Engine Displacement: 373.2 cc
The RC 390 continues to utilize the high-performance 373.2 cc, liquid-cooled, DOHC single-cylinder engine. For 2026, it features a carbon-coated cam follower for extreme reliability at high RPMs and a 40% larger airbox compared to previous generations, improving throttle response and torque delivery.
Max Power: 43.5 PS @ 9,000 rpm
With a power output of 43.5 PS, the RC 390 offers a power-to-weight ratio that makes it one of the fastest motorcycles in its class. The engine is tuned to deliver a racing-inspired power surge in the upper rev range.
Max Torque: 37 Nm @ 7,000 rpm
Generating 37 Nm of torque, the RC 390 provides strong "pull" out of corners. The torque curve is flatter in the 2026 model, making it more forgiving for city riding while remaining explosive on the track.
Top Speed: 175 km/h
The RC 390's top speed is limited more by gearing than power, reaching a true top speed of approximately 175 km/h. Its aerodynamics are inspired by KTM's RC16 MotoGP bike, reducing drag significantly when the rider is in a full tuck.
Mileage: 28 kmpl
Given its high-performance state of tune, the RC 390 delivers roughly 28 kmpl in mixed conditions. For highway touring, this can improve to 30-31 kmpl depending on rider weight and aero-efficiency.
