IMO this was money very well spent. I hated the stock Showa forks since day 1, very little damping, felt like a pogo stick, I put in progressive spring kit, didn't like it, swapped it out for works, changed the orientation of collars a couple of times to shorten spring duration on the works kit(to stiffen it up I'm a big guy 6'3' 235), and got something I could live with, now after adding the Intiminators I am completely happy with the front. The rear has been a similiar trial and error, progressive 440's, works, and now YSS Z 366TRL. I was going to spring for a pr of Ohlins but decided enough already. My bike already handles great compared to stock(also have sputhe positrac and an SE fork bace) I'm a big proponent of suspension first, then brakes, then motor work. Anyone want a pr of 440's HD 12" (chrome springs)and a set of progressive fork springs cheap(already sold the works rear shocks) they only have a couple k on them and look perfect, 270.00 plus shipping? cost new about 570.00 for the set(rear and front).

I was planning to go with 440's on the back, and this thought was reinforced when I learned they had the IAS technology from Ricor. Can you share your experiences with the 440's, and perhaps describe what you like about the YSS shocks? The 440's are generally well liked, but I have seen some unhappy users who got the HD versions. Could that be the issue you had?

I'm not that experienced in dialing in much more than preload. Do the YSS shocks take a lot of adjusting to get right?

Thanks!

I find it interesting that everyone talks about the 412 or the 440 but never the 418? The 418, too me, is a good shock and has rebound damping adjustment, something I feel is the biggest problem with the rear shocks.
I would get the front working better and see how the rear reacts and work from there.
It is best to to do suspension mods in stages so you can compare to your starting point and this includes the front. It is nice to know which mod did what and if you do 2 or 3 then your sitting there scratching your *** wondering which did what and if it is not working which to change! I would recommend starting with the intiminators since they really change the fluid dynamics, then go to the front springs if you feel the need. The only reason I suggest this is that if you start with the spring, especially the works, you're probably going to have to go back and reset the crossover point and or preload.

Race Tech makes great products, Ricor just uses a different technology with our IAS Valve (aka Intiminator). Looking forward to the feedback and comparison reports.

Better shocks will have an adjustment for rebound(how fast the shock goes up) and even better compression too(how fast it goes down)Hope this helps.
