Hello. I would like to put an original handlebar on my Kawa Z400J (bj. 1981), but I don’t have any measurements or the like, because there is another handlebar on mine (at that time it was bought). Diameter is 22mm. The search for the original handlebar for the Z400J has been unsuccessful so far. There are always identical parts that were installed on different Kawa models. Does anyone know if there are other Kawa models with the same handlebar on it as the Z400J? Or maybe jema And the exact dimensions, part number or the like of the original handlebar? Thank you in advance
