Honda-SOHC

Hello everyone! im very new to the community and I just begun a few months ago riding motorcycle, so im a real newbie to all this, getting the hang of it. I bought a Honda CB1X 125, 2015, and I just wanted to ask you maybe if you guys could shed some light on wether this motorcycle is upgradable in any way, suspension, motor, etc, or if it would be better to buy a completely new motorcycle? I will strap a dog cage to the back of the motorcycle and 2 side bags for my tools and stuff, I understand I will go really slow driving up a hill, but im to pumped to care about going slow jaja all I like is moving freely.

I will attach a generic photograph of my bike because its literally the same!
And a photo of the cage I will strap on, I found the idea on the internet.
