Sweet willl give a measure up tommorow night and also talk to dad

some stuff that might or might not be useful:

a shock length/spring stiffness list from the sv650.org forums:

YEAR MOTORCYCLE LENGTH SPRING
===== ========= ===== =====
00-03 GSXR750 325mm 400#

01-03 GSXR600 325.5mm 325#

01-02 GSXR1000 329.5mm 430#

03-04 SV650 330mm 430# <<<==== stock 2nd gen...05 should be the same

99-03 GSXR1300(Busa) 330mm 700#

04 GSXR750 332.5mm 408#

04 GSXR600 332.5mm 425#

03-04 GSXR1000 332.5mm 480#

99-02 SV650 337mm 510# <<<====stock 1st gen

04 ZX10R 338mm 540#

03-04 ZX6R(636) 340mm 540# *corrected by e lo...thanks!

96-99 GSXR750 345mm 375#

97-00 GSXR600 375mm 375#

05 GSX-R 1000 332.5mm 450# <<<===added by me...spring rate from racetech.com, length from ohlins.com

I think the stiffness figures are in lbs/inch.

the racetech website also lists the stock spring rates for some bike's shocks, it might be of use.

What did you measure the eye and shackle widths with? I think 30mm is a common width (how common I don't know).

Theres also another list on the banditalley forum:

doesn't have spring rates though.

Good post erik. Wonder just how different the Hyosung is to the SV. There must be alot of people out there trying to fit other bikes shocks to the SV's. I think your right about the widths of the eyes but there are other factors to take into account. I had a late model GSXR shock and it didn't clear the swingarm on my SV. Another thing to watch is the clevise end as theres little room between the dogbones and if the clevise isn't threaded you can only fit a cut down nut.

I have a shock from an injected SV650 here and its dimensions are:

Length eye to eye 330mm
Top eye 30mm wide by 10mm hole
Bottom clevise 30mmm internal wide 40mm external wide 40mm deep 10mm metric fine.
Spring is around 75mm outside diameter and is made from 11mm stock.

Forgot to ask why DB wants to change his shock out as the type he seems to be after is off an around 20 year old bike?

I have a k4/5 gsxr 600 shock let me know if you want it.

**svr** · 17th July 2008, 13:00

Useful data (would have saved me from wasting my time fitting an old gsxr-600 shock many years ago as per sv.org `hot tip'...)
You also need to know the stroke length tho.

**CookMySock** · 17th July 2008, 15:08

texmo, does it look like it might be in the ballpark ? How much do you want for it ?

GSVR, Hyosung shock is not adjustable, rebuildable, the spring rate is wayyyy too high, and in general it is a much better boat anchor than a rear shock.

I fully expect to have to change the spring. Also I have two GT250R bikes on the property as well, so it if it is too soft for the GT650R then maybe it will be better on the 250.

So basically I want to start the process or exploring this so I can have it sorted for the summer. There is not much data for they hyo suspension around. I have discovered there are Racetech bits for the forks that Robert can fit and set up, so I am looking forward to that.
