The KTM RC390 is a sports bike with a single-cylinder engine that exhibits rather unusual power delivery for this type of engine. While single-cylinder engines typically deliver a lot of power at low RPMs, the RC390 needs about 6000 revolutions per minute to reach its optimal power band. On the plus side, the engine's smooth running without significant vibrations is advantageous for daily street use. Another positive aspect is the extensive electronic equipment, which is remarkable for a bike in this displacement class.

The seating position is supermoto-oriented, which promotes agile riding performance. The wide handlebar allows for easy and precise control of the bike. The chassis offers both comfort and sufficient damping to avoid uncontrolled movements. Another highlight of the RC390 is the option to use a quickshifter and blipper function. The gear ratios are chosen to be short, making riding shift-intensive, but this is well compensated by the mentioned additional features.

The KTM RC 390 presents itself on paper as the sportiest bike in its segment. Its fully adjustable chassis and the lowest weight are clear advantages. However, the engine shows weaknesses in performance. Especially the torque is mediocre: In the lower rev range, it takes some time to get going, it convinces in the middle, but in high revs, the performance drops off. The quickshifter works reliably, and the operation of the display and menu navigation are adequate. Particularly noteworthy is the sporty ergonomics of the RC 390, which also means that comfort suffers. This setup is aimed at riders looking for a very agile and nimble machine and are willing to sacrifice comfort for sportiness.

The KTM RC 390 impresses with its radical seating position, which is sportier than that of its competitors. This is immediately noticeable when you take a seat on the bike, as the handlebars are positioned significantly lower. The 390 cc single-cylinder engine is slightly restricted due to stricter emission standards, which can affect power delivery. The seat is comfortable, and the modern display as well as the well-functioning brakes contribute to the positive overall experience. Particularly noteworthy is the extensive electronics package, which includes the Supermoto ABS. Overall, the RC 390 leaves an excellent first impression, especially due to its sporty ergonomics and comprehensive electronics.

At first, I found it difficult to warm up to the KTM RC 390. The seating position felt uncomfortable, possibly due to the aggressive stance and forward weight distribution. This front-heavy nature required an adjustment period. However, after a few laps, I began to appreciate the bike's advantages. Although I initially criticized the precision, it turned out that the handling was quite easy due to the compact size and low weight. The brakes initially seemed too aggressive and hard to modulate, but again, I think it's a matter of getting used to them. Overall, the KTM RC 390 left a solid impression, even if it doesn't rank among my favorites.

The positive experiences with the KTM RC 390 can be summarized as follows:

Chassis and Handling: The fully adjustable chassis allows for precise adjustments to various riding conditions. The lightweight and compact size make handling easy and nimble.

Electronics and Safety Features: The electronic package is extensive and includes functional riding aids such as traction control and ABS. The Supermoto ABS is particularly highlighted, as it brings a lot of fun on supermoto tracks.

Ergonomics and Seating Position: The sporty seating position is perceived positively by some riders, as it supports agile and nimble riding performance.

Engine and Transmission: The quickshifter and blipper function make shifting easier and contribute to a pleasant riding experience. The gear ratios are well-matched.

Engine Performance: The single-cylinder engine shows weaknesses in power delivery, especially in the lower RPM range. It lacks "punch" and full power is only achieved at higher RPMs.

Seating Position and Ergonomics: The seating position is described as aggressive and front-heavy, which may not appeal to every rider. The bike is less comfortable compared to other models in the same segment, particularly noticeable on longer rides.

Brakes: The brakes are sometimes perceived as too aggressive and hard to modulate. The modulation of braking force is rated as average.
