    RX series model identification sequence

    Hi all,

    I was in the process of trying to collate the Engine/chassis number sequence for RX series bikes...

    This will allow us to find the genuine bikes over the converts (4-speed to 5-speed for eg).

    All engine numbers will start with a 3 character model identification code

    As for as I know the sequence is this:

    RD350 HT IAI.51.xxxx
    RD350 LT 00xxxx
    RX100 1L1.xxxxx
    RXG & RX135 1L3.xxxxx
    RXZ 4-speed 1L5.xxxxx
    RX135 5-speed 1L7.xxxxx
    RXZ 5-speed 1L9.xxxxx
    RXZ 5-speed (2003) 4UU.xxxxx
    RX135 4-sp catcon ?????????


    Please advise on any errors ....

    Also why the difference in the RXZ 5-speed bikes ....

    My RXZ 5-speed has 4UU.xxxxx it also has a restrictor at the air filter which my mech says he has never seen before on a 5-speed..

    Any inputs will be appreciated.

          Sir, very nice information about the RX series. My bike is 1998 RX135 4S, it has the serial number as 1L5xxxxx

          May be RXG might have come with 1L3? I'm not sure.

                      why some RX100 have 6 digit and some have 5 digit chassis number?

                          The RXG was launched in March 1996.

                          It could be that the last batch of RX100 got the 1L5 chassis. But Yamaha is not usually so careless.

                          Is your RX100 registered after March 1996?

                          Also what's the engine number. If that isn't 1L1, it's most likely a conversion to RX100 by an enthusiast.

                          Try talking to previous owners of the bike. Maybe they can shed some light.
