The stock rear shock was killing me. I'm only about 160 pounds with gear on and I was getting bucked around brutally to the point where the bike was difficult to ride and I couldn't really get the front end to behave.

I put on the Razor R, set up the preload to 32mm front and rear, adjusted the rebound and compression front and rear and holy sheet.... The bike is glued to the pavement.

I did some quick test runs this afternoon and did some high speed sweepers between 80 and 100 mph and it was effortless in comparison to the old shock. I still may get the suspension tuned professionally but it is light years better than it was.

One other thing I noticed is that the snatchiness of the throttle seems to be better with the suspension working. I have previously done the TPS adjustment which helped a lot but now rolling on and off is just smoother especially trail braking/apex....

The installation was a pain in the ass. I did it with the wheel on per the video but I ended up having to completely disconnect the swingarm linkage and use a jack multiple times and places to get the shock in and out. Took about 2.5 hours but worth it.

I don't have passenger pegs so I improvised and just used two big oversized nuts as spacers and the install is clean.

If you're on the fence, get you one.

Mate I'm with you on this one and yes it's hard to believe how much better the bike handles.
I had the front done at the same time.

A good rear shock transforms the bike, enjoy.

I installed a Razor R on my 2016 a few months ago and my only regret is that I didn’t do it sooner. Much more comfortable for the longer rides that I tend to take.

It was a bit of a pain but I did not have to disconnect the swing arm. I used an ABBA stand and a floor jack. Worst part was having to ask the wife for help (to push the connecting bolts through). But that’s my cross to bear.

I used an automotive scissor jack between the rear tire and tail tidy, stacked a couple of flash card decks and a book in between as I had no wood, and bungeed the rear brake while having it on a rear stand. For safety, I should have strapped the tail hanging from a ladder but luckily it was pretty solid and I didn't lose an arm.

An ABBA stand would be nice and I'm tempted to sell my bulky motorcycle lift for a Skylift. It just seems a little sketchy to have so much weight on a couple of small pins and would it damage the swingarm pivot? I'm guessing a steel rod through the pivot and placing it on jack stands would bend the rod.

You're overthinking it. Every time a rider does a wheelie he's standing the full weight of the bike (along with the added component of hard acceleration) on the rear wheel and swingarm but it doesn't bend the axle or the swingarm pivot tube.

Hey MotoRiderGA, it sounds like you've discovered what many of us have - that rear shock is a complete piece of schizen. Once it's replaced with a quality K-Tech, Wilbers, or Nitron, riding the bike becomes so much more enjoyable. A bike that holds the road and handles properly is a faster, safer bike, but more than that, you just want to ride it more often. Worth the money. Thanks for sharing your post. I keep preaching but sometimes I think only the choir is hearing me. Maybe your post will get a few more congregants to upgrade that rear shock and 'see the light'. (And if I could afford to redo the front end, I would, but once you get the back end sorted, the front seems livable, 'as is'.)

I've been wanting a new shock but looks like a PITA to install. How many hours should it take a shop to install? I have a nice motorcycle jack I use for my cruiser but the GSXS has no frame tubes under the motor like a big V-twin bike does.

So they make Factory banana swingarm's for those who don't want the bother of doing wheelies to get the bend ?
