The item "Starter chain Active" is a starter drive chain for Active mopeds. The chain transmits rotation from the electric starter to the engine to spin the crankshaft when starting.
If the starter spins but the engine does not turn over, or you hear a clanking noise when starting, check the chain: it may have stretched or broken. Manufacturer: TATA; country: China. Install the part with clean mating surfaces and, where possible, with new gaskets and fasteners.
