This "WR450F" was a bike made to have "easy handling engine characteristics", "quick rotaionality", and "easy set-up characteristics". It had an innovative appearance.
It was the smallest model of the GS series that inherited the design of KATANA. It came with a stylish bikini cowl and a cost-effective 4-stroke single engine.
It was the series model of the 200. It was a full-scale model that incorporated the technologies of its base model, motocrosser KX125, and the enduro mechanism.
It mounted a KE125-based engine that was equipped with a 6-speed transmission. It was highly practicable, for it came with parts such as a large tank, a thick seat, or a rear compartment.
Though the movement of high output bikes of small engine displacement volumes tend to become peaky, this model solved that problem by adopting an exhaust device called SAEC
It was the smallest model of the GN series that took advantage of the light ride feel and the cost performance of the single engine. Same as 250, it adopted the newly designed cast wheel.
It made its debut in 1974 as the new 125cc twin engine road sport bike since WOLFT125. MY77 model, which had a new color graphic design, was its final model.
