Introduction to the KTM RC 390

The KTM RC 390 is a fully-faired sportbike designed for riders who want a taste of MotoGP-inspired performance in a compact, affordable package. Launched as part of KTM’s RC (Race Competition) lineup, this bike is built to deliver adrenaline-pumping rides on both the street and the track. With its lightweight chassis, powerful engine, and advanced electronics, the RC 390 has earned a reputation as a go-to choice for riders who prioritize performance over everything else.

Since its debut, the RC 390 has undergone several updates, with the 2022 model bringing significant improvements in engine refinement, ergonomics, and technology. Priced at approximately ₹3.21 lakh (ex-showroom) in India, it’s a premium offering in its class, but does it justify the price tag? Let’s break it down with a detailed look at the KTM RC 390 specs, design, and real-world performance.

Design and Styling

The KTM RC 390 is a head-turner, and its design screams aggression. Inspired by KTM’s MotoGP racing heritage, the bike features sharp, angular lines and a low, crouched stance that gives it a predatory look. The 2022 update introduced a sleeker fairing, a larger windscreen, and revised decals that enhance its aerodynamic appeal. Available in vibrant color schemes like KTM Factory Racing Blue and Orange, the RC 390 stands out in a crowd.

Key Design Highlights

• Aerodynamic Fairing: The full fairing reduces wind drag, making high-speed rides more stable.

• LED Headlights: Twin projector LED headlights offer excellent visibility and a modern aesthetic.

• Compact Dimensions: Despite its aggressive look, the RC 390 is compact, making it easy to maneuver in city traffic.

• Side-Slung Exhaust: The sleek exhaust design adds to the bike’s sporty vibe while keeping weight distribution optimal.

While some riders love the bold, in-your-face styling, others find it a bit too flashy. The build quality is solid, though some plastic panels could feel more premium compared to rivals like the TVS Apache RR 310, which boasts better fit and finish.

Engine and Performance

At the heart of the KTM RC 390 lies a 373.3cc single-cylinder, liquid-cooled engine that delivers a thrilling 43.5 PS (42.9 bhp) at 9,000 rpm and 37 Nm of torque at 7,000 rpm. Paired with a 6-speed gearbox and a slipper clutch, this engine is a gem for thrill-seekers. The RC 390’s power-to-weight ratio is among the best in its class, making it a rocket off the line.

Performance Breakdown

• Acceleration: The RC 390 sprints from 0-100 km/h in around 5.5 seconds, outpacing the TVS Apache RR 310 and keeping up with the Kawasaki Ninja 400.

• Top Speed: The KTM RC 390 top speed is rated at approximately 170-175 km/h, ideal for track days and spirited highway rides.

• Refinement: The 2022 update improved engine refinement, reducing vibrations compared to earlier models, though some buzziness remains at higher RPMs.

The engine’s mid-range grunt is particularly impressive, allowing effortless overtaking on highways. However, it’s not as smooth as the Yamaha R3’s twin-cylinder engine, which offers a more refined power delivery.

Ride Quality and Handling

The KTM RC 390 is built for corner-carving enthusiasts. Its lightweight trellis chassis (weighing just 172 kg) and aggressive riding posture make it a dream to flick through twisty roads. The bike’s handling is razor-sharp, thanks to its low center of gravity and well-tuned suspension.

Suspension Setup

• Front: WP Apex 43mm USD forks with 125mm travel, offering precise feedback.

• Rear: WP Apex monoshock with 150mm travel, adjustable for preload.

The suspension is on the stiffer side, which is perfect for track riding but can feel harsh on rough roads. Compared to the TVS Apache RR 310, which offers adjustable suspension in its BTO variants, the RC 390’s setup is less versatile but still excellent for aggressive riding.

The RC 390’s ergonomics have been refined in recent years. The clip-on handlebars are slightly raised, and the seat height of 830mm makes it more accessible than before. However, the committed riding posture may cause wrist and back strain during long rides, making it less ideal for touring compared to the Apache RR 310.

Brakes, Suspension, and Tyres

Safety and control are paramount in a sportbike, and the KTM RC 390 doesn’t disappoint. Its braking system is top-notch, offering excellent stopping power and feedback.

Braking System

• Front: 320mm disc with a Bybre radial caliper and cornering ABS.

• Rear: 230mm disc with a floating caliper.

• ABS: Dual-channel ABS with a supermoto mode that disables rear-wheel ABS for more control during aggressive riding.

The Metzeler M5 tyres provide superb grip, especially in dry conditions, though the Michelin Road 5 tyres on the Apache RR 310 offer slightly better performance in wet conditions.

Key Features and Technology

The KTM RC 390 is packed with features that make it a standout in the sub-400cc segment. The 2022 update introduced a host of electronic rider aids, bringing it closer to premium superbikes.

Notable Features

• TFT Display: A full-color, Bluetooth-enabled TFT dashboard with navigation and call/SMS alerts.

• Quickshifter+: Allows clutchless upshifts and downshifts for seamless gear changes.

• Traction Control: Enhances safety during aggressive riding.

• Riding Modes: Switch between Sport and Street modes for tailored performance.

• Adjustable Levers: Customizable for different hand sizes, improving comfort.

While the RC 390’s tech suite is impressive, it lacks the adjustable suspension found on some TVS Apache RR 310 variants and the smoother twin-cylinder engine of the Yamaha R3.

KTM RC 390 vs Competitors

The sub-400cc supersport segment is fiercely competitive, with the Yamaha R3, TVS Apache RR 310, and Kawasaki Ninja 400 vying for attention. Here’s how the RC 390 stacks up:

Comparison Table: KTM RC 390 vs Yamaha R3 vs TVS Apache RR 310 vs Kawasaki Ninja 400

KTM RC 390 vs Yamaha R3

The Yamaha R3 offers a smoother twin-cylinder engine and a more refined ride, making it ideal for long-distance cruising. However, it lacks advanced features like a quickshifter and traction control, and its ₹4.65 lakh price tag makes it significantly more expensive. The RC 390 is the better choice for riders prioritizing raw performance and track-focused dynamics.

KTM RC 390 vs TVS Apache RR 310

The TVS Apache RR 310 is a strong rival, offering better mileage (30-34 kmpl), adjustable suspension (in BTO variants), and a lower starting price of ₹2.75 lakh. It’s more comfortable for daily commuting and touring, but it falls short of the RC 390’s outright performance and handling precision. The RC 390 is the pick for riders who want a pure sportbike experience.

KTM RC 390 vs Kawasaki Ninja 400

The Kawasaki Ninja 400 boasts a larger 399cc twin-cylinder engine with a higher top speed (190 km/h) and smoother power delivery. However, its ₹5.24 lakh price tag and lack of advanced electronics like traction control make it less value-packed than the RC 390. The Ninja 400 is better suited for riders who prioritize comfort and refinement over aggressive handling.

Pros and Cons of the KTM RC 390

Pros

• Thrilling Performance: The 373.3cc engine delivers class-leading power and torque.

• Build Quality: Some plastic panels feel less premium than competitors like the Apache RR 310.

Real-World Mileage and Fuel Efficiency

The KTM RC 390 mileage is claimed to be between 25-29 kmpl, depending on riding conditions. In real-world scenarios, expect around 24-26 kmpl in city traffic and 27-29 kmpl on highways with moderate throttle inputs. Compared to the TVS Apache RR 310 (30-34 kmpl), the RC 390 is less fuel-efficient, primarily due to its larger engine and performance-oriented tuning. The 13.7-liter fuel tank provides a decent range of around 300-350 km, making it suitable for weekend getaways but not as efficient as the Apache for daily commuting.

Who Should Buy the KTM RC 390?

The KTM RC 390 is perfect for:

• Enthusiast Riders: Those who love aggressive riding and track days.

• Upgrading Beginners: Riders moving up from 150-250cc bikes looking for more power.

It’s less ideal for:

• Long-Distance Tourers: The aggressive posture and stiff suspension make it less comfortable for extended trips.
