Hyperpro rising rate springs?

I have them and they make a big difference. One of the better mods I've done (and if you look at my sig, I've done a fair amount of mods). In the US you need to deal with EPM Performance out of New Jersey. They were very helpful.

I got the kit to do both my front and rear springs. The part number for the FZ6R is: SP-YA06 SSC 042 B (it's the XJ6 kit, but they're the same springs as ours). They cost me $289 this summer plus $25 to ship them to Alaska.

I couldn't be happier with them. Oh, and unless you want some odd looks, get the black rear spring. If you don't ask, they may send you the purple one, which is their signature color.

On a side note, the stock springs in the FZ6R actually ARE progressive rate springs. The Hyperpro are a better quality spring, plus I believe the front fork oil is a slightly heavier weight over the stock oil.

Your best options are the Hyperpro progessives or the Race Tech straight rate. Just getting the right spring rates, front and back, for your weight will make a big difference. Additionally, the stock fork oil is 5W, which is good for cartridge forks, but you need to go to 15W or 20W for our damper rod forks.

You'll be happy with either spring. The biggest difference is the progessives are much softer in the first 1/3 of the travel.

+1 on getting the right spring rates.

I've managed to try both Hyperpro and RaceTech springs. One thing that i did notice was that with the stock forks (no RaceTech Emulator valve), the progressive Hyperpro springs take away a bit more of the expansion joint hits on the freeway. My current setup is RaceTech valves in the forks, a HyperPro shock in the rear and progressive Hyperpro progressive springs all around. If i get to the track next year, I'll stick the straight rate springs back on.

I don't plan on doing much track/racing with it. I go on rides a couple times a month with some buddies though doing windies through the mountains. Thank you all for your input.

Ok, I'm getting due for a fork oil change. While I'm there I'll swap the springs and go with 15W or 20W, haven't decided yet.

I'm debating between Raceteck or Hyperpro progressive springs

Raceteck tool suggest me F0.95kg (+1) and R19.6kg Springs. Accordingly to my weight (and add few pounds for the luggage).

So what would you think be my best options? There about the same $$$

For what you do Marthy, I'd go with the Hyperpros. I think, if you lived in an area with lots of twisties or you took your bike to the track, Race Tech would be better, but you'll be really good with the progressives.
