Was previously looking at either the Progressive 412 Series or Fournales for my 2007 FXDB, but have seen a lot more YSS lately and not that they have an outlet in Adelaide www.yss-australia.com/.
Has anybody tried YSS on their Harley's?
I fitted YSS RZ362s to my 09 FXD about a 1000ks ago and have had no problems to date, YSS match the spring rate to your weight and riding style and also will custom build the length you want when you order, something Progressive dont do (i think). I can report a massive improvment over stock, but anything would be i guess. I havent tried Progressive but have heard some people complain of harshness.
Wow!!! HO your worried about suspension, after all that Asian cavorting you'll need to put ya training wheels back on mate
