Back off Vee pre-load after ride ?

Since new, I've been backing off the shock preload on my 07 after each ride thinking it would provide long term longevity benefits for both the spring and adjustment " system "

Probably an old school habit I've used for many years on various vehicles ( race cars etc. ) but not sure if there is any real benefit to this for the Vee.

My size requires 3/4 + preload for best all around feel but not sure backing it off after each ride is necessary. I will say the shock / spring still seem to be holding up just fine at 40,000 miles so maybe it has helped ??

Any thoughts appreciated.

The preload doesn't have anything to do with your spring compressing more, it just raises the ride height. If you like yours at 3/4 just leave it there, it will be fine.

It sounds like you've never set the sag. I'm not familiar with "race" cars, but setting the sag on motorcycles is one of the first things I do. There are numerous threads about how to do this. Of course you can also find the procedure on youtube.

Basically, I'm adjusting the " sag " and ride height each time I ride by the amount I compress or " pre-load " the spring.

You want about 40mm of suspension sag from full extension when the bike is carrying its designated load, including the rider. Unless that changes between rides, as in adding or subtracting luggage or a passenger, there is no reason to change the setting. You might want to "wiggle" the rear knob occasionally to keep the mechanism free but that's all it needs.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.

Once the weight of the bike is on the suspension turning the preload knob has no affect on the spring compression. You're just raising or lowering the bike. Set your sag to 40mm and then leave it be.

Putting the bike up on the center stand takes the load off the rear spring (and slightly increases the load on the front), but that's not what wears out. The mediocre damping of the rear gets more mediocre.

The below paragraph is from the Progressive suspension website. The amount the spring is compressed by the amount of preload is what determines loaded ride height plus many other factors.

My original question was based on leaving the spring in a more compressed state ( via high preload setting per below paragraph ) I was just wondering if I would get longer, useful spring life by leaving it in an uncompressed state when not in use by backing off the preload ?

Look at two identical shocks, one with full preload, and one with no preload. The shock length is the same, its the overall length of the spring ( because one has been compressed ) that will be different.

Below is from Progressive site:

"This is where Preload Adjustment comes into play. By compressing or uncompressing the spring a small amount, a shock can be perfectly tuned to suit the conditions for which it will be used."

I'm thinking an analogy might be similar to why it is important to back off the preload to zero on a torque wrench when not in use.

That information about spring compression is only accurate if the wheel is off the ground or the suspension is topped out. If the wheel is on the ground and the spring is not topped out, changing the preload only changes the height of the bike. Don't worry about the spring. It's not going to take a set. Just set the preload so the bike loaded with the weight you will be carrying compresses the suspension about 40mm from full extension.

Just your getting off the bike is like lowering the setting on the torque wrench.
