The 2018 Yamaha Serow XT250 and the 2018 Tricker XG250 dual-sport motorcycles have just been released in Japan. Visually, the two bikes don't seem to have changed very much from their previous incarnations, save for subtle aesthetic tweaks. However, they do get a bit more power and improved fuel economy, while meeting stricter emission regulations.
