If you can partially rotate the engine then the pistons are not seized. If the timing chain has broken then you will probably have bent a valve(s) so that it sticks down. Seems unlikely that a timing chain would have broken though. mmm ????

Best to remove the spark plugs when checking for smooth rotation.

its hard to try to diagnose a problem over the net, but i think you might be getting abit carried away, with seized engine etc, its probaly somthing more simple

did you check the clutch, sidstand & kill switch

If the bike was running ok last time it was used then I'd suggest engine wise you'll be fine. You've checked/charged/replaced battery and no joy
I'd look at the -ve connections (especially any that go to chassis) as well as +ve, may be corroded, or even a defective motor/solenoid
HTH.

If Big_G is correct in stating that the engine rotates partially and then blocks then it is being stopped by something mechanical and not by any electrical fault. That is not being carried away it's just plain logic.

I have checked the Starter motor and checked the current being pulled by it via a tong tester. ( clamp meter ) about 10 amps checked the return wires and belled out wire form soleniod to motor. Also belled out return wire to chasie this is at about 1.25 of ohms.

Can you explain in more detail what happens.

For example. When you hit the starter button, does anything happen at all Does the starter solenoid click like it should

For your information.

Battery Voltage State of Charge
12.60+ 100%
12.50 90%
12.42 80%
12.32 70%
12.20 60%
12.06 50%
11.90 40%
11.75 30%
11.58 20%

As you can see, 11.5 Volts is just about a flat battery. Even jumping from a car battery is possibly not going to work.

Have you actually charged the battery again or just jumped from the car battery

The more explanation you can give will help everyone diagnose the fault. I doubt your problem is unique and will more than likely already have been covered and diagnosed before on this forum. Information is the key.
