Having been discontinued in 1991 in favor of the Yamaha XT350, this model was reintroduced in 2008, replacing the Yamaha XT225, due to increased popularity of the 250 cc class.[4] The XT250 is branded the SEROW 250 in Japan. In 2013, the USA XT250 received a fuel-injected engine.

In January 2020, Yamaha Japan released the Serow Final Model, discontinuing the little bike due to increasing emission requirements. This is its final year.[5] Yamaha US has continued the model unchanged.
