rear shock change

Wow, I can't flat foot the bike with the normal shock on, let alone that bad boy.

ZX6R is actually couple of mm lower, 335 vs 337, something like that. Not sure about -10R

Really? Looks a lot longer in that pic?

10r is a bit longer than the curvy one a fair bit longer than the pointy one (still not long enough)

The ZX10R is about 2mm above curvy stock from memory without measuring it

stock curvy is 337mm, zx10 is 338mm, pointy is 330mm going by the table that someone posted

hmm know what my next "cheep" shock upgrade will be kwack atack near on perfect (would be if it were 5mm longer)

i measued both shocks from top to bottom bolt hole on both shocks in exact same place and standard was 2mm longer, battery box took some hacking and then some more hacking and a little bit more, battery now rests on top of reseviour and i will be looking to make up something that looks more professional to hold the batt along with a slightly smaller battery.

Hi all.

Looking at the list of available upgrades for a curvy rear shock below, the shock that would work best for me is either one of these, due to better spring rate and shock length.
04-07 ZX10R 338mm 540#

03-04 ZX6R(636) 340mm 540#

Are there any other shocks that are easily available that are at least as long as the curvy original that has a better spring rate? Been looking but ita a minefield for me who doesn`t know! Would the 96-99 GSXR750 345mm 375# be no good due to the spring?

It would be far too soft.

That said I'm wondering how accurate the spring rates in the spreadsheet are. I have a ZX10R and a ZXR1400 shock and the springs have the same wire gauge, number of turns and diameter, yet the spreadsheet suggests there is a significant difference in spring rate (465 vs 563).
