The KTM 390 Duke is a capable urban bike that offers a good balance of power, agility, and maneuverability. It is designed to excel in urban environments and offers a sporty and nimble riding experience.
Cruising at 90 km/h (60 mph) on the KTM 390 Duke is certainly possible. It has a single-cylinder engine with a displacement of 373cc, producing around 43 horsepower. This provides sufficient power for highway speeds and overtaking maneuvers.
As for riding longer distances, covering 100 km (80 miles) in one go on the KTM 390 Duke is feasible. However, it's important to note that the Duke 390 is primarily designed as a compact and agile urban motorcycle, so it may not provide the same level of comfort as larger touring-oriented bikes. The seating position is relatively upright, which can be comfortable for shorter rides, but extended periods of continuous riding might become tiring or less comfortable compared to dedicated touring motorcycles.
For commuting in traffic and occasional day trips, a taller bike with a more upright riding position could be suitable. Some potential options to consider are adventure or sport-touring motorcycles like the Yamaha Tracer 700, BMW F 800 GS, or Honda CB500X. These bikes typically offer a more comfortable riding position, better wind protection, and are better suited for longer rides while still being nimble enough for city commuting.
Ultimately, the choice of a motorcycle depends on personal preferences, budget, and specific requirements. It's recommended to visit local dealerships, sit on different bikes, and even take test rides to find the one that best suits your needs and provides the desired level of comfort and performance.
