Well, if my Street Glide still had the factory suspension, you might be right. Although, I would call the stock front suspension on a SG a '77 Coupe de Ville, the rear air shocks are more akin to a 1945 *****'s Jeep.

Firm would be the word all right. Those Progressive monotubes still have to allow the front fork to travel in order to absorb the impact of a pothole, or the G force in a hard sweeper. When you installed those cartridges and lowered the forks 2 inches, you had to put in 2 topping springs and no preload spacer, right? That tells me that there isn't a whole lot of room for the fork to travel. If you only have an inch or so of travel left in your front suspension (because you lowered it 2 inches), something's got to give. You're either going to bottom out, or you're going to have one hell of a harsh ride. I'd put my money on the harsh ride. All you have to do is use some common sense and look at some of the pictures here of SGs lowered 2 inches in the front...the bottom triple tree is practically touching the front fender without the weight of a person on the bike. Do you honestly think that this setup is conducive to a comfortable ride on a touring bike?

No argument here. Stock suspensions on Harleys are embarrassing.

No teeth rattling huh? I bet you'd jar a filling loose on a good pothole. A skinny 21 inch front tire on a SG + minimal suspension travel in the front, is going to equal a very unpleasant ride. The bike still has to have somewhere to go when you hit that pothole. I'm saying that an inch of so of suspension travel probably isn't going to be enough to absorb that hit (compression or reboundwise), at least not comfortably...regardless of Progressive's cutting edge technology. Sorry, I'm just not buying it.

Let's just be honest here...you dropped the front suspension on your bike 2 inches primarily for a "look," right? You didn't do it to make the bike handle better, or for a more comfortable ride.

Just curious, what kind of rear shocks are you rockin' on your SG?

 

I lowered my bike for three reasons. 1) To offset the height of the 21" front wheel, 2) to lower the front end down so I was closer to flat footing it and 3) you're damn right "the look".
I took my time and did as much research as I could before lowering it though. I didn't want any regrets and I honestly have none. The OP was asking for opinions on lowering so I offered mine. I've had all kinds of lowered vehicles, some good, some bad and some horrendous; I didn't want to make a mistake on my new(ish) bike. I've got some riding buddies with lowered front ends (without monotubes) and they are less than happy with the ride quality, they've ridden mine and are impressed.

Rear shocks are still stock, lookin to change that soon. The feeling of the front vs the rear right now is significant to say the least. Also, I need to lower the rear 1" to match the front.

 

The 140 front tire on my 21" wheel is about 1/4" skinnier than the stock tire.

And i'm dropped 2" so the bike sits level. rides like a champ.

also, when i hit the ditch at 60-ish, the monotubes did a great job. front fender never hit the lower fascia and the forks arent damaged.

 

The stock front tire on a Street Glide is a 130/70-18. You sure your front tire is a 140?

You were involved in a crash at 60mph on your lowered bike? First off, I'm glad that you're still with us.

How did that happen? Did you fail to negotiate a turn? Do you think that your suspension (or lack thereof) might have been a contributing factor to your crash?
