i see mxa magazine test new kx250f 17 and claim the new showa sff tac forks will give the kyb sss a run for there money , all stock suspension can be improved , look at the showa air fork , put a spring conversion in it and revalve to suit and it great , and the best thing is it slips straight in a k5 triples clamps , lighter as well, the std k5 forks are ok if you gold valve them to suit your needs with the correct springs for your weight and use skf seals for less friction they will do the job ,
