    Possible, but why blue. Progressive springs are not a good fit on that fork anyhow.

    I didn't see in his posting that he mentioned blue springs. That's why I brought up progressive springs.

    He did not say they were blue so you may be correct. I should qualify the progressive spring statement. If you are running the forks without any valving mods then I guess you could realize some improvement in bottoming resistance by installing a quality variable rate spring set. This is what they call riding the spring. In other words less control with damping but more bottoming resistance with spring only. For that bike I would for say a 180lb rider if they were going variable maybe .60kg/.72kg might be a good starting point for the aggressive guy. If the spring does not have specific rates stay away. One size certainly does not fit all and many variable fork spring sets I see are low quality.
    You will get a better ride, better performance all around with straight rate and real valving both mid and base but some do not need it.

    Just FYI:

    Torque is being humble here in his anonymity.

    He's the finest suspension builder I've met and has done a lot of work on all my bikes as well as my entire riding posse.
    Good dude. I don't ask questions, I just take him my stuff and he makes it work.

    So, i did change tthe springs and the old ones where 60mm shorter. Now i have progressive springs in front and rear shocks. Deal is solved! The ride now is great! I was going 100km/h on the forest road and did't felt any hits on the bars. Thanks for the help guys!

    Could the new springs that are 60mm longer than the existing ones cause some coil bind?

    Guys, hello to you from Russia. Please tell me. Now I have 990, 09 years old. fork stroke 210mm. I want to make 265. What spare parts do I need to buy? Studying, I understood like this.
    1) 48600 240 Inner tube D = 48 L = 595 2003
    2) 48600241S HYDR.STOP L = 200mm D = 31.9 CPL
    3) 48600225 Adjustment tube 6x482
    4) 48600253 PISTONROD 14x11x1 L = 516
    Did I write everything right? or something to add? Or maybe I wrote too much?

    All I had to do to make my 2009 Adv with 210 travel into 265 travel was use the the damper rod and rebound adjuster rod from a 2003 S.
    Only 2 parts required for my conversion.
    All other parts were identical.

    EDIT: And spring spacers
