    Hyperpro spring kit - anyone fitted it?

    Hello folks, I've just ordered the Hyperpro progressive spring kit for my TTSE. Was wondering if anyone had fitted these springs to their bike, and if there were any hints/tips/issues you could share? In principle it's a simple exercise, but do the electronic shock absorbers complicate things at all when dissembling / assembling the forks or shock assembly? Any advice gratefully received, TIA!

    From my experience in this regard, I can say that on some occasions what I have done is insert stainless steel washers inside the shock absorber bottles with the same diameter as the springs and thus I have managed to give the springs a little more hardness to the front shock absorbers.

    The truth is that with the washers there is great difference and comfort when riding the motorcycle.

    Adding washers will change the preload but not the spring rate, BTW.  It will still take the exact same amount of force to cause the same amount of deflection.  Adding washers do not make the forks "stiffer" but willl raise the front end slightly.

    As far as preload is concerned, Racetech says the forks should be compressed about 1/3 of their maximum with a Rider sitting on the bike with feet off the ground ( obviously you need a Helper to measure this ).   And Racetech prefers straight wound springs over progressive rate springs for easier setup / tuning.

    I found a good article about Suspension Setup by a guy named Dave Sallberg,  a local Michigan Rider.  He covers about everything in a fairly clear manner.

    Here is the link : http://msta-se.com/MC/susp.htm 

    He has a section on Spring Rate and Spring Preload.

    I had seen videos of Keith Code talking about this, which many bikers are unaware of.
