Harley-Davidson has had to suspend production of its all-electric LiveWire motorcycle due to a charging problem. The company is currently investigating the issue and running tests in order to better understand the issue.

According to Fox Business, Harley asked its customers and dealers to only use a professional type of charger that’s available from dealerships, rather than basic home electrical outlets. As of right now, there is no word on when production is expected to resume.

While LiveWire owners have been able to charge their bikes using standard wall outlets, that type of charge can take as much as 10 hours, whereas Harley’s own charging stations can juice up the battery in just one hour.

The company also told TechCrunch that it will not be recalling any LiveWire motorcycles currently on the road, but simply halting production and deliveries on brand new models.

“We recently discovered a non-standard condition during a final quality check; stopped production and deliveries; and began additional testing and analysis, which is progressing well”, Harley stated. “We are in close contact with our LiveWire dealers and customers and have assured them they can continue to ride LiveWire motorcycles. As usual, we’re keeping high quality as our top priority.”

The electric motorcycle went into production earlier this year, with deliveries to dealers commencing only a few weeks ago. Its purpose has been to help rejuvenate sales for the Wisconsin-based company, while also complementing its well established internal-combustion-engined models.
