintain a stable footing while seated, as this is important for maneuvering and balancing the motorcycle at stops.
You may also consider adjusting the suspension settings or using aftermarket modifications like lowering kits to reduce the seat height if necessary. However, it's crucial to consult with professionals or authorized technicians to ensure that any modifications are done safely and without compromising the motorcycle's performance and handling.
Ultimately, choosing a motorcycle that suits your height and comfort is important for a safe and enjoyable riding experience.
