2005 YZ250 Suspension Help
Posted September 24, 2012 - 05:19 PM
I recently bought a 2005 YZ250 with very low hours, clean stock bike. I plan on riding woods style riding and little motocross - i would consider myself a competitive C rider (170lbs)
First ride i noticed the front forks were very harsh and bouncy, deflecting off everything, front end felt very light as well. I tried different compression settings and rebound and nothing helped.
I have read that the 05 forks are the main problem on these bikes and everything else is golden.
What i have read that could cure this:
- 22 mm offset clamps or lowering forks in stock clamps.
- Buying 06+ SSS Forks
- Having a re-valve done - spoke with a guy at factory connection today and he said he could make them better but they would never be as good as the SSS forks.
- I also have a GPR V4 Damper i would like to install but it seems that i have to buy specific upper clamps to use the damper ( which are not offset)
All in all it seems like a lot of work and money just to make the bike feel safe and more smoother. Im not looking for a factory suspension or anything like that. Just something that i can hang onto in the woods. I currently have stock KTM suspension and a RM125 (both stock) and they ride sooooo much better. I do love the power of the yz250 though (:
Any insight? Any help is great appreciated!

All those other options would just be trying to act as a band-aid for the incorrect suspension setup.
My 05 was horrific on sharp hits as well. I think if I ran over a golf ball at 20 mph it wanted to deflect 10 feet to one side or the other. Did a lot of work to them, most the issue was in the midvalve setup for me (forks weren't stock valved when I got the bike though).

They are a straight swap, cheap and once revalved are awesome offroad forks.
A little soft for moto but not too bad.
I read where Factory conection had the Open Chamber forks of the WR's/ earlier YZ's dialed for off road.

Now the 06+ forks are worlds better imo and I have had both. Seen some 06 forks in the classifieds for less than a revalve recently.

My revalved 05 forks work excellent and are better than stock SSS imo. They aren't quite as plush as the OC forks, but are still pretty good. They don't deflect at all and it's amazing how well they hold a line through the rocks compared to the stock forks. I took my steering stabilizer off to put on one of my other bikes and didn't even notice a difference without it.

One more question i have is: Triple Clamps? i understand there are a lot of aftermarket "offset" clamps for this bike, has anybody tried these? I have also heard that moving down the forks in the current clamps helps. Should i stick with my stock clamps or find some offsets?
I also will be mounting a GPR V4 Stabilizer and will need to make sure everything fits with that. Which it seems like a lot of brands dont accept this stabilizer for their top clamp?
Once again thanks for all the help everybody!
