yss shocks again

i've trawled a few pages so settling on yss shocks. i'm not fussed about cost but are the Z-series much better than the eco ones? rear end hopping and crashing over bumps spoils an otherwise great machine. ta.

Hi hondapete.

TBH I couldn't find a pair of Z series when I went shopping for rear Yss shocks, but decided to buy the ECO's anyway, to replace ageing Hagons.
The Yss eco's come pre-loaded but seemed a little soft for my liking, after comparing them with Hagons pre-load distance from top eye to start of the spring I found the Yss were 20mm shorter on stated distance. So I increased the pre-load distance to match the Hagons.
Much better but after a bit of trial and error settled for adding an extra 10mm making a total of 30mm increase on preload over supplied settings.
Perfect for my style of riding (fast hell rider lol)considering my mods to performance.
In combination with Hyper pro front springs, a pair of Michelin City Grip 2s, the Swing now feels planted under all conditions of road surfaces as a solo rider(johny no mates brave enough to go on the back)
Hope this helps you decide.
Be safe, be seen.

99 Suzi Burgman 400 with mods
09 Honda Swing 600 with a lot of mods.

splendid. i'll go for the eco ones and spend the rest on hyperpros. my last bike was a firestorm so i know where youre coming from!
