Top 400cc Performance Motorcycles to Watch in 2025

Remember the high-revving, sonorous small-displacement four-cylinder engines that defined an era? They seemed to have faded into history—until now. A quiet revival of compact sport bikes is underway, with manufacturers reintroducing 400cc-class motorcycles to reignite the passion for speed and agility. But which models truly dominate this segment, and which ones deserve your anticipation?

Here, we spotlight eight of the most compelling 400cc motorcycles arriving in 2025, from Kawasaki’s nostalgic revival to Triumph’s British sophistication and KTM’s track-ready machines.

The Ninja ZX-4RR stands as one of the most talked-about small-displacement sport bikes in years. Inheriting the DNA of Indonesia’s ZX-25R, it rekindles hope for riders mourning the decline of high-revving four-cylinder engines. At its core lies a compact 399cc DOHC inline-four, blending speed, power, and cutting-edge technology—a rarity in the 400cc class.

For 2025, Kawasaki focuses on cosmetic updates, retaining the 2023–2024 model’s engine, chassis, suspension, and electronics. Buyers can choose between two liveries: the eye-catching KRT Edition (inspired by the ZX-10R WSBK’s yellow-and-black scheme) or the subdued SE variant in silver and black.

The ZX-4RR’s pièce de résistance is its high-strung engine, delivering adrenaline-pumping performance. Advanced electronics—including traction control and ride modes—further sharpen its handling and safety. For riders chasing uncompromising thrills, this is the machine to beat.

Emerging as a dark horse, the Kove 450RR enters the fiercely competitive small-displacement multi-cylinder arena with a bold proposition. Its unique power delivery, lightweight design, and aggressive pricing position it as a legitimate challenger to Kawasaki’s ZX-4RR.

The 2025 iteration features redesigned side fairings and optimized upper vents, while mechanical components carry over unchanged. The 450RR’s edge lies in its pared-down weight, achieved through strategic material choices and structural refinements—translating to sharper acceleration and agility. Coupled with its value-driven pricing, this bike appeals to performance seekers on a budget.

If the Ninja 300 set a high bar, the Ninja 400 vaults over it. Redefining what a 400cc sport bike can offer in performance, style, and value, it remains nearly peerless in its class.

The 2025 model introduces fresh color schemes for the Japanese market, including metallic matte graphite gray and metallic flat spark black (replacing the signature lime green). Mechanically identical to its predecessor, the Ninja 400 continues to strike a balance between approachable handling and spirited performance, making it ideal for both commuting and weekend rides.

Kawasaki’s naked Z400 exemplifies the brand’s push to cater to diverse rider preferences. From a single Z1000 offering in 2015 to six models spanning 125cc to 900cc today, the lineup has expanded dramatically.

The 2025 Z400 receives a metallic spark black and metallic moon dust gray paint job, accented by a lime-green frame. Unchanged mechanically, it remains a nimble city companion with a comfortable upright posture—equally suited to daily commutes and longer jaunts.

The RC 390 has earned its reputation as one of the finest entry-level sport bikes, thanks to a punchy single-cylinder engine and razor-sharp handling. Lightweight, affordable ($5,799 starting price), and track-capable, it’s a beginner’s dream that doesn’t compromise on excitement.

KTM is refining the 2025 RC 390, expected to adopt Moto3/RC 8C-inspired styling—think single-pod fairing, bubble windscreen, and revised headlights. For riders craving track-day thrills without breaking the bank, this remains a top contender.

Triumph’s 2025 Speed 400 emerges as the star of its refreshed small-displacement range (alongside the Scrambler 400 X and XC). Tailored for paved roads, it combines classic aesthetics with contemporary upgrades.

New for 2025: improved seat cushioning, adjustable brake/clutch levers, and sturdier Vredestein tires. The Speed 400’s timeless design and refined ride make it a standout for riders valuing style and substance.

Breaking from its dirt-bike heritage, Husqvarna’s Svartpilen 401 proves the brand can master city streets. The 2025 model extends its wheelbase for stability and lowers the seat height to 805mm (31.7 inches), enhancing low-speed confidence.

With minimalist Scandinavian styling and agile handling, the Svartpilen 401 is a compelling choice for urban riders seeking individuality.

The 390 Duke has always punched above its weight. For 2024, KTM overhauled 90% of the bike while preserving its rebellious character. The 2025 version retains its potent mechanics but adds comfort and tech refinements, solidifying its status as a streetfighter with soul.
