the HM has longer suspension ways, so, the shock should be longer also.
i suppose it would not be good for drivability to use it without HM fork also.

For the cost of the HM shock I bet your could get the proper spring for your weight and still have hydrolic preload adjustment .

Unless you are talking about the SP's Ohlins, there is no difference in rear travel between the '13 - '14 Strada and the Hypermotard. They both offer 150mm of travel. The 'low seat' and 2015 Strada have 130.

Once you fix the weak front springs, the rear sag matches the front a lot better. I'm no heavyweight, and the stock rear seems just about right.

According to Ducati they list the standard Hypermotard as having a seat height from 870mm-850mm (890mm on the SP), which I'll assume is due to the adjustable spring perch rear shock. Keeping in mind that those measurements are with the factory seat which is about 10mm taller than a Strada. Below is an example of a standard 821 shock:



The standard height Hyperstrada has a fixed seat height of 850mm (830mm on the low variant), on a fixed spring perch rear shock pictured below:



So theoretically, with both bikes essentially sharing the same frame, swing arm and forks, just by swapping the rear shock you should be able to get a standard Strada to have an adjustable seat height of 860-840mm.. Which would be the same thing as a Motard putting a factory Strada seat on it.

Best of all, the geometry of the bike wouldn't change beyond factory specs.

Those shocks really don't have a ride height adjust. Preload is like ride height but neither of those shocks is length adjustble. I'd venture to say they would be virtually the same in preload based ride height. If you want to lower the bike you'll need a shorter shock or different linkage. A linkage being the cheapest method as I understand things.

So, cabin fever is setting in?

Close but no cigar, Strider. Preload adjusts nothing but ride height. It should be done after getting the spring rate right.

Zibbit, there is no difference between adjusting preload with the hydraulic piston or the threaded rings other than convenience.

And these bikes have no linkage!

yes and no

technically you are right, but with adjusting preload also the spring gets more compressed. so, when its already compressed, a compression of a given amount gets harder than not preloaded.
so yes, you change height with preload, but also hardness

This is what I ment to say but I did it in a long convoluted way. The "proper" way to adjust ride height is to change the length of the shock as a whole. Changing preload changes what part of the total shocks travel you are using. Which is much like ride height, but your maxium and minimum heights are still the same. To much preload and you will bottom the spring out, but your seat will ride lower. Not enough and you will top the spring out with your seat being higher.

And I have SERIOUS cabin fever, especially with 60 degree days in Minnesota. Alas I none of my street legal bikes are road worth at current . So I have to live through youtube.

i think its reverse

too much preload makes bike (seatheight) higher
not enough preload makes bike (seatheight) lower
