Getting comfortable riding a Harley solo is one thing, but riding 2-up in comfort is another matter. If your passenger is the love of your life the level of comfort you provide really should be better than you are happy to make do with when solo. So cheap shocks are out! Before I bought the Ohlins on my Glide I did a lot of reading here on HDF. Some owners had bought several different brands of shocks and spent a lot of time and money before discovering the delights of truly high quality Ohlins. I used their experience to take a short cut and haven't regretted getting them. We have never bottomed-out riding on them.

 

I guess I should have clarified a bit better in the OP, but I do 2 up riding maybe a handful of time per season. So it's just about always solo riding.

I won't mind firmer shocks, I just hate when I hit a big bump and bottom out when I'm riding solo.

Thanks for all of the input everyone! I think I'm going to try the Progressive 412HD.
