I have Ohlins spring, 180M/mm or 1028lbs (200lbs rider + gear) selected by my Ohlins dealer and verified by Kyle R. I don't have my notes in front of me but sag #s were perfect

Hmmm - it does strike me as a bit of reinventing the wheel. All very well to start fresh but it would be smarter for them to 'investigate' how a respected competitor set up their units first.
Still - good to see them doing this for what is a discontinued model.

....you stated in an older post, that you ran your 919 with a reworked rear shock? Im curious as to what spring you are running now?
Yeah....Think the issue is more the chasis design & squat charactistics of the 919 than it is Penske not knowing how to calculate spring rates. (I have a gut feeling Honda knew this....because the original '03 spring was a 1200.....)
|10-26-2010 06:23 PM|
don't get me wrong, Penske is one nice shock, but based on your posts guys I'm not impressed with their knowledge or the ability to educate a customer.
There is no freaking way you should use 1028lbs spring being 180lbs.
Ether their rates are off or who ever assist you doesn't know any better.
call this # guys, 831-394-1330, ask for Dan. He knows shocks and he knows springs, ask him to help you with the spring rate for your

You'll get different variations of setting your sag from different companies.....some are a little more accurate, while other methods get you in the ball park. Below, is the get it in the ballpark method. (The more accurate versions have you taking multiple measurements....recording the data, then averaging the data to end up with a single number)
Three things you have to do......
First mark a spot on your tail....can be an existing spot, or a piece of tape. You need to take your measurements from the center of your rear axle to your chosen spot.
- Figure out Full Extension.....lift rear of bike....tire off the ground preferably. (jacks under frame or 3 people, whatever is easier) measure axle to your spot. Record data.
- Static Sag, put all of your gear on, sit on bike (need extra people to measure and steady the bike.....I have a 'bike grab' to steady the front wheel and called my wife to the garage to measure for me....she laughed at me in my leather suit) measure axle to spot. Full extension minus this new number = Static Sag. Keep adjusting your spring preload until this number is around 30mm. (The more accurate variations of this are to....push down on the seat/bike --- sit on it, measure.....pull up on tail, sit on bike, measure --- average data to get one number)
- FREE Sag, bike back on the ground....push down on the tail, let the bike spring back up under it's own weight. Now measure axle to spot. Full extension minus this number = FREE Sag. It's basically, the amount the bike sags under it's own weight. You set the Static Sag first..... Free Sag is used to figure out if you have the correct spring installed. You don't want the Free sag to be less than 5mm otherwise the bike will be topping out at the top of the shock. I've been told 5-10mm is ideal (Penske said they shoot for 6-8mm).
Now.... the sure test after all of this is the Zip-tie methond...... put a zip tie on the shaft of your shock --- go ride your favorite twisty road the way you like to ride it. Stop every little bit and check the zip-tie...... You don't want to be bottoming out, or the opposite, which is not using a good amount of your shock travel.
When I had the incorrect spring installed (The 900#/in) ---- I had the Static Sag set at 30mm, which gave me 1mm of Free Sag.... did the zip-tie test --- and the zip-tie was constantly being shoved down into the bottom of the shock shaft. I did have the option of dialing in even more spring pre-load...... but this would have given me even less Free Sag --- which was already next to nothing.
|10-26-2010 05:44 PM|
That's one thing that will be completely gone......jarring bumps.
- start w/ 2 complete turns out of ride height
- shoot for 30mm of Static Sag, your FREE Sag should then be between 5-10mm
Don't pay much attention to the Penske manual you get with the bike.....it's sag setting instructions tell you to set the bike at a 25mm Static Sag.....which is hella stiff on the 9er.

|FlyCatcher||Looks like I have a lot of reading to do when mine comes. There is a lot to know when it comes to dialing in suspension. For me, the biggest thing is eliminating the back-breaking jar that I get every time I hit a bump. That shit is starting to hurt. Thanks to everyone for posting up all the good info here.|

Thanks for taking the time to check for whatever info there is handy.

I could put it on the shock dyno, but I am simply not going to go to that trouble LOL
I will however check the Ohlins world site to see if they happen to have charts already made
|10-26-2010 10:52 AM|
Do you the damping force curves for the Olins.
If so, how about posting.
I for one am more than just casually intrigued, as you well know.

Hard to say if the Ohlins would be a closer match out of the box or not. It would be awesome to do a back to back comparo of the Ohlins!!!!
I can say, without the ride height adjustments (that the Ohlins doesn't have), the Penske would be worthless. The reason being....if your now using the stroke of the shock like you should....the bike will have a little squat during acceleration which in turn is going to slow down your steering.
Unless you also redo your front end at the same time....you will absolutely need a little more ride height in the rear to make the 919 turn in the way it should.......
It took 3 complete turns out of ride height to finally get it all to work right....

|AllanB||Now you'll need to get a Ohlins from LDH and do a comprehensive comparison for us!|
|10-25-2010 06:27 PM|
Many should thank you as time goes by.

Ya know..... lately I've been having a 95% success rate at the UPS box interception.
God bless secret Paypal accounts.

Wow ---- I called Mike this morning and dumped all the information on him. Did a chit load of testing this past weekend...... went through 3 different static sags, had multiple ride heights changes...... Alot of miles messing with Zip ties.......
...... Glad to hear they took our advice. Basically, the last thing I said was --- That 900#/in wasn't working for me and my testing was done at a medium pace....I would go as far to say that I wouldn't install the 900 on ANY shock that is going to be installed on the 919.
Good to hear their using our information!

Available and purchased as of about 2 minutes ago.
The wife is gonna have to start workin some overtime to pay for all this. Between this and the PCIII I'm down another $810 to this damn hobby...correction...lifestyle.
1000#/in. spring is the standard now by the way
Again Arctic, thanks for the heads up about this ...I think

See the attached.
First is what my Penske was like out of the box in 2 way configuration.
Second is what my Penkse was like after being reconfigured to a 3 way.
You will get a shock dyno curve with your new unit.
I'd really appreciate you posting it so I can compare to what I have.

.....they will not build you a normal 8900e for the 919 anymore.....they upgraded it to work better and will probably be called something else. It's a version far closer to a full blown 8983. Like the other Penske shocks, it is fully upgradeable to the 8983 at any time.
This new version is available now to us 919ers....
|10-12-2010 10:56 PM|
|AllanB||Ah so are you saying DO NOT buy a 919 Penske until November?|
|10-12-2010 09:05 PM|
|10-12-2010 07:56 PM|
Excellent! Mike is a great guy.
|10-12-2010 01:13 PM|
mmm... not sure I can swing it ($$$) but very tempting.
I'll definitely mention your name
|10-12-2010 01:11 PM|
.....might as well get the new resovoir upgrade that Im receiving....
Drop my name to Mike.....(Brad - WristTwisters)
|10-12-2010 01:10 PM|
+1 on the detail curiosity.
I'm considering shipping my newly acquired (but used) 8900 back to Penske for evaluation and possible rebuild for my weight before installing it.
I'd like to have it mounted up by spring.
|10-12-2010 01:05 PM|
Ya know.....got so excited about the new shock, forgot to ask Mike....lol. I trust 100% that I will be taken care of....and if it's not right, they'll for sure make it right.
I'm blown away by the service you get with these guys.

So.... I'm pleased to announce I just heard from Mike Himmelsbach today from Penske. Its taken them about 2 weeks to build my Penske 8900E.....
Have some awesome news to share with everyone.....
--- Penske, because of this thread has received multiple inquires asking for information in regards to the 8900E on the Honda 919. Because of these inquires.... they decided to re-evaluate the design of the 8900E on the 919. Penske apparently in November will start making a higher-end version of the 8900E, which will have a seperate remote resovoir. Thus, the shock will hold more oil and apparently be a large upgrade over the standard 8900E.... In the end.....this new shock will also be cheaper to upgrade to the 8983/triple clicker in the future. (assuming you will ever need to upgrade) This shock will have a custom spring, ride height, rebound, and a remote resovoir with a valving setup for the 919. (just no compression adjuster) This is NOT a pre-built off the shelf shock.
So...... I will be the first person to get a version of this brand new custom built shock for the 919.
The cost will be in the $600ish range.....this shock can be ordered through Mike now at any time.
---- expect install photos and a new thread/report in a week or so....

Are those guitar cases (with motorcycle stickers on them!) in the backround, or suspension cases?

The present rear spring is 1,100 #/inch.
The shock came from Jim Lindemann with a 1,000 # /inch spring. I found it soft, especially if you want to run the back end with a soft top out by virtue of a 10 mm Free Sag. It was also soft with my wife on the back and most of my road miles are with her on the back.
I changed it to a 1,100 #/inch which was better.
I am going to try a #1,200 as an experiment but won't go higher than that.
I'm running a 0.925 kg/mm front spring rate.
Our track is very bumpy, I mean REAL bumpy.
|10-06-2010 06:11 AM|
|arctic954||What's your total weight? What rear spring are you running for curiosity sake........|
|10-05-2010 09:40 PM|
When the shock arrives, there should be build sheet and shock dyno curve with it too.
My guess is that they still use the Hypercoil springs, and the spring rate may be faintly painted in white on one of the coils. The rate is also etched on the ground flat at one end, but you can't see that without taking the spring off.The spring rate should be on the build sheet too.
Once you know the spring rate, please post it.
