Fork Springs for 250r and TriZ

[Ryah]

Does anyone know where I can get some HD replacement fork springs for a 1985 250r or 1985 TriZ? I have made PVC spacers to preload the front springs some so it doesn't nose dive in the dunes. I'd really like to upgrade to a much stiffer spring that wouldn't need the homemade spacers. Anything stiffer would be a much welcomed improvement, especially on the TriZ.

Thanks, much appreciated.

Cut out the middle man..... www.ProgressiveSuspension.com Infact, I think it seems like the 350X set also worked in the 83-84R. Either the 350X set or the 82R set also said Tri-Z was another application... can't remember which one! BikeBandit.com had them on sale last summer for $62 a set.... well worth it!

Thanks again for everyones feedback. 350x' in NY, I see that you are running these progressive springs. Are they quite a bit stiffer than the stock ones? It's hard to compare when I cant find out what the spring rate is, so my best luck is just seat of the pants feel from people that are currently running them. Most of the time the dunes I ride in are track free (lucky me! :) ) so full travel is not really an issure most of the time. But, like I mentioned I have spacers that are pretty long to keep the front end from diving. There are plenty of spots where the front tire will sink up to the rim lip, this combined with speed and heaven forbid a sharp turn makes for some pretty sketchy moments. I'd welcome feedback from anyone that is running these. The fact that they are progressive may be a problem if the soft travel is more than an inch or two, by that time the front of the bike will have too much weigth transfer and I will be going over the bars. My father (56yrs old but rides like he is 18) just broke his collar bone this past trip due to the above situation on his ATC 250r and I'd like to avoid it if possible for him as well as myself.

another thing you might try is change out your old fork oil with a heavier weight oil in the forks. if you are going to put new springs in, if it hasn't been done yet, put new seals and swipers in your forks while you are at it. it will make the front end feel like new again along with a new set of springs.

I am currently running 15wt in both bikes. Would you recommend going any thicker? I'm 225lbs and Dad is 190lbs.

I'm running progressive springs on my Triz with 2.5 inch pvc spacers. I also used a little bit heavier 15wt fork oil, helped the handling tremendously. I'm a pretty good sized dude (About 230) and they are 100% better then how they were before, but I will probably add a little bit longer of a preload spacer the next time they are apart. I'm running a YFZ450 brake master cylinder which will really make that front caliper clamp, and even if I grab a handful of it the frontend doesn't dive an "pogo" around like it use to. Now my only problem is since I went from a 25inch front tire to a 23.5 combined with the 18in rears that my frame bottoms out before the suspension does :p I guess I need to move the front forks back down in the clamps some and see if that'll help.
