The Indian sportbike scene has never been more exciting, and 2025 is shaping up to raise the bar even higher. Two names dominating the track-focused entry-level performance space right now are the Kawasaki Ninja ZX-4RR and the KTM RC 390. Both bikes offer aggressive styling, cutting-edge hardware, and race-bred DNA—but they cater to very different kinds of riders.
With performance enthusiasts looking for the best bang-for-buck machine for the track and twisties, the ZX-4RR vs RC 390 debate is heating up fast.
Let’s take a closer look at how these two machines stack up for Indian riders.
Engine and Performance – Twin vs Single Drama
The most glaring difference is under the fairing. The Kawasaki Ninja ZX-4RR brings in a rare four-cylinder 399cc engine—something unheard of in this segment. Producing around 75 PS (with RAM air), it screams all the way to nearly 15,000 RPM. This gives it a unique feel, more akin to a mini supersport like its elder ZX-6R sibling.
On the other hand, the KTM RC 390 sports a 373cc single-cylinder engine that pumps out about 43.5 PS. While it may lack the top-end madness of the ZX-4RR, it compensates with brutal mid-range torque and lighter overall weight. This makes the RC 390 immensely usable for Indian road conditions and also potent on shorter circuits.
Verdict: The ZX-4RR is the more thrilling engine on paper and on track, but the RC 390 feels more accessible for everyday riders and offers strong punch where it counts.
Chassis and Handling – Precision vs Agility
Both machines are purpose-built for performance. The ZX-4RR uses a high-tensile steel trellis frame and comes with fully adjustable Showa suspension, including a rear BFRC-lite shock and USD forks upfront. It’s been tuned with track use in mind, especially for corner stability and high-speed control.
The RC 390, meanwhile, also features a lightweight trellis frame and WP Apex USD forks. It’s agile, flickable, and feels razor-sharp in tight corners, making it very rewarding on technical tracks like Kari Motor Speedway or short hill runs.
Verdict: The ZX-4RR is more planted and composed at high speeds, while the RC 390 wins on maneuverability and low-speed agility.
Electronics and Features – Tech Loaded Duo
Kawasaki hasn’t held back on the ZX-4RR. It features a 4.3-inch TFT display, riding modes, traction control, quickshifter, and even launch control. It’s a superbike-level electronics suite in a sub-400cc body.
The RC 390 is no slouch either. KTM gives it a full-color TFT, cornering ABS, Supermoto mode, quickshifter, and ride-by-wire throttle. However, it lacks some of the high-end adjustability and track-focused tools the ZX-4RR offers.
Verdict: The ZX-4RR pulls ahead for serious riders who want more control on track, while the RC 390 delivers exceptional value with essential tech.
Pricing and Availability in India
As of now, the KTM RC 390 is available across India with a price tag around ₹3.18 lakh (ex-showroom). It’s locally manufactured and widely supported by KTM service centers.
The Kawasaki Ninja ZX-4RR, on the other hand, is expected to arrive via CBU route or in limited numbers, likely priced north of ₹8 lakh (ex-showroom). That makes it nearly triple the cost of the KTM.
Verdict: The RC 390 remains the value-for-money performance king. The ZX-4RR is a dream machine, but affordability might keep it exclusive to a niche group.
Final Thoughts – Which One Should You Choose?
If your weekend plans include racetracks and you crave the spine-tingling scream of a high-revving inline-four, the Kawasaki Ninja ZX-4RR is a dream come true. It’s engineered for serious riders looking to hone their skills at a competitive level.
But if you’re a daily rider who also enjoys occasional track sessions and backroad fun, the KTM RC 390 is more practical, cost-effective, and still an absolute riot to ride.
Ultimately, both bikes cater to different ends of the sportbike spectrum. One is exotic and track-pure, the other is sharp, street-friendly, and well within reach of the Indian enthusiast.
