HD's new leaning tricycle

For all 205 of you...

US Patent Office Filing by HD



Here’s something a bit different from the Motor Company, it’s a patent application from Harley Davidson for a leaning trike. It’s looks like a cross between the Can-Am Spyder and the Brudeli 625 but it is distinctively Harley with the big twin power plant in there.

Whether they are thinking of producing this or something similar, they probably wanted to get the paperwork in to make sure they were covered. Filed on either September 27, 2006 or April 5, 2007, I can’t figure out which dates apply, reading patent paperwork can be a bit confusing.
From the application:
The present invention relates to a suspension system for a three-wheeled vehicle. The suspension system permits the vehicle to lean while cornering, much like a motorcycle. This is accomplished via hydraulic actuators that force the bike into a leaning position while turning, and back to an upright position while tracking a straight line. A transverse beam is coupled to the hydraulic actuators and to spring dampers to allow the suspension to operate independently, even while the vehicle is cornering.

I hope they're going to pay Leonardo da Vinci's decendants a royalty for stealing one of his designs.

Won't sell.... It doesn't look like something designed in the 50s.

So after that shitlump of a motor runs a hydraulic pump, what's it got left over to drive the rear wheel, 3 horsepower?

Too little, too late

Hmm - Piaggio mp3 anyone? Just got back from Paris and these things are buzzing around all over the place.

A Harley that does the riding for you? Sounds like Miller Time to me...

I like it.

Where is the Jap version?

I need it cheaper and more reliable, ah! ... and faster.

With their aging demographics, I suppose HD wants to keep their older riders on their wheels.

The Piaggio is perfect for European cities and the short distances found there. Over here, a 3 wheeler needs to be a mile muncher too.. I like the leaning concept way better than the Can-Am rigid concept and execution.

The beauty is in the way they did it. If you look at the drawing of the trike leaned over it still has full suspension available to it. The Piaggo, to my understanding, does not (inside wheel is nearly bottomed).
