    There will be no official suspension service. What are you needing to have done? I can do your sag set-up & have the tools to change shock & fork springs etc, but since I am not bringing my trailer I didn't have any intentions of hauling all my gear like that as some of it takes up a lot of space.

    I have a new spring ordered, but it didnt show up today and chances are slim that it will show up tomorrow. I guess ill just get someone to help me ball park the sag and try to get it dialed in when i get the new spring on.



    What about pictures?

    Dunno about the photog service, somebody smarter than me will have to answer that one.

    Nope certainly don't have one of those, but you have piqued my interest to say the least. What is that going on??? I have never even seen a 365lb spring infact I have never even used one that was less than a 90 (514lbs) & that was for super lightweight rider....

    That spring has a rate of 6.52 right? Well according to the chart on the Section8superbike site a 748 comes factory with a 6.4. My bike is currently fitted with a 1091-19/70 which is for about a 180lb rider right? Well all the charts ive seen say that thats about the right rate for me on my bike. I only weight about 120lb and i ride a 2000 748 with Ohlins.

    Yup 6.52 kg/mm



    I wasn't trying to refute it, just curious where it's going. I've got very little experience with Ducati's although I have been doing a few more lately (they typically come very undersprung from the factory), but I have zero experience with 120lb riders :lol:



    I bet that thing is a rocket ship with you onboard.

    Shoot!!! Acording to that chart, that "small" 90 is for a 235lb rider.



    I guess different bikes have different forces/angles working on the shock so you need different rates.

    Yup, I mostly do Japanese liter bikes & the current trend is for longer swingarms & many of the rising rate linkages they are using now are getting less progressive & more linear so they need stiffer spring rates to give the same sag numbers & keep the swingarm down angle correct.
