HyperPro Springs installed

[pkoosa]

The kit comes with fork springs, 15wt. fork oil, and rear spring. Instructions are included, but I used the factory service manual. Installation was straight forward using the manual. I took the rear shock to a local motorcycle shop that swapped the rear spring for $5, because I didn't have the right tool to do it safely.

Stock OEM Spring on the Left, HyperPros on the Right and uses the OEM spacers.

Front forks raised 10mm. (hyperpro recommended 5mm in the instructions)

Rear spring. The heft of the HyperPro spring can be felt compared to the OEM.

Nifty chain/wheel alignment tool.

I'm 215lbs. with gear and don't have a lot of miles on since installing the springs, but the difference is night & day.

very nice kit, where did you get it from?

What is the reason for raising the forks? Do you have any pictures showing how much lower the bike sits?

 

[CrazyBiker]

How much for the rear spring? $5 installed is too cheap man.

And how much?

Also, how much fork oil are you supposed to put in each fork? I've been contemplating doing front springs but I am too lazy to try to find this out...:spank:

I was going to do this whole thing, but opted not to lower the bike after
GMD Computrack talked me out of it. He said the overall geometry would
stay the same, but swingarm movement and angle would be changed and might alter the handling. I'm not going on a track, but I love how this bike handles and figured I just get a lowered Corbin seat or something. I'm really interested to hear how it affected your ride, if at all. GMD also told me just putting in springs and new oil would not help my problem. I just put in new oil and Race Tech .90 springs, and even without riding it the front feels a heckuva lot better, and doesn't bounce like a worn out car shock. If it would ever stop raining here in north GA, I'll be able to know how it actually performs. But, if your bike works out fine, then I may order that spring and lower it just a bit. Traxxion is telling me to get an Ohlins rear shock with ride height and more adjustments. Seems folks like me just don't have $$ for that stuff these days, thanks to all our money going to bailouts and such.

How much did that set you back?

These are not the "lowering springs", but the Regular height spec. There are 2 HyperPro kits available for the FZ6, Regular and 30mm Lowered. The springs are available separately or as a kit. I opted for the kit to have a matching set. There are other options available, but I found HyperPro to be the most cost effective solution for me that considered both front and rear of the motorcycle. $279 for the kit straight from HyperProUSA. http://www.hyperprousa.com/catalog.php?cat=Springs&make=Yamaha&model=YAMAHA+FZ6+04-08&model_name=YAMAHA%20FZ6%2004-08&springtype=Combi-Kit

I'll have to snap a picture of the bike from afar, but the height feels close to stock even with the forks raised 10mm. I did not take before and after measurements.

$5 was the labor the shop charged to swap the rear springs for me, not the cost of the spring itself. It took them less than 10min. to compress the springs for the swap.

Service manual specs the fork oil for each fork at 15.79oz. I can't say if it's the fork oil or the combination of both fork oil and springs, but the front end no longer wallows as it used to.

I'm thinking of buying these, especially for the rear since I don't want to spend $700 on an ohlins, but I want a spring that isn't going to bottom out or send every bump to my ass.

Too bad I can't buy the kit though since I have R6 forks and stock rear.

I had the rear preload on 6 with the stock spring, it's now on 4 with the hyperpro spring, but may go down to 3.

I'm considering to get the same stuff, but installed by the hyperpro guys,
costs 350 euros, so thats a pretty big investment, since I have no idea if I'd even notice a difference, so compared to stock springs, is it worth the money? does it add comfort? or less comfort and more stability??

Is there a difference? yes. Is it worth the money? for me yes it was. I feel that aside from good tires, good suspension is worth the investment. I feel I've achieved that without breaking the bank. Comfort is subjective. The ride is more complaint and reassuring.

Do you know what the spring rate is for the new rear spring?

Sorry, I do not.

Dang...I am really interested in this. I just wish they would post the spring rates. I know it's progressive rating, but hmmmmmmm. I am going to contact them and see what I can get back.

I'm going to go out on a limb here and ask if this is Patrick? ha-ha

I've been made, LOL.

Did you ask HyperPro why you should go with their springs (besides price point)? What would make them a competitive product compared to the ever popular RaceTech?

No, I made that decision myself based on everything I considered and for it's intended purpose.

I tried emailing them through their site, but kept coming up with an error. I will call them probably tomorrow, too busy right now. Just want to know what the spring rates are.
