    Default Differences between DRZ-400 SM, S, & E models.

    I wanted to start a thread on this so that it is easy to access if there are any questions about the differences between the 3 and what parts match and which do not. From what I have learned these are some of the differences and correct me if I am wrong.

    Swing arms
    -Bolt up on all 3 models
    -S and E models do not have a chain guide like the SM models do
    -SM has different caliper mounting than S & E

    Subframe
    -S & SM models are the same (have mounts for fender/racks and are longer)
    -E model is like the S & SM but shorter (no mounts for fender/rack)
    -All 3 will bolt up to any 400 frame

    Rear Brake lever
    -S & SM Models have a tab for a brake switch
    -E Models have no tab for a brake switch
    -All 3 will bolt to any 400 frame

    Engine
    -E models
    -12.2:1 Compression
    -Stage 2 cams
    -Larger Carb
    -S & SM
    -11.3:1
    -Stock Cams
    -Smaller Carb

    Suspention
    -SM has different size triple clamps, larger inverted forks, stiffer rear spring
    -S & E have same size triple clamps, smaller forks, softer rear spring

    This is all I can think of right now and need to get going so correct me if I am worng and please ad any other info you know.

    Not all E models have the FCR carb. Someone else will chime in but at some point they quit selling the E with the FCR...

    Also the E rear caliper will not work on the SM swingarm. The rear calipers have specific mounts on the swingarm and the E mounts differently than the SM.

    Cool we will see what we can come up with. Original post will probably be edited many times.

    there are 50 state E models and 49 state E models. 04-07 california E models are 50 state. 00-06 the rest of the country got 49 state E models. california had 49 state E models 00-03. 07 was the last production year for the E in the US and they were all 50 state.


    49 state E models have E cams (maked A/B) ,not stage 2.
    49 state E models have the fcr carb and single layer base gasket (.010") and 10,500 rpm rev limit.

    50 state E,S and SM have the 36mm mikuni bsr carb,milder cams (marked D/E) and 3 layer base gasket (.030") and 10,000 rpm rev limit.

    there are more differences and changes thru the model years.
