    I have a 2013 Daytona (not R) as a dedicated track bike and I plan to upgrade the suspension. For the forks I will go with the RDS cartridges and for the shock with the DDS Pro.

    My first question is:
    • what should be the appropriate spring rates for the forks and the shock since I weight 114 kg (including gear)
    and my second question is:
    • if I install the linear suspension link kit from ukracesupport will I have to get a lighter spring for the shock?

    I can't comment on the RDS front, currently using the DDS front with 9.5 (I'm 100Kg) as advised by K-Tech, sure they will advise you on correct spring rate. Initially I thought this would be way to light but it works.

    Ran the DDS rear with the TRS linkage, You can keep the standard spring rate but you will have to reduce the overall length of the shock to keep the same ride height. I have for now reverted back to standard linkage, might play with the TRS again later on in the year.

    Put the linkage on at the end of last year, however didn't manage to spend enough time dialling it in. Tried the trusted internet for data... but everyone had used the standard linkage. I've got some suspension guidelines/settings from Graham Cox again with a standard linkage so thought I would revert back to standard and try the settings and see how I get on.
    The linkage is really well made and I'm sure it can be set up, just need a bit more time.

    Does it feel much different using? Do you know how much it changes the ride height? I'm Interested in getting one

    Don't worry guys, it's related to my question and I am also interested to know that as well.

    Also I 've sent an email to K-Tech with the same question about the appropriate spring rates for my weight and type of use but the only reply I got was just the address to a local dealer, nothing more nothing less.

    Not sure if they don't want to disclose such info over the email or if I have to purchase them first and then they can tell me....
     
  9. Speak with Colin at 100% suspension [email protected] he's the most helpful person regarding suspension and stocks all the bits you need. He also offers to setup services at track.

    just an update.. for someone like me (114kg with gear)
    DDS Pro came with 105 spring
    RDS with 10.0 spring

    The only thing that worries me, is that the place I got them installed didn't measure any sag to see if I am in the ballpark ... so I might have to do it myself...

    How heavy are you without gear? I am 92kgs without any gear on and i have just had a new dds rear, it came from ktech with 100 spring but I am going to try 105 as I think that is a little light
    I also run 9.5's in the front dds cartridges

    I'm 92-93kg (100Kg in gear). I have the same 105 on my DDS rear.

    so 14kg extra shouldn't qualify for a 110N ?

    This a grey area I think, I'm told a 100 is right but I'm on the cusb
    I know lighter lads running 105, not time to change before Spain now though so in dieting hard

    I just feel it's soft as my Nitron had a 110 spring in it and I loved how planted that was
    Also my springs are 9.5's which I think is stiff, in my limited knowledge I would assume hard front end would exaggerate the symptoms of a soft rear
