The number on the steering head makes no sense. It's not a valid VIN.

All KX VIN will start out as JKAKX

For example my 2001 Kawasaki KX500's VIN is JKAKXVEC11A030036

Here how a motorcycle VIN is broken down. There is a detailed method to all the numbers and letters. This example is for a Suzuki, but Kawi follows in the similar details:

Digits 1,2,3 are World, Manufacturer, Identifier
Digits 4,5,6,7,8 are Vehicle descriptor Section -- *Somewhat variable based on manufacturer.
Digit 9 is the check digit
Digit 10 is the Year code
Digit 11 is the Factory code
Digits 12,13,14,15,16,17 are the Vehicle Identification Sequence


Let's see how this splits:



First digit - Country code
U.S.A.(1 or 4), Canada (2), Mexico (3), Japan (J), Korea (K), England (S), Germany (W), Italy (Z)

Second digit - Manufacturer
Audi (A), BMW (B), Buick (4), Cadillac (6), Chevrolet (1), Chrysler (C), Dodge (B), Ford (F), GM Canada (7), General Motors (G), Honda (H), Jaguar (A), Lincoln (L), Mercedes Benz (D), Mercury (M), Nissan (N), Oldsmobile (3), Pontiac (2 or 5), Plymouth (P), Saturn (8 ), Toyota (T), Volvo (V), Suzuki (S), Kawasaki (K).

Third digit - Identifier
Motorcycle (1 or A) Kawasaki and Suzuki seem to follow this anyway

Fourth digit - Vehicle category
Data here is Suzuki specific, haven't found info for other brands.
Scooter (C), Business model or commuter (B), Single cylinder sport/street (N), Multiple cylinder sport/street (G), Family (F), Off road (S), V-Type engine, street, V2/V4/V6/8,... (V), Square Four (H)

Fifth digit - Engine Displacement
Data here is Suzuki specific, haven't found info for other brands.
A=49cc and less
B=50-69cc
C=70-79cc
D=80-89cc
E=90-99cc
F=100-124cc
G=125-149cc
H=150-199cc
J=200-249cc
K=250-399cc
M=400-499cc
N=500-599cc
P=600-699cc
R=700-749cc
S=750-849cc
T=850-999cc
U=1000-1099cc
V=1100-1199cc
W=1200-1299cc
Y=1400-1499cc
Z=1500 & up

Sixth digit - Engine Type
Data here is Suzuki specific, haven't found info for other brands.
1=2 stroke single
2=2 stroke twin
3=2 stroke triple or four
4=4 stroke single
5=4 stroke twin
6=?
7=4 stroke four

Seventh digit
Data here is Suzuki specific, haven't found info for other brands.
Design sequence or model version first version uses 1 then second version uses 2 etc... the tenth version would then be identified by the letter A then B etc..

Eigth digit
Data here is Suzuki specific, haven't found info for other brands.
First version uses 1 then second version uses 2 etc... the tenth version would then be identified by the letter A then B etc...

Ninth digit - Check digit
The ninth vehicle identification number digit is a VIN accuracy check digit, verifying the previous VIN numbers. This is how the check digit works


STEP 1
Assign to each number in the VIN its actual mathematical value and assign to each letter the value specified for it in the following chart:
ASSIGNED VALUES:
A=1 G=7 P=7 X=7
B=2 H=8 R=9 Y=8
C=3 J=1 S=2 Z=9
D=4 K=2 T=3
E=5 M=3 U=4
F=6 N=4 V=5


STEP 2
Multiply the assigned value for each character in the VIN by the position weight factor specified in the following chart:
VIN POSITION AND WEIGHT FACTOR:
1st = 8 10th = 9
2nd = 7 11th = 8
3rd = 6 12th = 7
4th = 5 13th = 6
5th = 4 14th = 5
6th = 3 15th = 4
7th = 2 16th = 3
8th = 10 17th = 2
9th = check digit

STEP 3
Add the products from steps 1 and 2 and divide the total by 11.

STEP 4
The numerical remainder is the check digit which would appear in the 9th position in the VIN. If the remainder is 10, then the letter "X" is used for the check digit.


Tenth digit - Year Code
80(A), 81(B), 82(C), 83(D), 84(E),
85(F), 86(G), 87(H), 88(J), 89(K),
90(L), 91(M), 92(N), 93(P), 94(R),
95(S), 96(T), 97(V), 98(W), 99(X),
00(Y), 01(1), 02(2), 03(3), 04(4),
05(5), 06(6), 07(7), 08(8 ), 09(9) ( Don't know what happens after that )

Eleventh digit - Factory Code
Manufacturer code for what plant it was built in

Twelfth to Seventeenth digits - Serial Number

Well, that was more of a comment on the 1990 KX125 had silver forks and 1991 - 1993 had blue forks. If he is in Europe, then they had the USD forks on the KX's in 1989, whereas the USD forks weren't available on the USA models until 1990.

The KX125H means 1990 or 1991. With it being 9,000+ on the last four digits, I am thinking it is a 1991 model.

Congratulations on having a KDX250! I like 'em!

It could be a bike imported privately from Japan, as was the case with my 95 kx250. It has a similar number on the neck. I emailed Kawasaki Australia with the number and they replied with the correct year model, and told me how it was imported.
So shoot your country kawasaki an email, or try Australia's, they are very helpful. Good Luck
