Thanks Studley. I saw that thread and it looks like people saw the same YSS data regarding shock lengths. I was curious if anybody had actually measured one to get the actual length.
I've emailed several shock providers (YSS, Hagon, Yacugar) and have only had a response from Hagon. The more I read, the less I want a Hagon as I am 175 pounds and never have a passenger. It seems like Hagon uses one spring for all riders. If priced competitively, I'd like to try a Yacugar. I'm very happy with the Hyperpro on my BMW and my understanding of Yacugar is that it is made up of former Hyperpro employees and they get their parts from the same sources. So you get a shock similar in quality to a Hyperpro for a bit cheaper. Not sure how true that story is, but they seem to get good reviews.
The Hagon will be $399 and I know a Hyperpro will cost me $650. I'd much prefer to stay closer to $400 than $650. I believe the shock on the bike now is original with 37K miles, although it may have been resprung - it seems very stiff.
