just checking up on some kx manuals , i know from 91 to 03 all had the 220 mm front rotors ,with the floating disc come out in 92 on the front , not sure if the hub bolt pattern the same but that only a matter checking part numbers , these 220 rotors could of come out even earlier , the first kx only had 210 mm rotors dont know when they went to 220, the 04 kx250 went to 250mm than the front hubs change to a larger bolt pattern from 06 onwards than kawi went to the 270mm for 15 models , i know it hard to get 270 mm oversize for the pre 06 hub , there out there but not what i want , i was chasing one for my kdx 200 h no luck so getting a custom one done in 420 ss , they start of with a 270mm blank and water jet cut it to your desire , you can buy the brackets separate , the kdx uses a larger bolt with a different shaped head, bolt pattern the same as pre 06. getting of the track here but it might help others?
