I guess being my second year owning a bike. Will I notice a difference between a $6,000 CRF250X and a $2500.00 KDX 200/220. I will probably dump this bike 100 times over the coming year. How about an older 200? 1986 $1300 US asking price. Ad says good condition well maintained fast and fun. I would prefer a newer bike, what wears out on these bikes in the way of seals, gaskets, etc. 1986 bike probably needs - fork seals, rear shock?
