Penske 8983 Double Adjust Shock 2002- 2012 DL1000

Not for sale any longer.

Have a low mile Penske double adjust remote reservoir shock. Compression, rebound, and height adjustable.
It has a 7"x1000 Hyperpro spring which is for a rider that weighs 260 to 290. I installed it today and cannot get my sag numbers to work. I have Two Brothers pipes which are about 20 lbs less than the stockers and I weigh 225 geared up. My bike does not have luggage. So I am about 100 lbs short of ideal weight. If you carry a passenger or a lot of gear with a combined weight of 300 lbs then this will work for you. Has all the paperwork manuals from Penske.

Product Features (8983 Series)

Remote reservoir
25 clicks of low speed compression adjustment
30 clicks of rebound adjustment
Spring preload adjustment
Ride height adjustment
Torrington thrust bearing to limit spring binding under compression and ease preload adjustment
Upgradeable to 8987 “Triple Clicker”
Fully rebuildable
100% designed and manufactured in USA

Price new $995.00 plus shipping.
Will sell for $600.00 shipped.

why not just put in a softer spring. 1000 pound spring is stiff even for a 265 poun d person.

you need closer to 700 pounds

Not sure where you got the 700 lb number at. I did order a 900 lb spring today for it so it is no longer for sale. The 7x1000 was for a 265 to 300 lb load. A 950 is for a 225 to 260 lb. The one I got is for a 195 to 225 lb load. Since I weigh in without gear at 230 now (thanks Thanksgiving!) I am going to be around 250 with a top box and riding gear on. So theoretically it should be undersprung with 7 x 900 lb I ordered. After talking to Dan today at Traxxion he thought an 850 would be too soft and a 900 would be just right. hopefully he is right I will know in about a week. The link is for 8900 series Penske shocks. You can scroll down to Suzuki. The lowest it goes is a 7 x 800 lb for a V-strom which is recommended for a 120 to 160 lb load.

I've done a lot of suspension work on both gen 1 and gen 2 V storms in conjunction with john sharrard, the best suspension tuner here in Canada. 1st generation with 180 pounds, spring ideal at 600 pounds. On gen 2 625 to 650.

there's a couple of easy ways to find out of the spring is right for your weight and bike. The easiest is this. Even before you try setting up sag etc with your hydraulic preload, measure how much static (or installed) preload the amount of spring compression when your hydraulic preload adjuster is at zero to get you to your sag numbers (on our bikes its 48 to 52 mm with rider aboard. If your installed preload (again hydraulic all the way backed off) is between 8 and 10 milliemetres you have the eight spring. if you need more installed preload than 10 mm (or your combined static and hydraulic preload is greater than 10 miles) to get to 50-mm rider sag, then your spring is too soft. If it's less then the spring is too stiff.

I've written an article about it which is somewhere on here. Also, ether's a gent I think named grimmer that does weight 280 or so and he tried I think a 900 pound spring recommend to him and could never get sag/the ride he wanted. He ended up somewhere around 800 or 850 I think. He also, if memory serves, rode with his wife or baggage a lot.

Are you talking about a spring for the stock V-Strom shock? Or would it even matter? I can tell you there was no way to get the 1000 lb on the Penske to sag correctly. To get only 38 mm of rider sag there was 25 mm of static sag and nearly Zero preload on the spring. I think Dan from Traxxion said good numbers for street are 10mm static and 40 mm rider sag.

by installed preload I mean you measure the spring. when it's off the shock. Then you install it on the shock and it's 10 mm shorter. So, say the spring is a 7 inches. It should be somewhere around 180-mils tip to tip. Then you use a spring compressor and after it's on the shock, 10 mm static or installed preload in other words, the spring measured the exact same way should be now 170-mm tip to tip you should get about 48 to 52 mm of sag from totally extended without any hydraulic preload.

Yeah a 1000 is way off. I looked at the penske numbers and that's a really long way from my experience. I had a 2002. Again, I am 180 and with about 12 mm installed preload (a little much but not too bad) I got exactly 50 mils sag. On my 2018 slightly different linkage ratio I have a 625 pound spring with exactly 10 mm static preload and I get exactly 52 mm sag with me on board. The chances of 1000 or even 900 being right for you when you weigh only 45 more pounds than I do are minimal.

And Big or do you prefer to be called Mr. Head? remember I am not trying to influence your ride quality, I am just going by numbers that are pretty standard in the in dusty. For instance I may disagree with Dan's assessment with your numbers I actually know dan a little as I have a Traction cartridge up front and I gave them a little help with v strom compression adjuster but 10 mils static preload and 40 mm sag is nit that far from what I have mentioned. And a long way from a 1000 pound spring.

Goof luck. PS, spring are pretty universal and a 7 lunch translates into a 180-mm if the shop is metric, so if penske won't sell you something soft enough, you can source elsewhere.

And One thing I found out is that lea the suspension adjust in the world my rear shock is a triple clicker as well won't make a bit off difference if you're not within one spring iteration + or - 25 pounds they can't make up for that much of a mismatched spring.

again good luck

if you looks at post 38 you'll see that grimmer started with a 900 pound spring and he ended up at 700 it seems or thereabouts.

maybe read the entire thread
