My problem is that I had to drop the rear with a different shock, so I am trying to even her out. Maybe I should go about 20mm.

Looks like maybe you shouldn't go more than 10mm on the front.

Where i live it's like running the "Snake" for 20 miles just to get to town. All those curves are a workout, so I am looking for quicker handling/turn in. Along with that maybe comes a more unstable front end at speed, but that's where the damper comes in...right?

The damper will effectively quiet head shake. You can crank them down pretty stiff if needed.

You want quick steering, move to a 180 series tire. That works too.

I'm a die hard. Hey, I have this Fox Shock that I can't sell and I have this OEM shock. What's a guy to do?

I can always go back to the OEM, but why not see if the FOX clicks? I don't want to spend the money for an Ohlins.

I am going to bring the rear end up 3mm with a shim, and probably go 12mm on the front. That'll be 7mm more because I was already set at 5mm more. I already went to the 180 rear....Pilot Power.

Thanks for that link on lowering. Good stuff to know.

I feel that a heavier bike needs to have quicker steering for the road. On the track you usually don't have who knows what on the pavement. In most cases you have only your lane to deal with obstacles, which mean quick response and maybe even quicker come back. Where I ride, 10% of idiots come around blind curves in YOUR LANE!

Why won't it sell? You said that fox shock was for an old GSXR. There should be buyers for that shock for the correct application. Used fox shocks are still bought and sold all the time. If selling you have to get onto the forums for that bike. If you sell it you can find a cheaper non-ohlins shock for the RC51.

I see where you are coming from, just suggesting to try to sell it first. Keep in mind everything you are doing to make it fit is compromising the bike, not to mention the valving on the shock isn't even for the RC51 geometry, weight, etc.

I went on the GSX-R Forum and found it to be quiet the opposite of this one, so I decided to skip that. Besides everyone wants "specific application". Heck, I don't know, and there aren't many 1990's on the road anymore.

In test riding it, I haven't felt that big a difference from the OEM. Even with the Fox not "dialed in" right, how bad can that be to what the OEM offers?

I could see if I get a buyer and let them deal with figuring it all out, but it seems unless a shock is designed for a specific bike, it's all trial and error anyway.

Search the model or part number on google, or call fox and ask. Then you'll have the application.

I've never had a problem with the oem shock. It's a lot simpler too than your mismatched Fox issues. You can get your stock shock racetech upgraded too for a ltttle money.

I have heard nothing but a bad report about the OEM shock, so I am only going by what others have said here.

Seems like anything you do will cost you.

Thanks, I may just contact FOX (if I can).

Sounds like you're doing a lot of bandading to resolve an issue. It's simpler to go back to OEM or get a shock for your specific application. Instead you have the wrong shock, want to drop the front and raise the rear to get it to handle quicker, then turn up the steering damper to avoid head shake.

I have Ohlins 20mm in the front, Penskes shock. Dropped 10mm in the front and raise 5mm in the back. I don't have a steering damper and never had more than a headshake that didn't work itself out immediately. Steering dampers are not meant to correct a bike thats poorly setup. Its just an aid that should be set to the most minimal setting to get the last bit of performance out of the bike.

It seems he's trying to resolve a "perceived" issue with the rear shock as well.

What about your own riding experience? Is the rear all over the place? What is the rear shock not doing for you? What is the rear shock problem you find in your own riding? All the internet blah blah blah on the stock rear shock needs to be put into perspective.

The OEM rear shock does its job. Are there better options, yes. Do you track or race which is an extreme environment for a stock shock, and where improved performance is important? Where race tire grip and speeds make the shock work more. Got full leathers and get your knee down all the time? If so, get a better option.

On the street an upgraded rear shock isn't nearly as helpful as on the track. Nice, but not needed near as much as the track. And if you ride fast enough to need it, your riding too fast on the street and have other things to worry about.

There are way more RC51's out there with stock rear shocks than aftermarket shocks. You don't hear about RC51's crashing everywhere because of their stock rear shock. The bad reports you read about are overblown.

Again, if you don't want to spend much money, send the oem shock to get some valving and other upgrades.



And I believe it is better to have the OEM shock on the bike than to do what you are trying to with that mismatched Fox shock to make it work.

Yeah, I'd agree - the rear shock isn't that bad. A bit harsh in being too hard but that's a very rough way to describe what's not good about it.
You could always fit an upgraded rear link. That has the effect of raising the rear a bit whilst making the stock rear suspension less harsh, so for your GSR-X shock it'll make it feel a little softer through it's travel...
Sometimes used links come up for sale. ;)

My main reason for doing this swap is because I had the Fox Shock anyway and was just seeing if it would fit/work. But by the sound of it, you guys are thinking it isn't worth messing with it.

My suggestion is the put the bike back to stock. Set your rider sag ,to 20-25mm in the rear and 30-35mm in the front. Measure your fork lenght, static, top of triple to center of axle. Calculate your trail and adjust till you get close to stock trail. Adjust your compression and rebound and go ride it. If you want to raise the rear put in a link. Remember if you put a link in it, to reset you sags.
The stock suspension is quite adequate,when adjusted properly, when used with street tires.

I may just do that, as dealing with the Fox might get too much of a headache. Thanks for the great info, guys.

Don't forget to refresh/rebuild the components. Very important!
