I wonder if anyone knows their bikes well enough to know what model it is?
It's quite hard to place that bike, especially with images that small. I can't see any manufacturers names anywhere.
What do we know / can we guess?
Well, it's a single cylinder 4-stroke model. - Likely to be small capacity.
Single front disk / rear drum. - Small capacity, rules out 1970s and much of the early 80s.
Cast wheels. - These didn't generally come in for small bikes until the 80s.
Faired in tank. - Quite modern then.
It looks like someone has had the bars off it, are they clocks or the headlamp hanging down? - Possibly has a bikini fairing
Twin rear shocks. - Cheap or retro
Exhaust pipe shape - Retro, modern bikes normally have pipes that kick up, or are routed around the frame / fairing, that looks 1970s!!!
Without the rear pipe, it reminds me of a Yamaha YBR125, or a Honda CB125F.
The fact there are modern & retro features indicates that it's either customised by the owner, or it's a cheap overseas knock-off of one of the Japanese big four's 125s. I'm going to go with it being a knock-off, so without the manufacturers name, it's going to be nard to narrow it down further.
