That's a Honda cb125 frame.
I have one sitting in my living room right now, paint stripped ready for primer if you want it. I'd take $50...but not sure how much shipping would be. It's kinda bulky to ship.
I'm located in Brooklyn, NY.
The gas tank was hand made and crap. The seat is a cheapo fiberglass one from ebay. Wheels are stock 1.4" wide 36 spoke honda and stock cb125 disk brake that was mechanical and not hydraulic. The stock small drum brakes could stop better than it, they were purely a marketing thing to say it had a disk.
The builder of this had a thread going on do the ton, or caferacer a year or so ago.
