Default Is progressive 11-1552 the way to go?

Is this the way to go? As we all know the stock springs compress nearly all the way just from the weight of the rider leaving no real suspension to speak of. I want to know if the progressive 11-1552 will make a large improvement or should I be looking at another brand?

You might get more responses if you posted the series number (411, 440, etc) and length of the shock you're referring to. I sure don't have Progressive part numbers memorized, nor the time or interest in researching it.

They will make a great improvement. This is the way my 2007 1200 C sits unladen. I used the accompanying spacers at their full 3" and 7w BelRay.

You'll get a wide range of replies! Shock threads are one of the most popular subjects and there are many ways of skinning that particular cat. Like cHarley I have no idea what those are, but don't be surprised if you find yourself buying more than one set of shocks before finding your personal nirvana. Starting again I would buy Hagon Nitro - British shocks for riding my Sporty on British roads!

11-1552 is the Heavy Duty Fork Spring set, 11-1527 is the standard set. I have the standard set in the picture above and at my 196 lbs. they are perfect..

My apologies fellas, they are fork springs only. The description says heavy duty progressive rate springs, I'm relatively happy with the rear shocks for now. I'm just looking for some testimonials from folks who have used these or other front fork spring brand.

Thank you for the picture 1200C. My bike has less than 4 inches of travel just sitting under its own weight, with my 180lbs added the front forks compress to around 3 inches.

I'm using the standard set as well, and it was a huge improvement over stock. No more bottoming out or diving down when I'm on the brakes. They also took a lot of the sharpness out of bumps, it's still not what I'd call a plush ride, but it's a hell of a lot nicer than stock. I just changed out the oil and replaced with the stock HD fork oil.

For the price, it's hard to beat the Progressive springs, but if you want high performance, or want to do touring or something, there are better, more expensive, springs out there.

I don't know that you ever got the answer you were looking for on this, but I'm looking at the 1552's as well coupled with ricor intiminators and 10w amsoil shock therapy oil. The HD springs have a rate of 45-78 lbs/in (as per Kyle in the PS tech dept), so the initial rate is suitable for a rider of about 170ish pounds. I'm at 220 and pending an absolute 'NO!' from some suspension gurus I've asked, I'll be trying these out soon(ish).

mind you the stock springs' initial rate is about 19.6lbs/in and the standard PS springs are 35-50lbs/in

These are one of the best mods you can make for your ride quality, and it's the most bang for the buck. They make for a huge improvement. You can find them on eBay for around $70.00 shipped.
