I did do search and have found lots of info. But am still a little unsure.. I am about 155 pound and i ride 2007 gs500f. I hate the softness of the front end. I do not want anything to expensive because i am on a tight budget. I do sometimes ride with my girlfriend on the back and i read to take that into consideration when choosing a sprind.

What do you all suggest.

how does the rear shock feel? you may want to change that for 2up riding as far as the front goes progressive springs cost $60 from ebay or other places

The rear seems fine from what i can tell. The front is just sloppy. I was under the impression that there was different types of progressive springs....
Thanks

nope just one straight rate springs come in different sizes for different weight applications. progressive are all the same for the gs and they are progressive as opposed the the straight rate read this for more info copied from the wiki

Progressive Springs

These springs increase their rate as they deflect. For example, applying 20 kg of mass over the front forks may cause 20 mm of deflection while 40 kg will only cause 35 mm. Stock springs are linear, so every 20 kg will cause 20 mm of deflection.

They can be ordered directly from a Progressive Springs dealer. The Progressive part no. is 111128.

The cheapest supplier is Motorcycle Accessory Warehouse, where they are $49.95 plus shipping. The part no. is 02517.

Another good manufacturer of progressive springs is Hagon Shocks. They cost Ã,£61 including both delivery and fork oil.
Sonic Springs

Of the two companies that offer straight rate springs (RaceTech and Sonic), Sonic Springs are the cheaper of the duo. Sonic Springs cost roughly $80 plus shipping and are straight rate springs. http://gstwins.com/gsboard/index.php?topic=24872.0
Racetech Springs

The second, and slightly more expensive, manufacturer of straight rate springs for the GS is RaceTech. Retail price is ~$110 plus shipping, which comes out to ~$125 in the continental US.

When my 89 GS was 95% stock I had progressives with 15w fork oil and 97 Katana 750 rear shock.I am 200# and I rode with a passenger once.I had no problems.I live in an area with bad roads and the progressives seem to work well.Straight rate springs for your weight will compress a lot more with 2 people than progressives.

155 lbs isn't heavy enough to overpower the front springs ... especially without clip on's that actually put a lot of your body over the front wheel ... you sure you dont have something bad in there ... like no fluid in it maybe. Like they forgot at the factory  I dunno, 155 seems light to me.
Cool.
Buddha.

I am 225# and the Progressive Springs have been a Godsend for me in helping with the nosedive while braking. Also responds better in turns. I got mine form MAW and put em in myself using the wiki instructions. Quick, affordable upgrade in my opinion.

yeah i have checked the fluid levels and so did the mechanic at my 600 mile tune up.
