So looking through the various threads I can’t be certain but I think you have the correct spring size and the needle bearing is applicable. I think you’ll need to compare the spring you buy side by side with standard to be sure on collars etc it seems there’s variances in ID. The collars I bought could’ve been a little thicker on mine but they’re fairly snug. Post up your experience if you can that way others will benefit.

This thread on page 6 has some details on some PU bushes and a needle bearing thatll fit your 08 shock. https://www.versys.co.uk/index.php/topic,14119.50.html
Thanks for the help man; I appreciate it.

Sonic Springs wanted $415 to revalve, powdercoat and install a new spring/collars - so I figured I can save a few bucks if I buy the pieces myself, and do the powdercoating, and some of the install.

Did I read correctly that you just popped the R1 bushings out and these popped right in? Is there no machining needed to the eyelets?

I ended up purchased these two bushings, hopefully these work;

M12 Spherical Plain Bearing, ID 12mm Hole/Bore, OD 26mm, Teflon Lined (GEK12T)

I also saw you said the coil I linked would work but saw you used; Eibach model number 600.225.1100. 6 inches long, 2.25 inch 1100Lbs

I found an Eibach that should fit the 2008, that's 7 inches long, 2.25 inch 1100lbs (https://www.ebay.com/itm/Eibach-0700-225-1100-Coilover-Spring-1100-lbs-in-2-250-ID-7-in/382945001826?hash=item59294d0162:g:0woAAOSw1oJdC7Mo)

Do you think the Racetech colliers you purchased will fit on this shock? (how did you get the old coil out/new coil in? --> cheap spring compressor or a professional)

I'm really new to shock rebuilds, and bike builds in general so input is helpful.

Happy to help!
I would measure the eyes of your shock with a vernier calliper to be sure. On mine the bottom eye was 25mm and the top was 24mm. Yes on mine they pressed out and in without any drilling or boring. Mine might be different to the 2008 though. I’d have to read the thread again to check what’s written but I know for sure the roller bearing is correct because I bought it based on the thread about the 2008 shock. The spherical @26mm doesn’t sound right....correction I just checked and that’s what I bought....it fit, so I must be wrong about the eye being 25mm..I just checked and indeed it’s a little over 25mm

For the bushings removal I just used small dental style picks to remove the grease seals spring clips et . Be careful not to damage or lose them like I did or you’ll need to buy new ones, like I did. I used a big vice and various sockets to press them out

For the spring, I used a large vice to hold the shock steady and cheap spring compressors to get the old one off and new one on. I bought some eBay $20 jobs link below, but they are flimsy and it’s sketchy af. I used a set of vice grips to clamp the spring compressor channel as the tube was bending out of square as I was tightening with a ratchet. The vice grips helped to get enough leverage on the piece as well. I put some oil on the compressor threads as well so they wouldn’t seize up.
I also used a small ratchet tie down strap wrapped around the spring and compressors to keep the compressors aligned as I tightened them down.

This isn’t safe but I made it as safe as I could. Keep your fingers away and use needle nose pliers to grab the retaining collar

did you look at the second post with the Eibach spring?

In addition, the shock I purchased, turns out has 20K miles on it; do I just need to revalve it or is rebuilding it needed? I already got a new bumpstop for it as the old one was weathered.

--> However, I have the opportunity to buy a 09-14 R1 Shock with 4700 miles for $70.

Is keeping the 2008 and working with that okay (20K) or should I save myself hassle later and get the fresher one?

The eBay seller isn't accepting a return but eBay customer service said Paypal can make it happen if I need it to

As far as I can tell that’s the correct spring for my bike my weight 82kgs +some gear...it gave me a spring rate just over 20kgs/mm
Go here, plug your numbers in and it should tell you which spring rate to get

https://www.racetech.com/ProductSearch/12/Kawasaki/EX650R Ninja 650/2006-19

In terms of 7 inch long 2.25 Id say that’s correct.
The collars were for my own peace of mind. The spring will be loose on the shock retainers otherwise. This was my preference to buy them just to make sure @1179 doesn’t seem to use them and he’s still here... :)

1100lb is correct if I went the Eibach route; the question is more geared toward colliers for the Eibach spring --> do you believe the ones you used would fit the same?

Yes I have an Eibach spring. The question is will they be needed on the 2008 shock. I believe yes, from reading the versys threads

Ended up opening a case on paypal to return the 20K mile shock as it wasn't described and is not usable IMO - should get $60 or so back from this

- Picked up an 09-14 R1 shock with 4700 miles for $75 --> so now it being the same style shock as yours, the bearing will still work, and I should just pick up:

- the Eibach 6", 2.25, 1100lb spring
- racetech colliers


How much did revalving cost once you assembled it?

So the EIbach spring is a little larger in diameter than the stock R1. Ive done some research and found some collars the are from racetech and they are part SBSC5855. Ordered 2 obviously, one for each end.

@1179 Did the Olin’s spring fit straight on?
On Racetech's website it takes me to a vehicle search (https://racetech.com/VehicleSearch) --> What bike are these collars off of?
