I do the occasional track day, but want comfort as well as improved stability. My favourite thing to do on this bike is a spirited 2 or 300 mile day through the mountains.
What should I do to her?
I'm still loving the performance of the revalved DU333 Ohlins rear unit on my S4Rs. See the link at my sig line for details and charts. The ride is very comfortable if you have it adjusted right. But you can dial in extra compression if necessary.
One thing I wanted to mention was how much I have appreciated the ability to adjust both the compression damping and spring preload while riding. I've thought about this quite a bit on the past couple of rides.
It's not only how easy it is to experiment, it is also that you feel the change immediately, and without the break in rhythm involved with parking the bike to adjust.
The hydraulic preload adjuster might seem like overkill for solo riding but I continue to find pleasure in using it to fine-tune the steering response for the conditions.
Put in some miles on one of the Skyhook Multistradas recently and couldn't help thinking that for all its electronic trickery, my bike rode better and the key suspension adjustments could be made much more easily.
FWIW, I find that the rebound on the Ohlins unit doesn't need any adjusting over the course of a trip, now that I have it where I want it. The compression however can be wound up for sportier use or high speeds, and then wound back if I'm feeling more mellow.
I think on the compression side there is some loss of crispness compared with a piggyback unit due to flex in the hose, but the upside outweighs that.
