Engine loses some power
The new 2025 ZX-25R has undergone performance adjustments:
Maximum power changed from 35 kW (48 hp) at 15,500 rpm to 34 kW (46 hp) at 16,000 rpm
Torque decreased from 22 Nm to 21 Nm, both at 12,500 rpm
According to Kawasaki, the claimed fuel consumption is 25.1 km/l at a constant 60 km/h and 18.1 km/l under WMTC conditions.
RR version with premium suspension
The ZX-25RR version is equipped with a Showa BFRC-lite rear shock absorber, the same type used in the brand’s high-performance models. It also features exclusive graphics with the “RR” logo and a clear windshield. The SE version retains a more conventional look but includes premium finishes and a digital TFT display.
Both bikes are compatible with the RIDEOLOGY THE APP MOTORCYCLE, allowing voice commands and navigation via smartphone. Upon purchase, customers receive a QR code that provides one year of free access to the app’s features.
