Just wondering if there's a supplier in the UK? Or is Sonic Springs my best bet?, just wanted to avoid expensive postage cost.

i live in the uk and have been looking aswell

Hagon do progressive springs for the GS, i was lucky enough to buy some forks which had progressive springs fitted, waiting to go onto my project bike. I am in the UK as well but lucky enough to go to the states at least once a year. so i pick up a lot of parts then as its a lot cheaper than here in the UK.

heres the link to the hagons. not a crazy price to be honest.

Hi guys, do these progressive springs make a big difference go handling?? I've never upgraded before so I'm a novice when it comes to springs haha

Do you think they'd fit a 2002?

If they are for a gs500 then I think they should fit any year?... but someone say otherwise if not please!

All years are the same.

Springs and fresh oil make a pretty big difference if you weigh over 170 lbs

I weigh 154 lbs.. is it not worth doing then?

Still will improve the handling/ride under spirited riding conditions! .. even lightweight folk can bottom out the suspension with heavy braking or sharp bumps/potholes....

The stock springs are pretty woeful!..

Put a heavy fork brace with the spring upgrade. ..  and eventually an r6 rear shock and you'll love it!

If your going to keep your bike for awhile these mods are advisable.

Does anyone know what the stock spring rate is? I was always under the impression that the GS suspension was designed for a 150 lb rider. I think an R6 shock and progressives would be too stiff. Seems like everyone who upgrades the suspension is 170 lbs or more.

The stock fork springs are less then 0.60kg/mm, which is good for someone in the 70-100lb range. Not too many people on here meet that criteria.
I don't know what Progressive offers for the GS500, but Sonic Springs come in a range of rates so the virtually anyone can get exactly what they need.
Other companies like Race-Tech and Traxxion also offer springs in a variety of rates.
