Anybody using hyperpro springs ?

Para045 · 11-04-2006, 10:26 PM

So I have finally received my 95 CBR900RR shock that I got of eBay, now I just need a spring rated for my heavy 130kg ( 300lb ) frame. After lots of checking on different threads it seems that getting one rated for my weight is the hard part, I seem to be down to either a special Eibach ERS 0600-225-1100 ( 6"x 2.25"x 1100lb ) spring that is apparently from their auto division or a Hyperpro progressive. I am waiting for the local suspension company to get me a price for the Eibach ( found one on LE engineering site but with postage and conversion she ends up at $ 260 AUD ). The Hyperpro distributor has quoted me $ 200 AUD for a Hyperpro but I am looking at 6-8 weeks wait to get one. Basically what I want to know are there any big guys with Hyperpro shock springs and how are you finding them and whether I wait 8+ weeks for my shock to be done or go with the Eibach ERS ( depending on price ). BTW I like the sound of the Hyperpro progressive springs as I think they may be a bit better in the way they work in regards to my bad back ( couldn't get much worse than the stocker ), I just want the opinions of some other large riders that have used the Hyperpro's.

I've heard good things about the Hyperpro springs, it will be my next purchase.

I have Hyperpro front springs, and I'm very satisfied. Highly recommended!

I am running Hyperpro front and rear. Here in Holland by far the best buy for that little money......

Hyperpro seems to have a good selection of springs, but talking about your back, you might want to ride bikes with the correct weight linear springs, and progressive springs, back to back (pun intended)...

If you're talking about bumps hurting your back, you've got to know the difference between linear and progressive springs (HP makes both of these styles, BTW)... The progressive springs will feel better over normal bumps in the road, but will have a much harder "hit" feeling to them on larger bumps, because, from what I've heard" the XX already has a VERY progressive linkage (which does not change with the shock), so if you're putting a progressive spring on top of a progressive linkage, you'll find it very plush just cruising down the highway, but will find it more harsh on larger bumps than a linear K-value spring. This is because, all the progressiveness adds up and you don't end up using all of your suspension travel to soak up the bumps. Large bumps were the only thing that some riders complained about with the progressive springs in the test that something Helvet is related with (company, or forum, I don't remember?) did comparing all of the brands avaliable in Europe...

Agreed (mostly)....
Hyperpro has a special progressive spring for bikes with a progressive linkage, which is less progressive than a straight-up lankage.
Yes, there were complaints about bumps, but these were with such speed and height that nobody in his right mind would ride on a standard Blackbird. Don't expect miracles from changing just the spring, the original shock is not a great performer, and will still be the weak spot in this.

The compairison-test we did was with the Dutch Blackbird Owners Club (B.O.C.) in (I'm guessing a little here) about 2002 or 2003. Only this year (2006) I became a Hyperpro dealer with my new company. Previously I was not committed to this brand.....

This is good information...

Yes, from talking to a support guy at the main HP in Europe (HP USA tech support was a joke) that Frank (Helvet) hooked up me up with, I also found out that most of the VERY harshness you feel when hitting bumps stems from the stock XX shock having a high speed compression rate that's pretty much through the roof, so all springs asside, you're not going to get rid of that HARD high speed compression damping (meaning, hitting large bumps). The only real way to get rid of that is to go to an aftermarket shock. I'm getting some help from the family, as a christmas present, getting a Type 41 HP shock with remote preload and a progressive spring, because it is adjustable for rebound and has adjustable high and low speed compression damping, so I can set it up for both solo (185lbs) and 2-up with luggage...

I'm sorry Frank, I didn't mean to imply that the test was biased... I've said that you were before, on the other forum, but you (Frank) set me straight on timing and your priorities, and we're cool about that now days. Again, didn't mean to take it that direction.

Thanks for the replies guys - after lots of emails and chasing around I have finally ordered an Eibach ERS 0600.225.1100 spring for my 900RR shock, I did like the sound of the Hyperpro progressive but after much searching I found that the Aus importers could get one for $200AUD + shipping to West Aus from Qld ( I guess ~$ 20 ) but as they only order this sort of thing as needed it was going to take 6-8 weeks to get one to them

, then it had to get to me

. Even tried the HP site in the US but after postage and conversion ~ $277 AUD

and a couple of weeks. Even to get the Eibach was ~ $260 AUD landed + 2 weeks

. After a bit of a wait on an email to the Aus Eibach dist in Qld they said to try a local car suspension shop that I have used before for my F100's and their price - $ 165 AUD, 2 days and about 20min drive to pick up sweeet

. Now to get the spring and shock to the Susdoc to do the rebuild/revalve + collar and then hopefully next week I can fit it and a 6mm shim
