Question Fork preload adjuster query

This query is for 2016+ 500 owners or older versions who have installed aftermarket preload adjusters.

How is your experience adding more preload to the forks?
Does it really add any benefit in the riding situations?

I have 2015 500R and wondering shall I add adjuster or not?

I have same bike and year. Yup, its worth doing. Got off ebay, about $35. A few threads on here about how to instal. Start off with the settings right out, and slowly firm them up until you find the sweet spot. For the money, its a good mod.

Thanks @ hillscbr. I have ordered 2016 OEM preload cap for this. Could have gone ebay but decided to do OEM. I am not sure how much of adjustment in terms of mm is provided by oem cap. The aftermarket does about 20mm. Any thoughts on this from 2016+ owners?

I've got a 2016 F model and have not bothered to experiment at all as of yet with those front pre loaders. They are still at the stock setting.

On other bikes I've owned, have always adjusted the pre load to limit brake dive. I always leave a little dive in, that will get you in the ball park.

The fork pre load adjusting screw does make a difference but it is only minimal. I changed the oil to a more denser performance oil and that made a far more change to the feel to the front of my bike. It also made my ABS more responsive.

@wings: What oil you are using now?

Here is my take on pre-load adjusters. They are most useful if you are going to try and accurately set your rider sag. That is one of main measurements to get a suspension set up to your body weight. These bikes come set up with a good average range set up for a normal sized rider. If you happen to weigh a decent amount over 200lbs your suspension will settle allot lower and thus need to dial in more pre-load to keep the suspension from bottoming out sooner. If you are a very thin and light person it may be too stiff. If you are going to be riding with a passenger you also want to set both the front and back higher to handle the extra weight. If you aren't familiar with how to set the sag, do a search on here, there are a few tutorials on it. It is basically a measured difference between how far the suspension settles with you off the bike, and then measure the difference when you sit on it. Having adjusters allows you to set it in the proper range for your personal weight. (preferable with your full gear on) Hope this helps.
