GL1500 rear shock questions / ideas

Post by blibecap »



I have read a lot about the concern of poor read suspension on the gl1500. I have looked at Progressive suspension stuff and it's a little rich for me. I have a low milage 1998 gl1500 see and will be doing some riding 2 up so about 450-500 lbs payload (each 225) . I was wondering if there are any less expensive good options. Has anyone ever tried replacing the air shock (right side) with a sprung shock like the other (left) side? Any success stories using stock shocks from other motorcycles like HD or BMW.

I was looking into this also few years ago, found out the combo (R) air shock & (L) spring shock is the best overall suspension.
The Goldwings are comparable to Caddy's & Lincoln's plush ride attributes. They're not really 'trucks' but you couldn't pass that past me considering how I use mine in hauling seemingly anything.

If you're dead set then you might get lucky in a pair of adjustable shocks from a (for say) Suzuki - Yamaha - Kawasaki (etc.) 1200cc bike.
Tho the upper/lower EYE sizes & travel lengths might be a problem.
HOPEFULLY someone will stop by and direct you to something that worked.

I've always wondered why someone couldn't take a farm (rake) spring and add that to the left swing-arm. It give a 20 - 50 lb boost.

Do a search on here for 1500 replacement shocks you will find a few threads that list exact Harley rear shock swaps.

I know for a fact that 1997 Harley Electra Glide Classic FLHTC have 13.5 inch rear shocks that fit.

I have seen many HD air shocks and always wondered but never researched if they would possibly fit. HD dealers just toss them when bad instead of rebuilding them. Rebuild kits with seals and o rings are still available from Progressive Suspension. I rebuilt my 416's a couple years ago and it is quite easy. At least I think so. Hardest part is getting to them and removing and re-installing them.

Hagons produced a single rear shock for me some years ago. It replaced the old spring shock and I serviced the air bladder.

Does it work? Well, it scares the whatsits out of people I ride with when I attack some bends as they're convinced it won't corner that well, so I guess it does :D

The downside is that it gives a firmer ride so, if you enjoy a "sofa soft" ride, this may not be for you.

Ciao a tutti dall' Italia.
Io ho un GL 1500 SE del 1992.
Ho provato a montare 2 ammortizzatori ad aria invece di quello a molla e quello ad aria. Dopo poco tempo gli ammortizzatori
non hanno più funzionato bene e sono ritornato al vecchio assetto cioè un ammortizzatore a molla ed uno ad aria.
Per quello ad aria, anche se molto costoso, ho montato quello originale Honda. Quello vecchio l'ho fatto revisionare ma con scarso successo. Consiglio di acquistare sempre gli originali. Buona serata

Hello everyone from Italy.
I have a 1992 GL 1500 SE.
I tried to fit 2 air shock absorbers instead of the spring one and the air one. After a short time the shock absorbers
they no longer worked well and I went back to the old setup, i.e. a spring shock absorber and an air shock absorber.
For the air one, although very expensive, I mounted the original Honda one. I had the old one serviced but with little success.
I recommend always buying the originals.
Good evening
Massimo

Hi Everyone,
I had a rear suspension failier taking the 08 1800 round the Nurburgring. When I sent the cusion to be rebuilt it was too far gone. So I ask around and got a Hyperpro all the way from the manufaturers (for a real good price) a couple of years ago adjustst as it should and still going strong. Even quite happly get on those sparklers and those **** strips are gone. Also got Marzzochi Stantions and cartrages. It really was worth the expence the bike handles so much better. Though I need a good Fork brace for and airbag model.
Take care and safe riding

I installed shorter 12.75" non-air shocks purchased from eBay which lowered my bike giving it a lighter feel due to the resultant lower center of gravity and I prefer the lower ride making it easier to mount and dismount. The shorter spring shock renders a rougher ride though compounded by the fact that they have less shock travel but it's a tradeoff for achieving a lower bike. Be advised that when lowering the bike, the main and side stands may need to be shortened to function as normal.

Try Monroe 785 airshocks. They are cheap and go on Corvettes? I've used them on a gl1200 with good results. You may have to rig up a stand alone system.

FWIW, I reached out to Hagon for some info. they told me they manufacture replacement shocks, which then has no air assist after install. They also have a L/H unit with preload, compression and rebound adjustment. the R/H would remain the stock air-assist shock. this solution is somewhere in the neighborhood of 500 bucks.

Sounds like a better option than getting some steel bars and making it a hardtail. :twisted:

A GL 1800 "suspension" is a completely different set up. About as close to what is oem on a 1500 as the older VW's torsion bar is to newer strut assemblies! 1800 has single hydraulic shock piston with a spring cushion. The adjustment actually makes the shock longer as the numbers go up by roughly a inch. Not much comparison to 1500 which is more like normal motorcycle suspension.
