The Yamaha Lander 250 is a motorcycle model manufactured by Yamaha Motor Company. However, as of my knowledge cutoff in September 2021, Yamaha had not released a Lander 250 model. It's possible that Yamaha has introduced a new Lander 250 model since then or in the future. It's always best to refer to Yamaha's official website or contact a Yamaha dealership for the most up-to-date and accurate information about their motorcycle models.
