Spring rates 06-09 Daytona 675
« on: August 02, 2018, 07:07:31 PM »
Does anyone know what the early Daytona 675 stock front spring rate is , I want a heavier spring in the front of my 2010 STR and a friend has some Daytona springs lying about.

I did some measuring a couple years ago - there are however variations in springrates as posted by different posters around the net, so it would be best to check the springs available to you. And you must also be aware of difference in free length between Striple R and 675 Daytona fork springs - it a couple mm and it would be best to check internal preload when fitting other springs and then make a spacer to suit, if necessary.

There are no markings on stock springs. You need to measure dimensions and then calculate the rate if you can't measure the rate directly.

Sounds complicated , do you know off hand if all the Daytona 675 springs are heavier than the street , I thought they might be as it is obviously more forward biased with clip ons etc

I would guess they are, but you still need to check the actual springs you are going to use and check internal preload if you want to do it in a controlled fashion - you can also just fit them and see if you like them, of course.

Thanks for your help and advice Ill wait until I get my hands on the springs and see if there is any way of doing a comparison between them and my own side by side !
