A number have floated concepts. Lots of time looking into ROI. With 40k sould in over 4 years the numbers speak to why no further action has been taken by others.
Last one is a Honda concept. More city trike than anything else. They did have a concept I think 2 years ago that was a shot at a KTM X-bow so (4) wheels
Never in a million years would I think something like this
https://powersports.honda.com/…/honda%20side%20by%20side
would be a better seller than a slingshot type vehicle by Honda. I still can't believe there is a sustainable market for those. I have never seen one in action in real life. Seen my share of slingshots (before getting one) but never a side-by-side from Honda.
Matter of fact I would have to have a Honda exec actually show me a slideshow with hard sales figures to prove to me that their side-by-side has more sales potential then an autocycle. To me there is just way more urban-use sales potential then off-road customer base.
I mean the talon 1000r retails for the exact same price as a baseline sling for pete's sake. How does Honda think the slingshot design not sell???? That's crazy and I ain't buying it no really I would never buy a talon @ $21k.
Now you can make an argument that Honda along with Yamaha/others don't want to go into the autocycle business because of fear of cannibalizing their motorcycle sales, ok now that makes sense but to say that there isn't a name-brand demand for autocycles is silly. Campagna did it for 20 years until they were priced out of the market thanks to vanderhall and polaris.
The aftermarket industry would go bonkers for a Honda autocycle. I mean just look at what people do (with their money) nowadays with small cars like Hondas/VW/etc.
