The KTM RC 390remains a favorite among riders who want track-ready performance in a street-legal package. This latest version expands performance capabilities even further, which I discovered during two weeks of testing on both track and street. A compelling option in the entry-level sportbike segment emerges through its updated electronics package, refined ergonomics, and sharp handling. The previous generation delivered impressive capabilities, and this new KTM RC 390 elevates the experience with significant technological and performance improvements. Let's take a closer look at the features that make this Austrian machine distinctive in today's competitive motorcycle market, from its remarkable top speed to its attractive price point.
PERFORMANCE OVERVIEW
My thorough testing of the 2026 KTM RC 390 revealed its exceptional performance capabilities. The bike's heart is a liquid-cooled 373cc single-cylinder engine that pumps out a strong 44 horsepower and 37 Nm of torque.
Engine Power and Torque Analysis
The engine's character stands out in its power delivery. A 40% larger airbox and refined fuel mapping have improved the throttle response by a lot compared to older models. The bike shoots from 0-100 kph in just 5.2 seconds, making it a standout performer in its class.
Track Performance Capabilities
The RC 390 comes alive on the track. The WP Apex suspension setup has a 43mm inverted fork with 30 clicks of compression and rebound damping adjustment. The ByBre braking system with its 320mm front disk and 230mm rear disk gave me consistent stopping power during intense track sessions.
