Scooter won't start - this issue became progressively worse over time

What I'd do. Jump from a car battery and see how fast it cranks. Check the cables both to the relay and the grounding cables. Check for warm or hot spots on the cable after cranking. Check voltage drop at various points of the starter circuit when cranking. It sounds to me like you need a new battery but other things can cause slow cranking. When the starter is off you can usually tell a good or bad one by the way it "kicks" when you attach jumpers to it from a car battery. You can take the spark plug out and see if it cranks faster to try to eliminate if some thing with the engine/drive train is causing it to crank slow. But I'm think a new battery and good cables will probably solve your problem. Be careful when jumping or cranking excessively with a good battery, you will overheat the starter and ruin it.
