I'm guessing you mean the front brake fluid reservoir?
Regardless the front reservoir is typically $25 used on ebay, and the rear is almost always cheaper (around $10)...
I'd still check ebay for cheaper though, these parts are usually plentiful on there, as they aren't typical damaged badly in a crash.

Someone please jump in if this is misinformation (of jump in to reaffirm), but I believe any year GS500 should work for the front reservoir.

There are quite a few there.
I have always received good parts from Pinwall Cycles

Any year will work - so go for the newest you can as older ones could be nearing the end of their life before a rebuild is needed.

The newest OEM has a glass window instead of plastic. My 2006 did the same thing, I just got the new revision to preven future issues.

The pee cup style reservoirs from other bikes can be used to replace the OEM Suzuki one. I know slipperymongoose used a street triple one on his GS.

I've been seeing more and more people putting sweatband covers over those cup-style ones. Something about keeping the sunlight off the oil or something.

Basically any non abs handlebar type reservoirs you can use cause they simply clamp to your handlebars. For me when my brake was squishy and the rebuild kit didn't work I managed to score myself as twisted said a speed triple one. If you go down this path make sure you get one where the fitting is the same orientation as OEM. You will just need to splice up the two wires for your brakelight and and you should be good to go. And you will have to be very careful on your braking cause most likely the new master will be for a twin disc setup and will be more powerful so locking your front will be easier just adjust your technique to suit. I would suggest a sv650 one and while your at it get a clutch perch and you can buy aftermarket adjustable levers. As for the socks you see on these 'pee cup' reservoirs it's to protect the hygroscopic thing in the brake fluid itself so it doesn't go bad quickly.

The covers really started with drifters who put them around power steering and brake fluid reservoirs. Power steering fluid boils with hard use (eg drifting or general track driving) and the brake fluid reservoir lids on cars aren't as airtight as bikes so in both instances there tend to be leaks. Japanese brands like HKS and Cusco make "socks" specifically for this purpose.

Now you have no idea if your running low or what condition your fluid is in  :cookoo:

It will require more work to take the cap off and check every so often, but can't beat the price if that's the factor  :thumb:

just change the fluid once a year.

I like the idea  :thumb:
