« on: September 29, 2009, 12:08:27 PM »
Is there any difference between the two?

size, spring rate, length?

Yes they are different, the Gen II is a stiffer spring. Can't remember specifics on the others

Gen 1 is like a .82 and the Gen2 is like .89. Better but still a bit soft.

The fork is different, the brakes are completly different.

I am not sure if the spring is different but the spring rate is for sure.

Good luck getting any useful info from racetech. They dont know and why they dont have it on their website. I called them and they said they would call back after consuting with their tech dept and nothing. The guys said something about they havent dealt with one but not likely.

The information is on race techs web site now. Go to the search pull down menu, click on product search, select street, then click on hayabusa, then select 99-07 or 08-09 and hit continue. It brings up all the products for chosen motorcycle and gives you the manufacturer of the stock components and the stock spring rates. The Gen 2 has .93 kg/mm fork springs and 14.5 kg/mm shock spring. Gen 1 is .85 kg/mm fork and 13.1 kg/mm shock spring.
