The output voltage of the motorcycle alternator should be measured when increasing the throttle. For motor models equipped with AC lighting circuits, the AC output must be greater than 25 volts. For motors equipped with DC lighting circuits, the AC output must be greater than 50 volts, otherwise the electricity production will not be sufficient.
Voltage is low at low speed and high at high speed. It all depends on the battery to stabilize the voltage. If it is a set of coils for lighting bulbs and charging, it is about 10 volts. low speed and no load, and over 30 volts at high speed.

Motorcycle engine characteristics
1 The engine is a two- or four-stroke gasoline engine.
2. It adopts air cooling, including natural air cooling and forced air cooling. General models use natural air cooling, which relies on air blowing through the cylinder head and the radiator on the cylinder liner to carry away heat while driving.
In order to ensure engine cooling at low vehicle speeds and before starting, high-power motorcycle engines adopt a forced air cooling method that installs fans and air ducts and uses forced air to blow out the radiator.
3. Engine speed is high, usually above 5,000 rpm. Power per liter (effective power emitted per liter of engine displacement) is important, generally around 60 kW/liter. This shows that the motorcycle engine has a high degree of reinforcement and the engine has a small overall size.
4. The crankcase, clutch and gearbox are designed to be integrated into a compact structure.
