Rear Shock

I was doing my daily Ebay watch. And I came across a bunch of rear shocks from RC51s, 929s, 954s, but I have really been impressed with Suzuki's suspensions and setups. Front forks especially. I was wondering if the rear shock from an '05 GSXR1000 would be worth trying to mount on the 4th gen rear? Because my rear is saggin' bad and i want it to perk up again and maybe a little higher. So then i guess my second question would be what is the stock length of the 94 VFR shock, and the stock length of the GSXR setup?

do a search on 929 shocks... there's quite a few people that are picking those up as replacements w/ some minor fabbing required... seems to be the best cheap solution for a shock swap.

I know about a couple of those, but like I said, I like the Suzuki suspension and it seems better to me. There will probably be about the same amount of fab going into it. My biggest thing is find the shock length of both so I can compare. But if it comes down to it then i will probably end up doing the 929 rear.

check the spring rates on the Suzi's.. I bet they are way off from the VFR's...

fox twin clicker...
i contacted the seller to see if he will sell it for 250........... will let you know.

the $40 I spent on a 929 shock was the best $40 I have spent on my bike.

Other than getting the forks done...... that was alot more. But anyway.
You can't go wrong with that upgrade.

Probable clearance issues with the GSXR shock. The resevoir is built in to the top of the shock. I'll look in my set up books on the dimensions when I go to the shop. (I raced them last year)

Here's a picture of either a 2004-2006 GSXR750 shock or a 2004-2006 GSXR1000 shock. They all look identical.

As you can see, the reservor is on the wrong side when compared to CBR929 shocks.

Also, notice the bottom mount of the GSXR shock is not an eye-type mount.

OK, when it comes to shocks and what will fit, here's what I do.

Go to Ohlins shock list

I like this list because it tells me:

1. What the stock shock length was.
2. Which Ohlins shock fits
3. What the size and options were: i.e. 46 HRCS 46mm, HRCS remote adjustment and gas cylinder.

Now I can also look for any other shock that is:

The same length
Similar options and size

Because I already know I will get it rebuilt (if used) to MY specs, and I will get a new spring to my specs from probably Hyperpro.

94-97 took a 46HRCS at 324mm. Same size as VFR800, same connections, I don't know, but I can look for sale models and see.

As a last resort, it is an option. For my 93 I used the shock from a 93 ZXR900 (KA403 Ohlins) HRCS and got it revalved and a new spring for about $600 total. Sure, I could have gotten a Penske model for that, but with little $ over time, I ended up with the EQUIVALENT to the HO002 Ohlins, virtually unavailable, if at over $1200, usually. I know, one came up this month, but thats the 2nd one I have seen in 3 years.

Hmmm could have sworn I read on a thread here that there was an Ohlins for a 4th gen just last week.

So basically the best route is just the 929? I think ill end up just sucking it up and do the 929 mod.

the 'best bang for the buck' route, yea... getting some high tech shock like a Penske or Ohlin would be the preferred way if money isn't an issue.

I just put a 929 shock on my bike as one of my winter projects, 40mm aluminum spacer and new bolt, done, was easy and inexpensive

I know it's a lot less expensive to go the 929 route, but the things that kept me away from it were:
-Spring rate may not be right for you & your bike
-Valving may not be right for you & your bike
-The shock may be worn out already. (This is kind of subjective...The stereotypical liter bike (or almost liter bike like a 929) lives it's short life doing stunts. Stoppies are hell on the shock's seals when the bike comes crashing down on the rear wheel. The clunking noise just never sounded "good" to me. If you can be sure the PO replaced the rear shock while it was near new in favor of an aftermarket one for racing, that's a different story. But, if the eBay pictures show rubber all over the shock, you can assume the life the donor bike has led.)
-If you are going to get the new-to-you 929 shock rebuilt, you may as well have it re-valved and re-sprung for your weight and riding style. By then, you're more than half the cost of a custom aftermarket one that is made for the bike and will likely perform better.

That being said, the difference in cost may be worth it. It all depends on your situation. For the brief ride I took with my new shock, I love it. If I could just find a good place for the remote reservoir, I would be even happier.

Working on it, working on it....
but 1st I'll be off to Luxemburg and Barcelona (week's holiday coming up)

It's possible that my thread on this got wiped out.

The short version is, I needed the same thing form my 1993. I researched and went with Hyperpro.

I got a custom made and valved GP shock for $750. An engineer and sales guy conference called me from the Netherlands, and made just what I wanted.

It transformed my bike. I think I got the ride of an Ohlins for the price of a rebuild. I recommend it highly (and have no affinity other than having one on my bike).
