While the KTM Duke 250 is generally well-regarded, there have been some reported issues and considerations worth noting. It's important to keep in mind that individual experiences can vary, and these issues may not apply to every owner. Here are a few points to consider:
Vibrations: Some riders have reported experiencing vibrations at higher speeds on the KTM Duke 250. However, the severity of vibrations can vary from person to person, and what one rider may consider excessive, another may find acceptable. It's advisable to test ride the bike and determine if the level of vibrations is within your comfort zone.
Ergonomics: The Duke 250 has a sporty and aggressive riding position, which some riders may find uncomfortable for long rides or extended periods of cruising. The seating position is more forward-leaning, which can put strain on the wrists and back. It's recommended to assess the ergonomics during a test ride to ensure it suits your riding preferences.
Engine heat: A few riders have reported that the KTM Duke 250 can generate significant heat, particularly in heavy traffic or during slow-moving rides. This heat can be felt around the rider's legs, which may be uncomfortable in certain situations.
Regarding comfortable cruising speed on a highway, it generally depends on various factors such as road conditions, wind, and personal preference. However, the KTM Duke 250 is capable of cruising comfortably at speeds between 70-90 km/h (43-56 mph). It can go faster, but some riders may experience increased vibrations or discomfort at higher speeds due to the bike's design.
In terms of vibrations, the KTM Duke 250 is generally known to have more vibrations compared to the Bajaj Dominar 250. The Dominar 250 is a cruiser-style motorcycle with a more relaxed riding position, which helps reduce vibrations and offers a smoother ride. If minimizing vibrations is a priority for you, the Dominar 250 might be a better option.
As with any motorcycle, it's recommended to conduct thorough research, read owner reviews, and consider a test ride to evaluate the bike's performance, comfort, and suitability for your riding preferences.
