• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

How can you tell when it is time to replace front shocks?

I have a 2017 F3-L with stock shocks. How can I tell when it is time to replace my stock front shock. Machine has 34K miles on it.
Thanks,
Jim
 
I'm starting to question the need for new shocks on mine. The ride has become a lot more rigid and it seems like I can feel all the bumps on the road. I'm trying to prolong the inevitable, maybe.
 
How does it roll in the corners? Do you have a lot of body roll, pogo effect on bumps, run in a straight line on bumps without chasing it? When you make a hard stop will it really crush the front end? To tell you the truth I am not the one to judge on this subject because I totally hate the OEM shocks they give us on our bikes, at least the F3's and RT's! I think they are generic junk, I have better shocks on my sled than my bike! I have 4000 miles on my new S2S and already plan on taking the fronts off before next Spring! I did it to my 2012 RTL and it was one of the best things I did to that bike! So if you have the coin and want to do a good thing for your bike, get it new shocks! If you don't have the coin, there are some spacers out there, I believe BajaRon sells them, they will at least give you a little more preload and get the bike off the ground a little more in the front, and that will give you a little better handling! Give him a call and ask him what he thinks, he's a straight shooter!!!
 
Good shocks are expensive. Manufacturers save a lot of money by putting relatively low quality shocks on new machines. This goes for most vehicles. Though I will say that BRP is providing better shocks than they did in the beginning. The first 5 years (2008-2013) were dreadful. Without riding on a good set of shocks, most people never realize what they are missing.

Determining when shocks need to be replaced can be difficult without a setup specifically designed to test them. In my experience, the typical lifespan for a set of OEM shocks on the Spyder is 35~40k. And this is quite generous. Lifespan can be shortened significantly depending on how hard they have been worked. If mostly on smooth surfaces, then 40k may be reasonable. If they have had a good diet of potholes or rough surface roads, like highways that have the rhythmic seam bounce found on some concrete surfaces, or other harsh and annoying roads, then shock life can be shortened to less than 35k.

Shocks are kind of like spark plugs in that they deteriorate slowly, masking the aging process.

Of course, if the shock is leaking fluid or has other obvious signs, they need to be replaced. But if they get that bad, they've probably been past their service life for quite some time.

A cursory test can be made by rocking the Spyder back and forth as violently as you can, then remaining rigid at the end of the last swing so that your body is not assisting in the dampening process (something that you will probably do instinctively). You want to pay close attention to how quickly the shocks control the action when you stop.

At the very most, they should only allow the bike to return just slightly past centerline, come back to centerline, and then stop. You should be able to feel the hydraulic action of the shock energetically suppressing the side to side movement. If at all possible, compare this to a new or relatively new Spyder for a better idea of shock function.

At about 50,000 miles, my 2020 F3S left front shock was leaking. Replaced it with a friend's take off shock with less than 15K on it. I also found out that those shocks are rebuild-able.
