Bonneville America Forums Forums Technical Forums Accessories I Love my bike but...........

The stock suspension sucks!
It is especially noticeable when I get on my Harley immediately after getting off the Speedy, its smooth as silk comparatively, don't feel like I am getting beaten up! Please help me upgrade! Also a better seat wouldn't hurt either..............

A lot of folks do progressives up front and back. Look at Fast Eddy's site.
In terms of the seat, I have to recommend the Corbin.

Do the Suspension upgrades really work, I hate to spend the money and still be unhappy!

progresssive front springs and 440 rears

Thanks yall, sounds good, I need to upgrade the seat and suspension soon. Yeah I know they aren't Harley's I had an America before the Speedy, bought it back in 2003, I have only had the Harley for 16 months, love them both!

Progressive suspension and corbin seat. Made a 630 mile day an easychair cruise.

Any opinions on the progressive heavy duty 412's. I'm 6'5" / 250 lbs and the 440's are not recommended since they do not come in heavy duty.

That's what I was wondering too, I'm the same size as Ijpm. I had to put in heavier fork oil when I changed to progressive fork suspension. I've been putting off doing the rear suspension because I'm just not sure what the best choice is.

I really like mine. I was a bit heavier when I bought them, now I weigh 30 pounds less, and they still suit me fine. They ride a little bit stiff solo, but 2-up they are super smooth. No more bottoming out, and handling is great all the time. I would have gotten 440's if they were available in HD, or maybe 12" or 11.5" 412 if they came in HD.

I too was really concerned after riding my first lengthy few hundred k's and new straight away I needed help. First thing I did was get on here and ask questions and was told much the same thing, change to progressive suspension both front and back and look at buying a descent seat.

So I bought a corbin saddle with backrest and Hagon nitros rear and hagon progressives springs for the front.

Yes it did take a little while to get my corbin to feel right and now I just do not get a saw backside ever. The hagon nitros required me to get the springs rated to my weight, which I did and now I have got it sussed.

Over your way I hear a lot of you blokes are buying the progressives and provided you can get the springs rated to your body weight and also feel comfortable you can adjust the pre-load for more or less weight and not require different springs, then you cannot go past having a chat to Fast Eddy. He is not only as honest as the day is long and a top bloke to boot, but he'll make sure your purchase is one you are absolutely happy with. I've got no doubt whatsoever about that. Good luck

I have the progressive 412 HD, and to me they're only slightly better than stock. But I'm a big boy, and opposite of Dave, I've gained 30 lbs since I bought them. They may be fine for you. If I had it to do over again I would have spent the extra cash for the 418's or 440's.

I love my 440's and progressive front. Still working on a seat though.

If you're still looking for a seat, I have a Triumph touring seat available. Add is in the classifieds section.

Progressive 440s & front springs: great for many years. As for a seat, my home-made backrest is all I needed for myself.
