Question 2nd/3rd gen rear shocks vs. 1st. gen

Been reading up on the typical life expectancy of shocks, along with the aftermarkets available. It shouldn't come to anyone's surprise who's read my past rants about high prices that I was utterly flabbergasted at the price of a new OEM rear shock assembly (> $1000 for unaware newbies). The term "sticker shock" does no justice. Now, I realize In comparison Ohlins and Wilburs aren't that much more.

I'm not new to the idea of shocks/struts wearing out, and I'm a firm believer most OEMs install cheap stuff just to get the final product to the showroom floor, so obviously the parts will wear out sooner than later. What sucks is there doesn't seem to be a cheap aftermarket replacement like there is such as a Monroe or Gabriel for cagers. Of course, when it comes to BMW 2-wheelers, I'm starting to think I've bought an exotic, so even if there was a Monroe for the bike world, they'd still want a forearm for the BMW's application.

Putting aside the fact the available aftermarkets are so much better performing, I thought a used low mileage factory shock would be a less expensive alternative, and this brings me to my question.

How much different is the 2nd or 3rd generation OEM shocks from the first gen? Is it merely a different spring or much more to it? just looking at pics online they look very similar. I'm wondering if the newer ones would even bolt up on the earlier models. If so, how much could it possibly affect the ride in an adverse manner? Perhaps it might be an improvement, even if minimal. The main objective is to get the 1st gen bike to riding at least as good as originally designed, as economically as possible.

Any thoughts? Anyone else ever considered this and went so far as to try it?

Inquiring minds, aka cheap-o minds, want to know.

Re: 2nd/3rd gen rear shocks vs. 1st. gen

you can just replace the spring which is most likely all that is wrong, the stock springs are very soft and when loaded are quite compressed so perhaps the shock part of the strut is not worn out - only way to find out is to take apart - Hyperpro springs are a good option - but do both ends

Will this fit a 2000lt?

Bones, I have seen that listing. What I've noticed after visiting one of the aftermarket's sites is this is a standard strut assembly, whereas they mentioned and showed an electronic controlled strut, which was more involved/complex. Their product/service consists of rebuilding someone's OEM ECS with their better components while reusing the OEM's electronic controls. It didn't seem like too much savings over their competitors, considering what they're offering.

That being said, the '09 OEM standard strut does look very close to the '99/'00 part, but I wouldn't bet the farm solely based on a pic.

I found that the stock "improved" rear Showa shock on the 05 LT had about the same damping as the new Ohlin I installed. The spring on the Ohlin made all the difference. The front was more pronounced and I have since had it modified during the last re-build to soften the damping in the Ohlin front shock. I am sure they would fit all years as there was no changes made to the swingarm and frame over the production life of the LT.

That's what I'm talking about!
I figured someone at this depository of vast bimmer knowledge could enlighten us.
Thanks for the post.
