Cool, I hope it makes it to production.

"Riding a bike remains very dangerous: there’s lots of power and only a small contact patch with the road. On a traditional bike, a loss of grip on either wheel usually produces a crash."

These are exactly the people I want to stay on the couch. Go get a video game about motorcycles. Please dont ride.

Wow, that is incredible thinking out of the box. There's a lot of potential in a new redesign of basic motorcycling if this concept can be proven to actually work better than the status quo.

Reminds me of another oddity, although for a different purpose. Remember the 6-wheel Tyrrell in F1 racing? Sort of successful, sort of not.

I like it. I would be very interested in hearing about how it handles.

I always wonder if there are motorcycle ideas where Erik says "Huh, never thought of that."

50% more contact patch might be nice.

Still does not help alot if is there is oil/ice/diesel on the road.

All 3 wheels will slide.

Looks like the weak link is the steering linkage. Looks like it'd get sloppy before too long. Other than that, I want a go at it.

I'd like to see a version with no chain but all 3 wheels driven by a hydraulic drive system.
Set of knobbies, go anywhere.

That was the one thing about the Bimota Tesi/Vyrus design I didn't like. I figure it wouldn't take long for some slop to develop in all of those steering linkages and the bike would become a handful to control. Either that, or there would be a lot of expensive maintenance to keep them within spec.

I always thought James Parker's RADD design made a lot more sense. I had the opportunity to ride the Yamaha GTS1000 and it really was a joy to ride. Too bad it was so "different looking" and it didn't sell. I guess the BMW designs were more appealing in that they didn't look THAT different from the norm.

Nothing like pumping OHC v-twin power through a bicycle chain and sprockets. May need a rethink there.......

I don't think the steering linkage issue would be that big of an issue. The service interval of the shock would have to be longer than typical forks and wouldn't require the disassembly of the entire front end to service.

All of the linkage is open and accessable. You'd only need to make sure the fasteners are tight.

There wouldn't be the deterioration of fluid, leaking seals, stiction issues caused by problems with damage to the inner fork tube, etc.

Also, the front suspension could be more tunable for less cost. If you are replicating a basic rear shock design for the front, you could have high and low speed damping and compression settings for a lot less money. In addition, you wouldn't have as many problems syncing two different fork legs with more setting options.

I think there are more beneficial options to the set up than negatives.

I'd rather see a belt drive vs. the chain.

Wouldn't it now go backwards with the engine flipped around like that? It mentions the belt to change the direction of rotation, but belts don't do that...

Overall it looks similar to an idea I had, except I just had the two front wheels. Super short wheelbase that would use an active feedback control system (ie "fly by wire") to replace the stability lost.

I also don't see how you could counter steer with that 3 wheeled design.

Actually, what the artice mentions about the rear, trailing wheel echoes what my GoldWing riding friend said when he installed a mono-wheel trailer on his Wing a few years back. Hmmmm...
