Motorbike question

[DaveL485]

I have a 125cc Motorini bike, one of the cheapo chinese things (2016 Motorini Bomber 125).

I was riding it the other night and it just conked as I was sat at some lights, cut out like id hit the kill switch. Wouldnt start and wont even fire. Its got no spark. Ive replaced the coil pack & lead, and also the CDI, but I still have no spark.

I'm proficient with cars but my bike ign system knowledge is limited. What should I look at next? How does the ign trigger work, I can't see a crank position sensor? Battery is new & charged, handlebar controls are all new, whole bike wiring loom is new less than 200 miles ago.

Roadside poke and hope first point of call, would be side stand switch, might have gone open circuit, other than that , meter out and start hunting, I'd check you've got power on low tension side of coil, if not work back , if you have go forward.
Not my usual fodder, but I guess it'll be either a Suzuki GS125 engine copy or a Honda CG125 copy, there's hundreds of different ones of these, every foundry in China must have moulds.

Although .....to correct myself that would only interfere if it was in gear....

Had the wiring break on inside the loom cover on the head stock or rub through and earth out

No idea on what the engine is! Power all seems to be there but the components are flaming hard to test, hence why I bought a new CDI and coil.

Trying to figure out the trigger system, must have a crank angle sensor of sorts?
