Than you're contradicting yourself here. If a spring is "pre-loaded", you've taken some of the stroke out so it has less compression travel = shorter.

Strider - I have been away from the Forum for a few weeks so have lost touch a bit with all the posts that have appeared since I last signed in.

I now have the rear shock (Evo AB1) from Mupo. I have ridden a couple of hundred miles with the complete MUPO set up. For me the bike has been transformed in terms of a well damped ride and staying well planted on the road. I am probably not the best person to describe the changes but the way I look at it is if it tracks the road surface well and is comfortable then this in turn builds my confidence on the bike.

Posting the pictures may take a bit of time as I have trouble getting a web link to the files to work.

Two views of the Mupo rear shock if I have loaded the links correctly.

People talk about them being sprung light, I'm 144 pounds and am trying to figure out the proper spring rate for myself. I have used racetech for some of my other bikes but I do not see the Hyperstrada listed on their site.

FYI I have the LOW version.....

Thanks for your help.....

I Ride: anything I can get my hands on
Racetech told me that the stock spring rate on my "Normal seat" 2013 was only .62 Kg/mm. I weigh less than 155 in my birthday suit and I think the .85 springs they specified are just perfect.

OTOH I put .95s on our SV650 and they seem not too stiff, considering possible track use. It has R/T emulators and I set the forks up more or less per their instructions - 15W @ 130mm and 10mm preload.

Please check my thread on the R/T fork work for more info - "Fork Upgrade for Hyperstrada." There are other threads that address the low model, too.

Did you get your forks done as well? Thanks for sharing the images of the shock, it looks great!
