Could anyone identify this bike

[hocko]

Possibly an early Bridgestone 125 twin, late 60's. Are there any identifiers on the frame or engine?

Cheers

I think we've already identified it (a Yamaha YAS1, although it would help if people didn't post the same message in different sections).

That's a Yamaha YAS1 125cc twin.  It could also be a Yamaha YCS1 which is the 180cc twin, they look alike.  Near the exhaust port will say what cc,s the engine is for both cylinders. Can't be a Bridgestone because it doesn't have rotary valves.
