Want to change fork springs



Hey all,

Looking to change the front suspension for better handling off road and on. Anyone able to point me to the best progressive setup?

Thanks,

TC

I went with Wilbers progressive springs and love the result.
Wirth, and Progressive also make springs for the 1000.
Sonic makes a spring also but it is not progressive.
Any will be a major improvement.

After tires, front fork springs will be the most noticable difference you can make IMHO.

How much affect will the tires have? (especially if you run the same pressure as before)

I got my Wee-strom (first motorcyle, first motorcycle I've ever been on period) and scared the snot out of myself.

TC,

At the risk of starting a religous war, I think it's the opinion of most suspension tuners that straight rate springs will give both a more comfortable ride and better handling than progressively wound ones will. A short explanation of why can be found here:

I recently install the Sonic Springs 0.9 straight wound spring and the recommended (by rich at sonic) 15w synthetic fork oil in my k5650.
I am extremely impressed by the change in ride quality and less front end dive when braking.
At first I was somewhat apprehensive of using such a heavy oil, when the oil that comes with the bike is only 8w. The only other improvement you can do is to install some cartridge emulators, which I have read good reports on. You would still need to upgrade the springs to gain full advantage.

cheers

I too just got my Sonic Spring .9 yesterday and plan on having them installed this weekend. How difficult was the installation and how did you support the front end while removing the forks?

installation was a snap. I just leaned the bike over abit and put a jack stand under the exhaust pipe. I also put a large vice grip on the side stand so it wouldnt fold up on me. I was actually very stable in this position.
Before you loosen your fork clamp bolts, crack loose the top fork cap. Makes it much easier than trying to loosen it once the fork is off.
You will also find that the front fender comes off easy if you first remove one of the forks.
It took me 1.5hrs to do the job.
It will take exactally 500cc of oil per fork leg, that is using the oil level measurement supplied by Sonic (for a 650 anyways).
I think you will be very happy with the upgrade.

cheers

Change Fork Springs

I do not want to start any battles either, however I upgraded my 05' DL 1000 with Race-Tech straight rate springs and Gold Valve with their recommended very lightweight oil. I must say that this set-up works best under ALL conditions-fast canyon road, offroad, smooth or rough. The gold value adjusted to your riding ability and spring rate to your body weight is an unbeatable upgrade. It is a little pricey, but to me its worth it....

Thanks for the info rcacs. A buddy of mine is going to let me use his full size lift, so I should be able to secure the bike by clamping the rear tire and lisfting it with a sissor jack.
