So I bought a 2001 kx125 the other day n started to shop for some parts. I noticed that the plastics on my bike are the late 90s style. Ive only been able to find a couple bikes online that are the same year and plastics as mine, all of the other 2001s have a newer style body. The vin and everything else checks out as a 2001. Are the plastics interchangeable?
