Aftermarket Twin Shocks Question

$200 sounds like a great price for a pair of shocks. There are also alot of things that you can do on your own to improve your suspension. Progressive springs, emulators, etc. Make sure the seals and oil are still good. I ride a 1982 Yamaha XJ Seca, and with those forks, some people have inserted pieces of PVC pipe to increase the preload. I think it all depends on what you don't like about your current suspension.

I used to have a Radian too, and I can tell you there aren't many options. Ikon Suspensions also makes a set of shocks that I think have adjustable rebound ... I think almost anything will be an upgrade. Make sure you change the fork oil, though. I can practically guarantee that it's never been changed, and you will easily notice the difference.

I really wished Race-Tech had fork emulators for it, but they wouldn't sell me any. Keep the bike going! I wish I still had mine, it's a great bike.
Hagon will build you whatever you want - just ask them. As a starting point, try spring rates that are half your body weight - so if you weigh 200 pounds, try 100 pound per inch springs, which will make the bike 'sit' one inch when you're on it( 2 springs @ 100 pounds = 200 punds, right?). Ikon are Australian Koni's, since the original firm stopped trading; they have adjustable damping as well as adjustable spring rates. Both are good.
I have Hagon progressive wound springs in the front and Hagon Nitro shocks on the rear of my Triumph. They work pretty well, make quite a bit of difference overall.
I had a ZZR 400 cc Kawasaki in Japan that had the stock rear shock wear out. I swapped to a Hagon shock I ordered on the Internet and it made the back end feel better by far. It was cheaper than the Kwak parts also... They are a good option, I would say.
I did that very same thing to my Seca. I don't know if they make emulators for bikes that old, but I know that a set of Progressive shocks improved things considerably. If they make cartridge emulators for your bike, I would think you should get them. The forks are kinda skinny to start with, and it'g got a nineteen inch wheel, which precludes most of the really good tires out there today. If it is just a love of this particular motorcycle that motivates you, then do it, by all means. If you are looking for a more capable machine, you might be better off getting something newer.
Works Performance and Progresive Suspension are 2 other companies worth checking out. They both make a fine product and have shocks for twin shock Yamaha applications.
Never used Hagon but I have put Progressive Suspension on a couple of bikes and the improvement over stock, especially old worn stock, is impressive. Get the base model 412's and you will be pleased. The fork springs are a good improvement too, but first change the old oil to the proper level and you will probably notice an immediate difference.
It seems like 75% of the chicks in SoCal have aftermarket twins.
It's a four... with dual shockies! ;-P


You mean "sweater meat" or "soupcoolers"? Perhaps both?

Around here, the high maintenance types seem to get package deals. Nip, tuck, stuff, tox and injection.

Then some of them get more teeth.

And a soon-to-be ex-husband to pay for it.
If your looking for a cheap set of replacements that will work for the average rider, do a search on Google for MDI Shocks. THey run around $100 a pair. They won't work if you want to run it on the track but for most riders they will work much better than old originals.
