    The Vehicle Identification Number (VIN) is composed of 17 characters. The standard was originally defined in ISO Standard 3779 in February of 1977. Then it was revised in 1983. The ISO VIN is designed to identify motor vehicles of all kinds: cars, trucks, busses, motorcycles etc.

    The Vehicle Identification Number (VIN) contains three major sections:

    * WMI - World Manufacturer Identifier (1,2,3 characters in VIN structure) If the manufacturer builds less than 500 vehicles per year than the third digit is "9". The WMI is described in detail in ISO 3780.
    * VDS - Vehicle Description Section. It contains 6 characters (4th to 9th positions in VIN) and defines vehicle attributes specified by manufacturer.
    * VIS - Vehicle Identifier Section. The last 8 characters of VIN define Year, manufacturer plant and serial (sequential) number of the vehicle.

    The last four characters shall be numeric. The 10th position of the Vehicle Identification Number is a YEAR CODE.

    ISO recommends that in VIN code capital letters A to Z and numbers 1 to 0 may be used, excluding I,O and Q in order to avoid mistakes of misread. No signs and spaces are allowed in Vehicle Identification Number code.
    ***********************************************

    Recap with examples:

    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 (8), Buick (4), Cadillac (6), Chevrolet (1), Chrysler (C), Dodge (8), 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 (8), 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(8), 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
