this Kawi KDX250 is a good bike. robust, good power,well built.nice looking. I need help on dating it though. I called a dealertolfthem the serial number? they said it was an 83, so Ok. But Ive seen 83 175's and 400. 420's that have different print on the seat. the one on mine IE,. say's solid 250 on it. buttt, the one's ive seen have the Nice looking open block letter KDX on them. Ive looked on bikepics & cycle chaos, and I see a 250 on there but with my seat saying 250 in the solid block number's. I was thinking that when a company did a series of bike's ? they would have them looking all the same in thier different size's. i was wishing that mine had the open block letter's on it. as it would look really nice, and i think alot beter than that kind of chincy looking solid 250 on there.
