Just my speculation - Chinese factories want to expand into the world motorcycle market. Nothing they offer can compete with the Indian giant, Royal Enfield.
Meanwhile, the Chinese troops continue to initiate skirmishes at the northern Indian border. India is not putting up with Chinese expansion into India.
Amazon markets Chinese knock offs for just about every product and non-Chinese product. Amazon has probably been informed that the Chinese Communist Party doesn't like RE. In short, Amazon is a marketing front end of Chinese industry.
