Those are some good looking suspenders.

In the next couple of weeks I'm doing a DRZ rear shock conversion to my 2004 DR650. If that doesn't do what I'm looking for, I may be contacting you for a new rebuild. They look awesome!!

Sag and stuff on lowered DR

Stock spring 2007 DR650, lowered both ends. 175lb rider butt neeked after a good dump.

I just checked the static sag on the rear of the pig and it is 2" with the preload all the way wound up tight. Nothing left. I don't think the leverage is different with it lowered? Doesn't the setup just move the eye mounting in the shock and the spring on the same pivot points as the standard setup? That would mean the leverage doesn't change, just the "location or length of the extended shock? Same as a ride height adjuster.Basically putting a shorter shock in with the same spring rate?

This seems like too much static sag. Rider sag adds another good 2" or maybe a tad more.

31" fully unloaded
29" bike only
27" bike and rider, maybe a little less

perpendicular to ground on centerline of rear axle. Something seems weird?

More measurements on lowered DR650 rear

Almost all the preload out of the rear spring.....

31" unloaded
27" rider
28 1/2" bike alone

1 1/2" difference.

It is still a friggin pogo stick. High and low speed compression and rebound would be nice.

Sometimes pogo sticks are fun!

Using the shock in the lowered position puts the linkage in a different part of the leverage curve I guess but it really should not change the basic leverage. As the rear of the bike goes down, the weight transfers to the rear as well. When the rear shock is used in the "low" position, the spring clip should be flipped and that puts extra preload on the spring as well as positioning the big steel washer to restrict the shock travel so the bottoming point on the suspension is still the same (this avoids the wheel hitting the fender or the skid plate contacting the ground sooner than intended. This reversible spring clip is one of the reasons there is so many threads above the spring on the shock body.

If we build a short version of the shock, we can not keep the convertible feature. The shock is purpose built to give the low height and proper spring preload. Since spring rates are relative to the travel, reducing travel will make the required wheel rate be higher. In other words, the less travel needs a stiffer spring, all things being equal.

With regard to the DRZ shock, the new DR 650 shock is giving better performance that the Dz in Dual Sport use. I owned a DRZ E that was street legal up until last year and my friend Jerry (a DRZ s owner) has ridden on my DR with the new shock and wants me to make his DRZ work like the DR does. The adjuster on the DRZ is better than the stock DR but I really have no idea how it will work on the DR. Is the eye to eye length and stroke the same between the DR and the DRZ??

Was mine a white spring when I sent it? I can't remember. Too much of since I pulled it I guess!

I need to pull the Aprilia shock and send it to you some time..........

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!

Talking DR out of commision

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

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.
