    Ok.... Got the shock yesterday and mounted in the bike last night. Everything was buttoned up nicely, but it was freaking POURING out, so no ride last night, but even just sitting on the bike stationary revealed a HUGE difference in damping. The shock no longer acted like a pogo stick like it did before. I mean, it was a spring on a stick before, but now? Sit on the bike and it squats a little and stays there.

    Rick set the preload in the middle of the adjustment range and I did not even measure it last night, but it "felt" close. There is still plenty of preload adjustment left, so I have room to play with. My spring is stock and I weighed in at 178 butt naked this morning. Rebound was set at 20 clicks out, and I never checked the compression side.

    You can change the ride height with these also by loosening the nut at the bottom and screwing the lower mount out some and then tightening the nut back down, but you have to remove the lower mount bolt to do it. No biggie. I do not know how much height adjustment you can do here though.

    Rick also sent all the stock stuff back with it, so you have all the stock pieces if you want em for later too!

    Fast forward to this morning. Rainy out today, but who gives a shit, right? Throw on the rain suit and a cover on the tail pack and go. Now, I have a down hill gravel driveway with a 90 degree left and 90 degree right, and I noticed that I was not feeling anything. I mean, just in that short of a span I could see a difference! I hit the shoulder to the next road up and took off. Nice back roads most of the way to work that have decent sweepers that, if I want to, I can stay wide open most of the way. I kept it at about 70 to 80mph and enjoyed the ride, noting the different feel from the rear. Before, the rear tended to "track" a bit due to excessive movement and that pogo efect, but this morning? The rear was planted! I mean, I never felt a bump! The rear never wandered around "hunting" for a line. It just tracked nicely and felt great! I even took a short off road down hill excursion to the grocery store parking lot instead of using the road, and it felt great!

    I can't wait to try it off road now!

    Definately a nice set up that Rick has put together and once again, I can highly recommend Rick's services!

    ...Because the shock is in the mail and on its way to Rick! :clap

    I can't wait to see the results. Rick's KLR shocks are highly regarded and soon the DR will be performing to Cogent standards. :wings

    I'm getting one build for a lowered 2007 and will post how it works when I get it mounted. I can probably already guess what I will say.:D

    I had a race tech guy in chico do my DR shock and the reccomended race tech settings were way too stiff,very buckboard like but good for double jumping. He revalved it 2 more times at no cost,going a fair amount softer every time and it works pretty darn good now for a street oriented 350 lb pig bike. Seems like a big bike to try to get serious in the dirt on. But I am a long time single track two stroke rider so I may be biased.It worked really well out at death valley as long as I wasnt in the dreaded deep gravel bed full of big sharp rocks,the ft end seemed to plow and not steer much in the deep stuff. A knobbie in the back would have helped to get it up to speed and planing.

    Here is another review update........

    This evening on the way home, I noticed a couple things:

    1. My previous statement about not feeling anything on, in, over, whatever, the road, is not entirely accurate. I still feel bumps and crap, but only once! My front end is still stock, and I feel the bumps from the front, but the shock makes em just disappear out back! Amazing!

    2. It use to be that when running a set of switchback type twisties, that the suspension would load up and unload pretty drastically. In other words, the suspension would suck up in the corners, to the point of bottoming out, and then unload pretty bad out of the corner, and in a quick set of twisties, this unsettles the bike a bit, but now? This thing is stable as a rock in the rear! No drastic changes. No big time unloading or bottoming out!

    Now, after dropping Rick a line earlier, he confessed to me that he set mine up a little stiffer than most others since he knows my riding style, which is very aggressive. My recommendation would be to talk to the man and let him know your riding style so he can taylor the valving to your specs. In my case, he set this thing up just right, right out of the box!

    I also hit a couple trail sections on the way home and am happy to report that the bike seemed very well behaved there as well, but to be honest, I am recovering from knee surgery and am not aggressive at all in dirt right now. More of a stand up and ride the trails type of style at the moment, but it handled very nicely and was not abrupt in any way!

    So the ride height adjustment can lower the bike to equal the stock shock's lowered height setting ? That'd be cool because I dont ever see myself using the bike in the stock height setting. Unless I go to Korea and have that leg extending surgery I've heard about :lol3

    Thanks for the kind words Meansrk and thank you for the business!
    Eyedragaknee, your stuff is under control!

    VFR870, the stock shock has a high and low position, selected by the two holes (overall length) and flipping the spring clip (shock stroke). For me to provide the shorter stroke, I must shorten the shock shaft. On either version of the shock, the ride height adjuster only provides a VERY small range of shortening but will lengthen either. The short version can be returned to close to the stock ride height and the long version can be raised by an inch or so. The shock stroke can only be changed by opening up the shock so to convert a short shock to a full travel long shock it is likely that the shock will need to be returned to our shop. To add further clarification: the Cogent shock has the same stroke and length as the stock shock in either configuration but you loose the ability to fully convert it in your garage (at least for most people).

    Thanks for the info/clarification, Rick. My (lack of) off-road skills cant outride the stock shock yet but I plan on using the DR for longer road trips as well and I'm sure your shock will help with a loaded bike in the twisties. Your shock is on the short list of mods I'll get to as soon as my pocket allows :D

    Got the rebuilt Cogent rear shock from Rick in N.C. today and put it on my old DR 650(I sold it to my friend a couple of months ago).

    Rick did a great job. The bike now has a very good rear suspension. IMHO this is the way to go with the rear shock for the DR. Now I wish I wouldn't have sold her! :cry

    Okay, anybody else have any first hand experience with this shock? Just picked up a 2000 DR650 and want to get some suspension work done!!

    Thanks,

    Thanks P-Nut. Now just need to get a few more people to send their shocks in so NC Rick can get another batch going so I can enjoy one!!

    Thanks,
    Jim
