I'm about to lose my 💩
Guys can I please get some help, I'm so confused and lost on my rear suspension. Is there a shock I can buy that is taller and fits perfectly on our bikes?

Doesn't the Ninja 300 shock bump it up a little under an inch? They bolt right in, and they're cheap.

What problem are you trying to solve with longer shock?
Do you really need taller shock or just stiffer? Pre-gen is 440-lb/in, new-gen/300 is 475-lb/in. The new-gen/300 shock is slightly longer at 320mm. For bolt-on shocks, check out my thread with measurements here: https://www.ninjette.org/forums/showthread.php?t=337292 Another bolt-on 320mm shock is this one (ignore photo, it actually has clevis lower mount: https://www.progressivesuspension.co...shock-kawasaki There is also SV650 and GSX-R shock retrofits, but requires machining of frame and shock to fit (in some cases, cutting fender & battery box). More involved that just swapping clevis on shock you already bought. Last futzed with by DannoXYZ; October 11th, 2021 at 08:19 AM. |

as mentioned elsewhere, just need to replace lower eyelet with clevis on shock you have. Take some measurements to know what you'll need using one of these: https://www.harborfreight.com/search...ity%20calipers- search for "6-in utility caliper"
Measure, then see if any of these will fit. Very all dimensions such as width, hole size, threading first. Note bottom shock bolt is not same size as top. https://www.speedwaymotors.com/RideT...ck,338936.html https://hawkmotosport.com/racing-bro...r-ea-r3070085/ https://www.winnerscircle.com/collec...ducts/all99331 https://power-barn.com/gazi-suspensi...tended-clevis/ https://www.ebay.com/itm/362892629966 https://allstarperformance.com/amp/s...cers-all99331/ https://afterdarkspeed.com/product/8...nt-adapter-kit Heck, you can even make your own using bar-stock from Home Depot.

It is longer, and has preload adjustment - plus they are cheap. Not sure about anything newer (300), but we installed one on our PreGen - and it was an improvement. |

Thanks for this info Danno.
What's the meaning of the column 'Reservoir Fit' (Yes/No)? Does it indicates if it fits in the EX250/EX300? I ask you this because I see the 03-04 GSXR1000 does not fit, but you still bought it? So, some of them are longer than the stock and will actually raise the rear of the bike, right? I had always heard that swapping to a GSX shock would lower the rear of the bike. Can these old GSXR shocks be serviced and rebuilt? |

I just copied that off from posts... kkim made I think. Apparently there's A LOT of work involved in adapting those. I'm not sure about lowering effects, that may have been from moving dogbone pivots around to clear wider shock?
Here's some other ideas for my other bike that's commonly done: http://vfr800rr.blogspot.com/2012/08...rsion.html?m=1 Also you can make your own shorter dogbones to raise ride height and increase shock-leverage. I made them from aluminium to save couple lbs on my race bike (stock length). |

I have been concerned about buying used shock absorbers so I went the long way and bought some new Chinese shocks I didn't check to see if they would fit. I checked out the thread describing the different shocks for the different generations and it was very informative. Has anyone had experience buying used shock absorbers? How does one go about choosing? I wouldn't mind going with the new gen or the ex500 or the one with the adjustable collar to put a stiffer spring.

Ex500 has softest shock out them all. Many of them install Ninja 250 shock as upgrade.
Again, what problem are you experiencing that different shock would solve? Wouldn't be that difficult to remove clevis from 250 shock and install on your new one... |

What happened to that chain?
I have a newgen rear shock on my pregen 250. It made a significant difference in reducing sag. With gear I weight about 185, and the stock shock would bottom on large bumps in the road. The newgen shock does not bottom on bumps. It was $25 shipped from eBay. |

Jay, I would say that most folk on here have experience buying used shock absorbers; I certainly do. It's nothing to be concerned with. As a matter of fact, buying an unknown Chinese shock would be much more concerning to me than a used shock made by Kawasaki specifically for our bikes.
The reservoir on the piece you bought will hit the swingarm, so a new clevis is not going to help. It does not fit, period. I would return it and buy a 250 or 300 shock off ebay as Jim suggested. 250lbs is not too much for either of those shocks and either one will bolt right in.

The first problem is going be that is look like the reservoir is going to hit the swing arm. Just go be back to stock shocks and need beefer spring to better suited for your weight check round or read this page |

The bike had sat outside under a carport for a year and in my area we usually have morning dew because of the humidity. I scrubbed off some of the rust on part of the chain and it looks pretty much brand new. I had the chain installed and perhaps put about a couple thousand miles on it before someone stole my key and I had to keep it parked.

Thank you all very much. I have learned quite a bit and look forward to grabbing a new gen shock from Danno.

- coil-spring with smaller wire-diameter is softer - coil-spring with more coils is softer So result would've been this new shock would've had more sag than worn-out 250 shock. And its lower spring-rate would have you use up all suspension-travel and bottom out even more often over bumps! The new-gen 250 shock I'm sending you has one less coil than pre-gen, with thicker wire-diameter for higher spring-rate. |
