04RR Stock Fork Springs

I weigh 91kgs and after consulting the Race tech calculator it appears that the stock springs are suitable for a 67kg rider. I havent owned my bike long but was about to start changing settings to improve handling.
Am I wasting my time with the stock springs.
Interesting phenomenen the stock rear spring is suitable for a 97kg rider, why would Honda have wildly miss matching spring rates on either end?
My VTR was the same far too light in front rate and heavier in the rear, is it a Honda thing?

Those figures are specific to RaceTech, Honda may consider the springs to be set up for a different weight rider. And RaceTech probably don't make any allowance for carrying a pillion either.
Measure what your springs are doing to decide if you need lighter or heavier springs. It all comes down to how you - the rider - want the bike to behave.
I had to put heavier springs in my '98 GSXR but I've been racing the 929 on totally stock suspension with no trouble at all, and I'm over 100kg.

Re: 04RR Stock Fork Springs

Sounds good, so you think the stock springs should be able to be set up to suit me without a change. I am going to start making changes one at a time to see what I can be done.

It's entirely up to how you are riding the bike as to whether you can work with the springs you have.
I've heard guys of half my weight complaining the 929 springs are far too soft :-)

Re: 04RR Stock Fork Springs

Not sure why Honda selected the springs that way. Pillion? Handling? Front lower than the back sharpens up the the steering. The '06 model came with stronger springs in the forks, 1.0 kg as opposed to the 0.88 kg in the '04.
The '06 also had a softer spring in the rear. I think a lot of people complained of the harsh rear end.
A lot of people with '04 s do change out the springs for stronger ones. I'm 93 kg and my forks use almost 100% of their travel.They are away at the moment for some work which will include heavier springs, 0.95 kg or 1.00 kg
