Harley-Davidson has halted production of its new electric LiveWire motorcycle after finding a problem during quality control tests. In a statement, the company said it “recently discovered a non-standard condition during a final quality check” of the first motorcycles. The Wall Street Journal says the problem relates to the vehicle’s power charging system. Harvey-Davidson announced on Monday that it had begun additional testing. It said the tests were progressing well, but did not say when the LiveWire’s production might restart. The company also announced it has halted shipments of the motorcycle to Harley dealerships. The Reuters news agency says the company had begun shipping the cycles to dealers in late September. The fully electric LiveWire is seen as an attempt by Harley to appeal to a new generation of young, environment-friendly riders.
