1998 Kawasaki KX250
A very fast MX racer with low quality
Fork seals blew in the first 3 months.
I had to replace them every 2 - 3 months after as well.
I rebuilt the motor after 2 seasons and discovered that the cylinder was worn out. I later saw in a mag that the KX 250 was infamous for bad cylinders. Replacement cost was $550, plus the cost of the piston, rings, gaskets, etc.
I purchased this motocross bike brand new and loved everything about it. The power, layout, and handling were all excellent.
After two seasons on it, with only four or five races run, I decided to rebuild the motor as a preventative measure. I discover that the cylinder walls had worn out, which I later learned is common with this year of KX 250's. The dealers would not warranty this.
Worst brakes in the class.
My dealer was however very helpful with setup, and regular maintenance.
My last Honda CR 125 lasted for 4 years with nothing major going wrong with it. I worked on this bike to keep it running all the time.
Would you buy another motorcycle from this manufacturer? No

Motocross bikes, such as your KX250, are higher maintenance than say a 4 stroke trail bike such as an XR250. It is not uncommon for 2 stroke motocross riders to have to do the top end twice in a year, depending on how hard and often they ride.
The cylinders can be re-plated at Eric Gorr. If you check your top end before it self destructs, there will be less damage and cost to do the top end. I believe it is unrealistic to expect a motocross bike top end to last longer than a year if it is being ridden hard or raced.
