Need 929 Rear Shock Spring Advice.

So I have a set of .95 sonic springs on the way for the front and am now looking for something to match up with them for the rear. Not doing the re-valving now, just the springs.

So here are my specs.

I weigh 250lbs, carry luggage, prob 50-60 lbs of stuff at times plus the weight of the bags, and ride 2-up some as well.


This is the text from the email I got from Traxxion Dynamics.

think I have a spring that will work, I would need the ID and free length
measurements of the spring. What year is the VFR? Our recommended spring for
the 929 is an 850, and for the VFR is around a 1300lb, depending on your
weight. We sell Hyperco springs, and they are $100.


#1 So what is the ID and the free length of the 929 spring?
#2 Does anyone have any recommendation on what spring weight to get?



So my total cost in the end for the springs, shipping, and labor cost to a local shop to switch out the rear spring is $240. Not bad. I will be doing the front springs myself.
Re-valving may come next winter.

Thanks so much guys.

That 1300 lb(23kg) is right in the ballpark, I'm running a (1100lb) 19kg/.95 combo and weigh 190lbs.
So at least a 21kg up to the 23kg. (kg = 56.1 lb) :thumbsup:

Now I just need this info and I can order the spring.

#1 So what is the ID and the free length of the 929 spring?

Free length = 6 7/16 inches
ID = 2.250


Did some searching and wondered if this is correct for the 929 spring.

I'd like to know that part#. I have a 929 and I'll measure it tonight. How hard is it to replace the spring on the shock? I plan on doin it myself.

Here is my latest email. They do not seem to have the size I am looking for and they also do not have a spacer to sell me to fill the gap.
HERE IS THE LATEST EMAL

Ok, I have a 6" spring in stock in 1300lb. You may want to check and make
sure that you will have enough threads to put a little preload on with a 6"
spring. With a spring that heavy you will only need to put about 4mm of
preload on it. I can order a 7" spring if you think that will fit better.

Thanks,
Dan

Looks like I may look into another spring company for more options. Anyone have any recommendation on a different company to get a spring from?

Yes, Ohlins USA, 703-C Old Spartanburg Rd, Hendersonville, NC 28792 828-692-4525
$98.95 plus shipping and will have or can get exactly the one you need, Not a 6" or 7". <_<
You might be able to get away with the 6", but won't have most of the preload adjustment range left if any.

You should ask Traxxion if they sell spacers for the springs. You could get the 6" spring and then make up the 7/16" with a spacer. And I would not go with the 7" spring.

Sorry but take a look at the thread that you quoted. I asked them for a spacer and they do not have them. Thanks though. Looks like I will be following your lead B. Thanks for all the help guys.

Crazy!!!!!!!!!!!! This is maybe just 30 minutes north of me. Looks like I may be going straight up to see them. Putting in a call in the morning. :thumbsup:

Sorry! no disrespect by the post about the spacer. Just pointing out that I mentioned it before.

Latest update from TD: ---...---

I only have 1" spacers.

And as for other companies, I'd recommend GP Suspension: http://www.gpsuspension.com :thumbsup:

You can also check out Lindemaan too. http://www.le-suspension.com/ I had them set the suspnesion on my bike once.

Thanks so much Bling.

I went from racing cars which had a complete suspension setup tuned to my liking too the vrf which has a suspension not to my liking. Wish I would have done this sooner. In all I think I have learned a lot about my VFR in the first year of ownership and look forward to the next year. I think it is time for some HID lights. On to another post. :unsure:

Go to hprworld.com (or is it hrpworld.com). They are a Hyperco spring dealer. A Hyperco spring is a Hyperco spring regardless if it's on a VFR or an Outlaw sprint car or an Indy car.

Their selection is huge and they sell them all day long at $66.95 + $8.95 to ship. Bought a bunch from them. Great service.

Got my front .95 sonic springs on the bike today and can easily see that the rear is going to have a hard time keeping up until I get the new rear spring. Also got the blue LED dash light in. :thumbsup:

Did you talk to Ohlins USA yet????????????

Sent them a few emails but no reply. I think I will take a ride up to their shop after turkey day. Sometime next week. So far all of the replies I have is to send in the shop and they will put on a spacer. FINGERS ARE CROSSED FOR oHLINS. i AM SURE THEY CAN TAKE CARE OF ME.

On the phone with them now, looking at this exact setup. They are transferring me to a tech that comes from a honda background...?

Call them, 828-692-4525
Looks like a 1092-65 is close to what you need if I read this right? 6.7 x 1200 lbs :warranty:
here's their spring chart!
[image: Posted Image]

1092-89 is the 1200 lb spring. I dont know if that will fit. The 1092 is 6.7" stock is 6.4. I know the 1091 that is 6.3" would work but highest spring rate on it is 11.21Kg. Stock spring rate on the 929 shock is 15.3Kg. So the 1092 is the only viable option, but will it fit?

Has anyone ever re-sprung a 929 shock for a VFR?
If so what spring fits?

The guy at Ohlins reccommended not going more than 3 steps up on spring rate from stock. The springrate can overcome the valving and cause issues.

Assuming the 1092 fits, then I'm gonna try the 1092-69 (17.32Kg) or the 1092-74 (18.34Kg)

BTW I wish I had redone the valves on my forks now because going from factory .74 to .95 is a big jump & is overwhelming the valves a bit.

They don't make a 1091 in more then 650lbs so that won't work!
You might be ok preload wise using the 1092 and starting on the #1 preload position which will already have an extra .4" preload on it from it's extra length. :unsure: I would use a 1092-74 or 79.
Ideally re-valving for the bigger spring would be best, but you might be able to control the spring with the stock adjustments. :thumbsup:

I think a 6'' spring could work as that is only .4" shorter then required and I'm sure the pre-load adjuster could easially make up for that and your using a much heavior spring which should require less pre-load. :goofy:

Now the problem is HTF do you get the spring off. I have access to a spring compressor, but it pushes down on the split rings that hold the spring in place. So once its compressed the split ring is squished between the compressor & the spring and cannot be removed. If I use it from the other end its still under too much tension. I need a compressor that works from the outside of the spring. Those things are dangerous as hell too. Do they make a special spring compressor for MC shocks that grab the spring from the outside.

I think Elka or Ohlins may be the way to go now :goofy:

I usually get my rear springs from eshocks, they are between $72-80 each and I don't have to deal with Max who is a ripoff artist from the word go. You can also get a Penske built for the VFR, they custom build all their shocks. A friend of mine who has a FZ1 is getting a penske double clicker from JD Hord for about $750. JD is a rather infamous V twin race motor builder but he had about the cheapest price on a Penske my friend could find.
