The 2025 KTM RC 390 marks a major leap forward for the brand’s faired supersport lineup, offering both power and precision in equal measure. This new model doesn’t just evolve—it transforms the RC series into a more aggressive, feature-packed machine inspired by KTM’s MotoGP pedigree.

Engine and Performance Upgrades
At the heart of the 2025 RC 390 is a brand-new 399cc liquid-cooled, single-cylinder DOHC engine—the same unit that drives the latest 390 Duke. This is a significant step up from the older 373cc engine, promising a spirited performance boost. The new motor is expected to deliver around 46 PS of power and 39 Nm of torque, ensuring stronger acceleration and improved high-speed stability.
A revised airbox and updated engine mapping further refine throttle response, making power delivery smoother across all rev ranges. Heat dissipation has also been optimized with a curved dual-fan radiator that channels warm air away from the rider’s legs—an improvement riders will appreciate in city traffic and during long rides alike.
Lightweight Chassis and Handling
KTM hasn’t merely focused on engine upgrades. The 2025 RC 390 sports a re-engineered chassis that’s both lighter and stiffer than before. The new steel trellis frame paired with a bolt-on subframe enhances cornering agility, making the bike easier to handle in tight turns.
Weighing in at 172 kg (kerb), the model benefits from newly designed bionic alloy wheels and lighter braking components—reducing unsprung mass and improving suspension performance.
MotoGP-Inspired Design and Aerodynamics
Design-wise, KTM has drawn heavily from its MotoGP experience. The full fairing now cuts a wider and sharper profile, integrating a single-pod LED headlamp, a large aerodynamic windscreen, and seamlessly fitted turn indicators. The reshaped bodywork not only gives the RC 390 an assertive stance but also improves airflow stability at higher speeds.
Advanced Technology and Smart Features
Inside the cockpit, riders are greeted by a fully digital 5-inch TFT color display that seamlessly integrates with KTM MY RIDE connectivity. Through Bluetooth pairing, users can manage calls, messages, music, and navigation directly from the handlebar controls.
Enhanced Electronic Rider Aids
In the electronics department, the 2025 RC 390 brings features typically reserved for higher-capacity motorcycles. It includes Motorcycle Traction Control (MTC), lean-sensitive cornering ABS, and a bi-directional Quickshifter+ for effortless clutchless gear shifts both up and down.
Riders can also toggle modes through “Supermoto” ABS for controlled slides or aggressive braking on the track. Additional riding modes like Street and Rain allow for custom-tailored performance no matter the road conditions.
The Verdict
With all these refinements, the new RC 390 isn’t just a sportbike—it’s a balanced mix of everyday practicality and race-ready precision. Lighter, sharper, and more intelligent, this motorcycle redefines what a sub-400cc machine can deliver. Indian enthusiasts can expect the 2025 KTM RC 390 to arrive soon, likely at a slightly higher price point, but with unmatched performance and technology for its class.
