I posted this over on the ISOK site to alert others with GL-1800 about the need to keep a close eye on your frame. I know that I do and if you are one of those who beleive that all the hoopla about Frame Failures is just an Internet thing please skip this message it isn't for you.
Most GL-1800 riders have heard about the Frame Recall of '02 & '03's
for corrective welding of the Shock/Centerstand Crossover joint that
has been reported in quite a few failures.
The newest of 3 known Frame Failure points has shown up in the Rear
Triangle just behind the one addressed by the SB-14 Recall. At this
point Honda has at least 15 reported failures in the new location
but has yet to identify the Failure Mode or any specific cause. It
has been reported that the Rear Triangle Frame Failures are showing
up throughout the '01->'04's with a mix of Trailer Hitch & No
Trailer Hitch. The one item missing has been a response from Honda
about any possable Trike/Sidecar involvement.
That has changed with a report on the GWRRA board about a Trike
Frame Failure that caused an Output Shaft Bearing Failure due to the
flexing of the driveshaft caused by the deformed frame.
I have been in contact with Hank (Henry) about the Frame Failure and
he told me that it was NOT covered by either Honda or the Trike
Maker - The Trike Shop. The Trike Shop and Hank both agree that the
problem is with the Honda Frame and not the Trike. The end result so
far is that Hank has had to pay for all repair out of his pocket for
both the Drive Output parts and having the Frame Re-Welded in a
questionable location along some very thin tubing. So far for Non-Trike/Sidecar frame failures Honda has been replacing the broken frames most likely due to the need to analize the failure mode or because the tubing is too light to properly weld. We don't know the reason and Honda isn't talkin'.
The concern for Hack Pilots is that the area that is breaking is the
same area that most of us rely on for the Rear Mounts to anchor to.
I for one am keeping an eye on my frame in the suspect area & would
caution others to do the same when ever other maintence requires you
to be around the Rear Triangle.
The location to check isn't easy to see and is probably overlooked
by most riders due to the difficulty to access it with the Sidecar
Mounts in the way.
If you want to see where to look checkout Fred's site and make note
of the location and method needed to see it.
Chances are very few will ever find a crack or broken frame member
there but if even one accident is prevented it is worth spending a
little time to make sure your's isn't one of them.
Note that Honda has taken a stand aginst working with Trike &
Sidecar owners when any of the known Frame Failure locations is
found to be Deffective so finding a crack before it seperates may
help an owner get a proper repair without having to buy a new frame
for $2,500 plus the hassle of replacing it.

Can you tell me if the frames are made from steel or aluminum?

They are Aluminum and even the Aircraft guys wont weld it due to the likely failures at welded joints. Of course the Aircraft industry doesn't weld if it can be avoided at all due to problems with welding Aluminum in general.
Take a look at Fred's site where he shows a Yamaha 2 piece frame made of the same stuff. It isn't welded and is bolted together per Aircraft standards.
