What a difference a day makes! Had the progressives installed in 45 minutes and they make a very nice difference in rideabilty. Hard stops and aggressive cornering are especially improved. Well worth the $75. Springs themselves are about 2" longer with double the number of coils, 3 5/8" spacers instead of 6" factory gives about an extra .5" of preload. Highly recommended for those of you who were thinking about it.

Did you install just the fork springs and not the rear shock spring?

Assuming that the front and rear progressive springs a matched, I am wondering if installing progressive on both front and rear will make the most difference.

Are the springs you installed from HyperPro?

Chuck,
I only installed the front springs, from Progressive Suspension, Inc.
I found the front very soft and undersprung compared to the back. I'm pretty happy with the rear after taking the time to adjust rebound and damping to my most common riding pattern, which is fairly aggressive, but still a daily commuter. Overall, I find the current set up very well matched and balanced compared to stock at about 30% the cost of the Hyper-Pro kit. :D

offpeak, can you give me some more info on what the springs looked like? are there different sections of equally spaced coils in the spring or is each coil a little tighter/looser than the one next to it? i ask because the pic of the holeshot springs showed discreet sections equally wound while the hyperpro seemed to be the other way. if this is what they really look like i'd say this makes the hyperpro's more "progressive" while the holeshots are sort of a stepped progression. what's the scoop?

thanks :)

Hyperpro kit

Hi Guys,

Offpeak I'm glad you like the new springs. It was the biggest drawback of the bike. I still wonder how everybody else goes on with standard fork! ;)
If they only tried one of our bikes they would realize!
How is the fork kit by Progressive Inc, is it really progressive?
Scott my Hyperpro kit was as you described, not equal spaces between the wounds. This is what makes it progressive, and it feels GOOD!
BTW Offpeak, the Hyperpro fork kit cost me around 100$ when I installed it ( fall 2000) and it included 1lt fork oil W15. It seems you got the price for the combined front and rear spring!
And it works without any extra spacers as described in the instructions. In fact I had installed PVC spacers beforehand and saw some improvement. This was discussed on the Garage, and it's the cheapest mod anybody can do to the bike (spacers and thicker oil). The fork kit though is something else. Malcolm and Chris know what I mean, now Offpeak found out also. How about the rest of you guys, are you really happy with the fork?

aris, i've got pvc spacers in with the standard springs now. did you really notice a big improvement from spacers with stock springs to the hyperpro springs?

BTW, i got a screen like yours. i'll be doing a review for the site in a week or two ;)

Hyperpro vs Spacers

Hi Scott,

I can testify that there is no comparison!
The Hyperpro kit transformed the bike. Specially braking and cornering is so much better. Comfort isn't sacrifised though as the first part of the travel is on the soft side and it stiffens towards the end of the travel. This way it takes the little bumps without upsetting the bike but it never bottoms!
How do you like the screen? Did you test it at high speed?
It's the best in my opinion as it does the job (if you put your helmet on the tank) without destroying the naked look.
Actually I took mine off a while ago as I wanted to enjoy the naked look once more, but I had trouble when I went for a ride with my mate (CBR929 RR) and had to keep it above 200km/h on the long straights. My neck hurt baddly as I haven't been riding much lately and I got out of shape!
There, the ZR7 can give you your everyday exercise!

Aris

PS. Scott, try the Hyperpro kit and you won't regret it!

Holeshot True Progressives

Hey guys,
The springs sold by Holeshot are "True" progressives, manufactured and packaged by Progressive Suspension Inc. There is a smooth progression from smallest to largest coils with out any "stepping" of the graduation into groups. Each and every coil is eaither bigger or smaller than the one next to it.
And yes Aris, I was reffering to the package front/rear price. Someone, Chuck, had questioned the logic of not replacing the rear shock at the same time as upgrading the front. I thought it unnecessary and expensive since I'm happy with the stock rear adjustability. It sounds like you agree.
HyperPro or PS, Inc.,? Both are true progresives and make a night and day difference in handling and braking performance as both Aris and I can attest.
Best bang for the buck so far in rideabilty change. Is one better than the other? Either is worlds better than stock.:D

offpeak, aris, thanks for the info. it looks like either spring will do well. hyperpro comes with 15w fork oil but it's cheap enough to buy that separately. i think the holeshots are a better bet for me because they are more readily available here in the states.

aris, i like the looks of the screen. it's small and keeps the naked flavor of the bike. i haven't been riding much since i got it installed because i had visitors in from out of town. i should be back in the saddle this week for some good testing :)

I got the Hyperpro springs installed about 2000km ago. They needed to know my weight when ordering them, so don't lie guys and you will get a spring that is suited to you and the bike. The new front gives you a tall feeling when first installed but settles down after a bit of riding.

They are totally awesome under brakes and for holding a line through corners. No more high speed weave while banked over. Coz we run wide bars you could never previously tell if the bike was weaving or the front was tucking, but the stiff front end eliminates the weave and gives you way more confidence.

Ditto the others, the rear is fine as standard.

Unlike before, now my ZR-7 knows that "apex" is not a club for the over 40's :D:D
