Yeah, looks a bit suspicious!

Still looks to have a strong family resemblance to the Yamaha YDS3 from about 66. I went for a nice ride on one in the tropics - keeping an eye out for water buffalo... The YDS3 has/had the chain on the right.

I think the picture is trasposed. Seems like the clutch cable is coming off the right hand lever.

Edit; nope, the writing on her wet suit is the right way round.

YDS2/YDS3 never had a fully enclosed chain. And the headlamp is worngA , they had a sort of binnacle on top.

I thgink it's smaller than 250. Def a two smoker twin, probably Yamaha

researching, researching

Searched everything I have and still no closer to I'd-ing this bike

I wonder where the photo was taken and whether it's one of those obscure Asia-only models? Like you, I can't get a match as there are parts of the bike (fully enclosed chainguard with fork gaiters)which don't seem to go with other parts if we're guessing an early Yamaha so maybe it's a bitsa!

It's got one spark plug. In the middle of the head. It's a single.

Yamaha YA125.

Plus the YA is a semi-cylinder forward design.
Despite the central plug, I still think those fins and crankcase are too wide for a single cylinder.

Ever seen an MZ, ETZ250? Externally, the motor looks like a 600 single.

Dunno if I'm convinced it's a two smoke yet. Looking again now...

Edit; definately a two stroke single. The pipe appears to come from the side, but looking closer it comes out scewiff from the barrel.

As to what it is, still non-plussed.

Yeah, have seen the ETZ's. They have quite a square looking barrel and fins.
This has vertical cooling fins on top.
No, I'm convinced that the enclosed chain is Yamaha type, as to what it is

Definitely going to go through my classic Yamaha book tonight as this is bugging me now !!
