The 250cc sportbike segment is becoming more exciting than ever, especially with four-cylinder machines now available at competitive prices. Two standout bikes in this category are the Kawasaki Ninja ZX-25R and the QJMotor SRK250RD. Both feature fully-faired designs and inline-four engines, but their philosophy and target riders differ greatly.
The ZX-25R emphasizes top-end thrill, track-inspired performance, and advanced electronics, while the SRK250RD focuses on approachable high-rev fun, user-friendly handling, and everyday usability. Therefore, it’s worth exploring how these two machines compare in terms of engine, features, riding comfort, and overall suitability.

Engine and Performance
Kawasaki Ninja ZX-25R

As a result, the ZX-25R is most exciting when ridden aggressively, especially at high RPMs, making it a dream for performance-focused enthusiasts.
QJMotor SRK250RD
Similarly, the QJMotor SRK250RD also features an inline-four 249cc engine, putting it in the same high-revving category. While it produces slightly less peak power than the ZX-25R, the SRK250RD offers smooth, predictable power delivery, making it easier to control in city traffic or on longer rides. Therefore, riders enjoy the fun of a four-cylinder sportbike without being overwhelmed, which is ideal for those who want excitement but also practicality.
Both bikes deliver distinct experiences: the ZX-25R thrills at the top-end, whereas the SRK250RD balances high-rev fun with daily usability, giving riders confidence in all scenarios.
