Fork Springs Questions
I have been reading about different suspension enhancements on the board.
I am thinking about replacing the fork springs on my bike. I have replaced the shocks and think this will help beef up the suspension. When I got the bike it had 20K miles on it. The shocks are night and day difference (progressive 412)
My questions is what does lowering the front end do? Is it purely cosmetic? What are the pros and cons of going with the progrssive drop in springs that I have seen other members install. I like the ease part of this mod but was unsure what the lowering part would do.
My other choice is Race Tech .95 springs and gold valve emulators.
I would appreciate any feedback

I do not necessarily want to lower the bike. I think I want to keep it the same height in fact. Just not sure if the Progressive drop ins can keep it at the standard length.

I had a XL1200R '04 and fitted progressive springs up front without the lowereing spring,reason why.....to stop dipping under hard braking and to beef up the front.The bike handled better and made enough difference to the feel of the bike it inspired more confident riding,actually thinking of doing the same to my SB...can only recommend it but maybe you might want to try changeing to a heavier fork oil first and see if you like that before buying progressive springs???

I installed the Race Tech gold valve cartridge emulators under my stock springs over a year ago and the difference was night and day. One of the best mods I've done. I did have to take the dampening rods to a machine shop to drill the holes called for since the rods are round, it wasn't something I could do at home.

+1 on the heavier weight fork oil that would bet the cheapest way to improve dipping if that is an issue. If stability is an issue a lowering kit does make it better....just did mine and i love the feel.

I can only speak for the standard length Progressive springs which are a good improvement over stock.They work as advertised they provide a smoother ride over sharp bumps while reducing dive under braking. I also switched to Bel Ray 15wt oil but will likely try 20wt in the future.Now,I have a Suzuki SV650 with Race Tech straight rate springs matched to my weight and riding style 15wt oil and cartridge emulators.This is supposedly the hot set up for dampening rod forks but it is approximately 4 times the cost and I can't honestly say it's 4 times better.Depending on much you like taking things apart or how much $ you have you can just try the thicker fork oil first and go from there, or try the Progressive standard length springs and the fork oil and be done with it.Or if money is no object go the Race Tech route.

I want new springs up front too, but I don't want to go through the hassle of changing my oil again, as I just did it a few hundred miles ago. Do I have any options, or do all require me to re-change oil? I know the progressive drop in kit won't require me to change oil, but I'd really like to get race tech springs, or maybe works performance even...
Edit: Oh yeah, forgot to mention. Changing to a heavier fork oil made a huge difference. I am using SE fork oil, and it really stiffened up the front a lot, and there's much less dipping. Give that a try as well. I still want to change my springs though.

If you just changed your oil you could do the Progressive standard length drop in kit fairly easily.If you pull the springs out slowly enough you could probably do it without loosing too much oil.Come to think of it you could also put in Race Tech straight rate springs but probably not the emulators as I've heard you have to drill the dampening rods or something.
