(Like Jim said...)
You will be able to adjust your new shocks pre-load as it comes from the factory - that has been available on most shocks since the 50's.
What you may have to do it stop the bike and get out a pre-load ajuster wrench to do it and work around under the bike - OR as noted by TH - if you have a hydraulic (remote) pre-load adjuster you can do it while sitting on the bike or not by simply turning a knob - very easy.
I looked at Hyperpros site and cannot find a hydraulic preload adjuster on any of there products - they do have a simple and light adjuster ring that you insert a small rod - to spin the ring and adjust the preload.
so you are set - unless you want it fancy with remote and knob... your call but your shock will be able to be adjusted unless it came from a pre-war bike... ;-)
As your attorney, I advise you to buy a motorcycle. How else can we cover a thing like this righteously?
