00 gsxr 750 shock swap

[vpower102]

im interested in doing this rear shock swap on my 92 600 but not finding to much info other than whats stated in the shock swap wiki. does any one have any info on this swap? is it worth it? complications?pros/cons? any input would be really appreciated. thanks

ps found a good one on ebay for 40 bucks shipped

I did the B12 upgrade on my prekat 600, and it was well worth it.

Are there any good swaps for a post 600?

-2000 GSXR is not on the swap list
-Contact Tmod about other possible options including a rebuild

--'00 GSXR 750. (SlytlyDeranged) Notes: Battery box needs adjustment. Raises rear height. Adds adjustability.

Well, there you go.

GSXR weighs a lot less than the katana...

[vpower102]

so does the r6 but people still use that shock, would the r6 shock be better?or what

[steves]

The folks using the r6 shock are having them re-sprung to match the weight.

While the weight of the bike does come into play the leverage is what really makes a difference in spring rates, Take a CBR600, They have a stiff spring yet the bike is lite. The R6 spring is rated a bit stiffer than a pre 600/750 spring so if the stock spring is fine for you then the R6 will not require a re-spring. It will lower the bike but you have to decide if you are willing to lower it a bit. The GSXR shock is sprung lighter than either the pre 600/750 shock or the R6 shock, The R6 has digressive valving where the GSXR shock does not. IMO a shock that is setup for one bike will not transfer over to another bike and be valved correctly for the weight of the rider, leverage and style of riding.

What is the benefit of digressive valving on a bike? Maybe I don't understand what that means well enough......

Ah, didn't remember seeing any notice of that.

Respringing should be at the top of anyone's mod list for sure.

Hi I'm running a 08 R6 shock with factory spring on the rear of my Pre 750 (bushings courtesy of Tmod) and I'm really happy. lost about 3/4 inch height
without me on it. I'm no light weight about 225lbs but its defiantly a huge improvement on the worn out stock shock. Not perfect but a step in the right direction.

Quoth the internet:

Digressive valving is a revolutionary way of valving shocks that is entirely different than in usual shock absorber design. Traditionally shocks have more damping force at higher shaft velocities, and that’s why they are called progressive shock absorbers. These shock absorber design have multi-stage valving to cater to various types of road conditions. Despite of these multi-stage valving, they are quite different from digressive valving, which is opposite of how shocks have been traditionally valved.
A digressive shock absorber has stiff, progressive damping at low shaft speeds (less than 3 inches per second). This helps to control car body motion like roll, dive and squat. At this point, it functions like a typical stiff racing shock absorber.
At higher shaft speeds, between 3 to 10 inch per second the damping force is more or less constant despite the rapid change in shaft velocity! The result is the suspension is kept supple in response to bumps and irregularities in the road, therefore traction is maintained on bumpy roads by reducing suspension hop, yet provides a firm ride, even at the high damping rates needed for body motion control. First used with success in off-road racing, digressive shock absorbers have only recently made their way into the on-road racing area
