The Activa 125 features a 124.9cc engine that makes 8.7PS and 10.12Nm of torque. Honda has managed this increase in displacement by increasing the bore and stroke dimensions of the smaller 110cc engine. The bottom end as well as the CVT system is identical to the smaller Activa. With these small changes it comes as no surprise then that the Activa 125 feels similar to the 110 when youre riding it too. The refined engine feels very smooth just like its sibling, so smooth in fact that you cant tell if the increase in displacement has brought about any change in urgency when you twist the throttle. The 0-60kmph time has dropped below 10 seconds and the 125 hits 70kmph with the same effort that the 110 reaches 60kmph. Top speed is marginally higher as well. The 125 returned 53.3kmpl in the city and 67.4kmpl on the highway for a combined figure of 57.9 which is only 0.6kmpl down on the Activa 110.
