My first bike was a 2005 CG125 and at the time, I loved it.
No story as such but finding it for sale ended up being the push I needed not to quit after an awful CBT experience.
Rode it 3 months after passing my test and getting the CBR and I hated it, so sold it. I will always love it as my first bike though.
First (and currently only) big bike, my CBR - I LOVE this bike although sometimes she doesn't love me back!
