765 Street Triple Rs - Rear Suspension Preload Not Adjustable?

Set up sag just like any other bike, let the lawyers that wrote that in the manual kiss the pavement hard.

 

Adjust as you see fit if you know what you are doing, it's a free world!

Just be aware that you really only have an effective adjustment on the pre-load of +/- 5 to 6mm, if you are going much beyond this you really need a change of spring weight, but generally if you can get sag right within 5-6mm of turns just dial in sport settings on the adjusters & the bike will be right for fast road or track use.

I did do a set up guide somewhere on this forum from when I had a 765RS, I will see if I can find it & post a link.

 

Link below, I have used this with success over the years, I have learned a bit more about set up since I have been racing but this guide still a good place to begin
It's just the spring & valve rates become far more important for pushing as hard as you do on track, I have destroyed tyres very quickly when the settings were a way off.

I didn't go for harder springs, but I used more than the 5-6mm of spring compression adjustment, at that time I wasn't aware that this was all you should use.
It was Race Labs Suspension guy when setting up my RSV race bike that told me that you should only use 5-6mm more or less preload on the threaded adjuster, on the 765RS I had my sag set in the middle of the 'road' range 35mm front & 43mm rear & found it handled very well for the road.
I didn't take the 765RS on track but I am sure it would have been a little soft for track use on those settings.
