For information I contacted Hyperpro with the information below and got a good response:
I have been recommended your spring on the UK V-strom forum.
I have a Suzuki DL1000, 2018, 1500miles on the clock, we ride mostly two up, combined weight around 176kg split 103 rider 73 pillion, we have 3 set Suzuki panniers.
I have the preload currently on maximum and I cannot achieve the desired SAG, so there is no chance of achieving this when fully loaded.
Will your spring achieve this? If so please let me know the code and I'll order. If not do you do a custom spring?
RESPONSE
Hello Ian,
Our spring is indeed stronger. So it will be an improvement over stock without a doubt.
Idealy I would have advised you a spring that would be a tad stronger, but I do not have this available. This is because the DL1000 uses a very specific spring on the rear shock.
Alternativly, you could add a 3mm spacer to our spring, so the range of the original hydraulic preload suits your weight.. But this is something you have to macine yourself then.
As said: our spring will be a big improvement, and with a little tweak (the spacer) will match perfectly.
With kind regards,
Met vriendelijke groeten,
