Pros and Cons in comparison

KTM RC 390 2023

The KTM RC 390 presents itself as a sporty and dynamic bike that is particularly suitable for riders looking for an agile and manoeuvrable machine. Its fully adjustable suspension and low weight ensure precise and easy handling, while the comprehensive electronics package, including the innovative supermoto ABS, offers additional safety and riding pleasure. The engine, on the other hand, shows weaknesses in power delivery, especially at low revs, which is not what you would expect from a single-cylinder engine. The aggressive riding position is a double-edged sword: it enables a sporty riding experience, but can be uncomfortable for longer rides.
