We recently purchased one of your motorcycles and have encountered an issue. The battery that came with it has stopped functioning, and we need a replacement. Could you please provide us with a quote for a new battery? We're looking for prompt service since we rely heavily on the motorcycle. Your assistance would be greatly appreciated!
