exbee said:I finally found a shop that has a set of springs for my 93 KDX 250 but they are progressive springs. Does anyone have any experience with these? I would assume that any aftermarket spring is better than stock. The owner tells me they are 34-41 pound progressive rate springs. I'm not sure how that relates to kg/mm rating of other springs. I know my stock springs are straight-rate, how will the progressive rate act differently? Any advice would be appreciated.

My local suspension shop is looking into springs for me and suggested they could get Eibach to make custom springs for a little extra money. I already mentioned using a shorter spring with a spacer and they told me it was not a good idea...I forget exactly why. I know the complete KX conversion is the best route but for this year I'd like to just switch springs.
exbee said:Thanks for the help guys. I may try a shorter spring with a spacer then, there seem to be a few that have tried it with decent results.

The stock amount of travel within the forks is 490mm. A spring that is 3mm or 4mm shorter in distance does not require measuring for coil bind.
You should try it on yours Tom68. I think you will find it a lot better than adding air.
Unfortunately, far too many riders think this way.exbee said:I would assume that any aftermarket spring is better than stock.

We seem to feel the factory engineers are more clueless than any jamoke who manufactures an aftermarket part for their bike, or makes a part that will even remotely fit their bike, or any part they take off a completely different bike that can be hammered onto their bike.....
I've found that if you are going to replace a stock part on a bike, you'd best have a very good, and proven, reason to do it. Otherwise you'll end up with a bunch of mismatched, expensive pieces that work worse than the stock parts.
That was my entire point. :whoa:julien_d said:......................That said, you do make a valid point. Different does not always = better!
julien_d,julien_d said:Um, Have any explanation for the front of the KDX being sprung for about a 90lb rider while the rear was good for 160lb rider? The front springs in the KDX are crap, regardless of how infallible you think the kawi engineers are. The bike is unbalanced from the factory, any way you look at it!
