I have a 1990, KX 500. Great play bike and runs very well. I want to start riding the vet motorcross class and maybe some sportsman supermotard. I have been offered $1,500 for my bike and I have seen several good condition post 1996 KX's (a 1997 and a 1999) for $2,500.
But here is the question, do I spend the $1,000 difference on buying a post-1996 bike or do I use the money to modify my 1990 (suspension revalve, V-force reed, etc.). Are the performance improvement on a post-1996 KX that important to a non-pro rider? Thanks guys....
