Suspension upgrades (Forks, emulators, springs, fluid, brace)

For sale is a complete front suspension upgrade for the GS500. These parts are the best available for production GS500 race bikes and street riders wishing to retain the factory instrumentation and headlight. The springs provide a much more controlled ride, especially for heavy riders. Emulators make the suspension plush over harder bumps, yet firm under braking and cornering.

Included in the kit:

1. Stock GS500 fork bodies, modified for Racetech Emulators ($200 on ebay, plus labor to disassemble, modify, refresh, and reassemble.)
2. Racetech Emulators ($170 new)
3. Racetech .85 springs ($110 new)
4. 15 weight fork oil, replaced 6 months ago (5 days of use)
5. Fresh fork seals (replaced a year ago.)
6. Billet aluminium fork brace, by TheBuddha.

Fork bodies are straight, and in relatively good cosmetic condition. They have 4000 miles of street use and a season of race use. At last inspection, the fork brushing were in like new condition.

Racetech generally recommends these springs for race use and somewhat heavier street riders. However, .85 kg/mm springs are a very popular upgrade on GStwins, and I've heard positive comments from 170lb riders. Whatever you weigh, they are a huge improvement over the stock springs. I am more than happy to re-spring and adjust the oil weight/level, for the cost of parts.

I am not willing to part out the emulators or springs - the forks have to be modified to accept the emulators, and are useless without them installed. If you'd like to save a little cash, buy the complete unit, and sell your stock forks. Doing so will save you a lot of time and money. :)

Asking $400 for everything described above. If you're interested, I can also include a stock fender, and a triple clamp that's been drilled to remove the factory ignition. Combine with a R6 or Katana rear shock and BT003RS tires for the same setup that put me on the podium in 500 twins.

Iam interested in your forks as mine have no oil left in them and need to be fully overhauled , also need the springs to be stiffened up as well . How much would freight be to send them to aust , Brisbane , Qld

I'd have to check with the USPS, but generally I'd expect to pay $50-75 in shipping to AU. If you're interested, I'll package them up and get a quote.

That picture is freaking awesome....Sorry I'm not in the market, but I couldn't pass up commenting on it!

Sorry I'm not in the market either, your picture is awesome, but I'm curious...

What's that small bottle with two hoses on the side of your engine for?

burning1

The bottle is required by my race club. It catches any fluid that might overflow from the fuel tank. I get a lot of comments/questions about that. Hmmm... Would be fun to replace it with a alcohol container. :)

The forks totally change the character of the bike. Hard to imagine how good they work until you've tried em. :)

Sale fell through, due to the cost of shipping to the AU. So, these forks are back on the market. :)

Well, thought about it but was advised not necessary unless I start racing so I'll just replace the springs on Trey.
If you still have them after a while, let me know.

Bloody shipping costs  :cry:

burning1

Yeah, no kidding. On the plus side, you guys have a more readily available supply of RGV parts. I had to pay ~$150 to get a swingarm shipped over. :(

Price with shipping to Downingtown Pennsylvania 19335? Interested.  The seals are leaking on my forks right now.  I got a price of about $200 labor for changing the seals plus the cost of the seals themselves and I know I should really upgrade the springs also.  This would allow me to pretty much bolt and go correct? few hours of labor on my part to bolt them in... problem solved. Is there anything I would have to do otherwise to put them on a gs with stock triples? Also, I am a 175lb rider running 05 SV rear shock and 150/60/17 rear and stock front tires FYI

burning1

It's a bolt on upgrade. You'll have to remove your front wheel and brake calliper to bolt these in, but you won't have to do anything special otherwise (no need to disassemble the brakes, or remove the handlebars.) These forks should be a pretty good match for your shock.

I'll get you a shipping quote for the forks alone either today or tomorrow.

BTW... Was that $200 estimate to do the service on the bike, or is it if you brought the forks tubes in for service? If it's for the service with the forks off the bike, sounds overpriced to me.

theboy3443

It may have been $175. But yeah it was off the bike. All of that aside, I think it would still be smarter to do it right the first time with the springs and everything.  If I'm paying $250 installed with the cost of parts and labor, I may as well put the good stuff on there.  :D

burning1

Yeah, that's asking a bit much, IMO. Wouldn't take me more than an hour to do, off the bike... And that's without access to shop tools.

theboy3443

Maybe I'll try and throw seals in myself then? I'm pretty handy with a wrench actually, mostly with cars though.  Used to work on MX bikes alot, but never forks.

burning1

I may be talking myself out of a deal, but... If you're mechanically inclined, I think you could do the work yourself. Hardest part is going to be removing the pistons so that you can drive the fork seals out. IMO, the job is harder than an oil change, and easier than a valve adjustment. The main thing is to make sure you have the right tools; e.g. piston holder, fork seal driver (an appropriate piece of tubing works fine,) long allen socket, etc.

With that said, what you might consider doing is buying my forks for the internals. Rebuild yours at your leasure. Going rate on GS500 forks seems to be about $200, so you'd be out $200 for mine. Pretty stellar deal when you consider the cost of the components and the time and effort that went into installing and testing them.

Shipping estimate was $35, BTW. Will probably cost around $50 once the cost of packing is included.
