DRB brand Dirt Bike

[DAB]

Hi.. I'm new to this forum.
I just acquired a Chinese dirt bike with a 125 CC with vertical piston type like a Honda GC engine.

I am having a hard time finding any information on it. Has anyone come across the DRB brand before?
It's been neglected but has had little use. It does run after sitting for years. Just was hoping to find info on the brand.

Thanks.
