There recently has been some development work in both the UK and USA in mounting a R-1 shock on a Versys, using a custom made spring. One could use a standard Racetech spring with collars, but no point, when you can get a spring made for your weight and wound to fit the shock without collars at a better price. I will go for a progressive rate starting at 13.8 kg/mm to maybe 17-18 kg/mm over 100mm with a 150 mm range.
These guys are racing spring gurus - not the greatest website but good kit:

Constant rate is 110 USD custom made to fit the R-1 shock
I know that an 06-08 R-1 will work and that a 2010 will not. Not sure about any other years.
The 08 has both low and high speed compression damping
I just bought a used R-1 shock with 4500 miles on it for 35.00 USD on EBay and am now getting the spring made.
Will report back when the project is finished, but from what I understand it works very well, and the price is right at 150.00 USD for the finished unit plus freight. Machine work is required to bore out the mounting eyes from 10 to 12mm but machine shop work is cheap here. Not sure if one could simply push out the R-1 bushes and push in the Versys parts as the shock eyes are the same size (I think)
This combined with my fork re-valving project should have the Versys well sorted, and tuned for my bulk and style on our roads.
