Im finally upgrading the suspension on the fxdx and would like some opinions as far as the rear suspension and upgrading the stock forks. Since this is a 99 it has the non adjustable suspension stock, and the forks had major brake dive. What are the decent mods while the forks are torn down? thanks for the i
nput!
No one asked and provided their choice which definitely would not be mine for sure. I do a lot of Dyna's and the questions I would ask would be
What is your inseam?
What is the length eye to eye you wish to sit at. You can do this by butting a jack under your bike, remove one end eye bolt each shock, than pull it away from any interference, than sit on your bike and adjust the jack until you find your happy place.
Ask yourself how you wish your bike to ride which is in direct proportion to how much money you are willing to allocate to your bike's suspension.
Do not rely on anyone's opinion here and rely on your own mind. Unfortunately there is so much bad information on the web and a very small number really do not understand how as shock works. Make up your own mind. Ask a professional how that brand works for you. Good luck in your quest.

Good assessment if the OP wants to work on the answer..
from the picture, looks to me your fork sits quite tall, and the shocks look like from the superglide, they're quite stiff rite?
i have got question about suspension sag:
data: 2004 fxdx odometer 20,000kms or 12,500miles, stock fork springs, 3year old progressive 13.5" 420s at the rear, mostly solo riding, rider weight 165lbs, new fork oil
here's the sag calculation i got
fork:
jacklifted off the ground 180mm, bike weight (unladen) 145mm, with me 125mm, so that would be 35mm for static and 55 for race sag.
rear:
jacklifted off the ground 305mm, bike weight 270mm, rider weight 255, its 35mm static and 55 race sag.
can any one explain to me about the figures above? i dont know whether the springs have gone soft or what..
i dont get bottomed out but i still feel the brake dive but not too much. the fork preload is set about 3 lines shown and the shocks (1-5 clicks) are set to 2 clicks from the hardest.
i needed to set the sag rite since i wanted to get the best compression and rebound adjusment on the fork. i've been trying to minimize the shimmy feeling (quite scary) from the front end when speeding up or in long fast curves...

Turbols1 my suspension upgrade plan for my 1999 FXDX includes the following:
1) Either Progressive Heavy Duty fork springs with Race Tech Gold Valve Emulators or a Race Tech springs with Gold Valve Emulators
2) Superbrace Fork Stabilizer
3) Progressive 490's or 970's for the rear suspension
I am a 290 lb. rider who rides hard and I need to have suspension capable of handling big hits. At nearly 300 lbs. with a need for speed, are the Progressive Heavy Duty springs on the 490's or 970's a good option for my rear suspension or will the standard rate handle 300+ lbs. geared up and performance riding up to possible track days?
