Honda activa 4G is really a fourth generation vehicle. My sister bought it a week ago it have same body like activa 3G scooty I like this scooty because it’s speed is better than the activa 3G .in the case of milege both activa 3G and 4G are about same in my opinion if you searching for a free open mind bike then this activa 4G is only for you.it’s cost is less more than activa 3G
