    Default M109R Clutch Spec Thread - all you need to know

    As some of you know, there was a clutch change that I believe occurred after the 2009 model year. Suzuki went from a 5 disk setup to a 6 disk setup with longer springs. After a bit of research, I have discovered that all models from 06-20 use the same clutch plate. The difference in thickness is actually found on the smooth metal plates and not the friction parts. Here are pictures. One other thing I found is that the new clutch plates do not have staggered pads like the original plates from my 2012. PSS. Sorry about the sideways pictures.

    Here are the parts

    Driven plate - bare metal. These are the ones that should be thicker on the pre 2010 models.

    If you want to upgrade to a 6 disk clutch, you need 1 additional clutch plate, the longer springs, and the new thinner driven gears which is pictured above. PS. I did not replace the bare metal driven gears so they are not in my parts list.

    Well, I think it is great when others really get into the differences between Gen1 and Gen2 versions. That is what makes this site 2nd to none when it comes to information about this bike.

    Your info is not in line with the OEM part structure.

    Gen1 2006-2009 (US models)
    #5-1 2006-09 PLATE #1 21441-48G00 Fiber Plates (5)
    #9-1 2006-09 PLATE DRIVEN #1 21451-48G00 All Steel Plates (4)
    #10 PLATE DRIVEN #2 21451-48G10 Fiber/Steel Plates (2)

    Notice the service limits between the Gen's.

    So the only plates that remain the same is the #10 plates. The difference between the Gen1 and Gen2 plates is the thickness of the Fiber and steel plates--- Gen2 being thinner to make up for the same stack height in the unchanged same clutch basket. Both plates have to be thinner as there is an extra plate of each in the stack.

    All this info is available online through ordering sites and service manuals/addendum's.

    You have intrigued me. Give me a day, I could post some pics of early model plates as you did for later models. This will be good info for future issues.
