The rumor of a new frame ?
#22
Sure, they go thru a lot of maintenance checks but still - great argument for aluminum frames.
:-) I'll probably still prefer steel motorcycle frames though

You would think an aluminum frame would save weight but often since they need to make the aluminum strong enough for a motorcycle, it winds up weighing just about as much as the steel frame. Ask Honda about that when they went to an aluminum frame on the 2001 Goldwing 1800. Didn't really lose any weight when compared to the prior steel frame Goldwing 1500. And to this day, they are still having problems with the aluminum frame cracking.

Where did you get this from? It might be an issue with the wrong alloy of aluminum but I don't see it.

The frame members on a heavy touring bike, if made of aluminum would have to be at least twice the diameter. Ever seen an aluminum bicycle frame compared to a steel one, Such as the Cannonade bikes of the late 80s and 90s? . So, to avoid the huge weird looking frames you get the expensive exotics of carbon fiber and titanium.

This is why I bought a first year M8 and didn't wait for next year. Last year there was talk about the new frame in 2018. Just like the victorys and Indians, same frame across the board. Harley does not do this for improvement. it is a cost savings for them. I am glad I didn't wait, regardless what BS they try and use to sell it.

It's probably not a good analogy. You are comparing aluminum to chromalloy as far as sizing on tubes for a bicycle. HD frames are likely 1018 steel or maybe a little higher carbon content. Also there are advantages to using thinner big diameter tubes when looking at over all strength.. That can have disadvantages when dealing with a frame that has high weight. Tunes can crush.
I'm not a fan of aluminum frames on HDs tho.. The whole bike needs to go on a diet. But then.. It wouldn't be a Harley..
An 03 FLHR SM lists at 723 lbs dry. Add say 30 lbs for fluids so say it's 753. The SM lists the running weight for a 17 M8 FLHR at 826.. Do you think HD is going to drop that bike 73 lbs going to an aluminum frame ??

H-D did report that they are working on a "unified frame" with no detail on what models/families involved.
Since they also said the Lowrider S and V rod are out for 18 maybe they are the going to have a unified frame and maybe engine. Maybe all but the touring. No one knows. I will just wait for the 18 models. H-D has also stated that there will be 10 new models each year for five years.
To many changes for me. Going through my different bikes now I need to remember how to activate the hazards, cruise control location and where even to start the bike. The 16 RG CVO and the 16.5 Lowrider S are started and turned off different than other H-Ds. It may be time for me to give up.

Cannondale bikes (I have two) are oversized so they can make the frame thinner and reduce the weight even more and increases stiffness. I also have a Raleigh tri light (also aluminum) that has normal size frame tubes.

I owned a Goldwing 1500. that's damn near a 950 lb bike. the 1800's were in the 780 pound range. I am not sure where you got that information from about the weight, but its a VERY big difference in weight. also the frame cracking was only for the 2001 through 2002 and it was only like 1 or 2% of the models made that year. of course its a VERY bad situation on the frame cracking, but that's seriously overstated.
