Now, for another twist...
My front end is 2" lower than a stock Wing. But, not by design.
I reached out to the manufacturer to ask if they altered the fork length, and was told "no". The 2" sag on my front end is just old age.
I need to bring the springs up to snuff, and then re-evaluate the trike ride to see if I actually need/want to install the rake kit. Right now, I'm riding this thing with a wonky suspension.
With that in mind, which springs would you recommend? Would it be detrimental to install the Progressive #11-1112 without the rake kit?
Or, is this one of those situations where I just need to bite the bullet, and install standard Progressive replacements, and then change to Progressive #11-1112 if/when I decide to install a rake kit?
The 11-1152 springs work better with their rate when used in a OEM GL-1500 front fork set which still has the steeper angle on the fork tubes. The 11-1122 springs with spacers have a softer progressive spring rate and it was through trial and error or experiment of others that showed the 11-1122 springs with the spacers of 1/2 or 3/4" length to ride better in a GL1500 trikes front forks that have been laid back at an increasing angle of 4 or 6 degrees.
It was totally by accident on my part I think, getting numbers mixed up, that I bought the 11-1112 springs and soon found almost impossible to get them and spacers into my fork tubes (I have a 6 degree kit
) so I left spacers out. I was thinking
I had the 1200 springs, I was pondering this when I double checked the numbers and found I had ordered the wrong springs, but I had them, saw they were minimally smaller in wind diameter, were same rate but 3/4" longer, and so I left them in my forks. Took a long ride later, they were great!
I still wanted to try the 11-1122s so I ordered a set, they were put in with spacers, they worked great too! It's very little difference between the two numbers, but I put the 11-1112s back in with no spacers, 7-1/2 weight fork oil (50/50 mix of 5 wgt and 10 wgt Belray
Think about fork tube angle, supporting weight, absorbing bumps. 6 degrees more lays fork tubes down from OEM approximate 27 degrees to more like 33 degrees, so a 2" bump verticle in the roadway compresses the spring further, which is why the softer front springs work well.
I think the 11-1122s would be maybe too soft in the front of a still stock GL1500 front end as there's more weight on a 1500's front wheel than on a 1200's. The 11-1152 that were in my forks before I added the 6 degree kit were great ride wise until I added the 6 degree kit
, then they were too harsh. It was like they went from soft 35 lb rate until they increased to thier 80 lbs rate, then harsh. I gave them to a guy with stock springs that were sagging, he loved them but his trike was not raked.
If it's going to be miles and maybe years
before the rake kit, I'd go with the 11-1152s until / if I put a rake kit on, then do bushings and seals too.
That's just me. The softer 11-1112s … or … 11-1122s with spacers … might work with air. I use NO air now in forks.
When at rest, my front forks are compressed maybe 1/4-1/2 inch from topped out so there is plenty room for compression, and a softer transition in rates from 40-70 lbs/in. of the 11-1112s
Once I looked up specs, I saw why the 11-1112s worked so well.
The rake kit will not make a softer ride, it will lighten or lessen effort required to steer however. If I were keeping it stock, with no rake kit, I'd go with the 11-1152 springs and experiment with / adjust fork oil.
If you make the mistake of trying a friends trike with rake, you'll go for a rake kit.
