IIRC CBR125 is 12hp and Grom is 8hp. Both 125cc but Grom is down 30% in hp.
I've taken a Grom out into traffic with students while teaching.
Not a huge fan of my helmet being the same level as the bumpers on some of the lifted trucks in my area - RedNeck Central.
And before anyone cracks a short joke, we have instructors that are over 6 ft tall, they also sit just as low on the Grom.
