Seriously!



In 1915 T. Roosevelt said, in a speech to the KofC, "There is no room in this country for hyphenated Americanism. When I refer to hyphenated Americans, I do not refer to naturalized Americans. Some of the very best Americans I have ever known were naturalized Americans, Americans born abroad. But a hyphenated American is not an American at all. "

There's another article linked within that one that talks about the engine, but I don't have time to read it right now. I wonder what the advantages/disadvantages are. I bet it smokes like no other after you let it set for a bit after running it, I know my dad's bwm does!

I hope they enjoy their 15 minutes because that is just stupid. Why would you want to raise the crank that high in the chassis making the gyroscopic forces work even harder against you?

Rob, does this idea make sense on any level other than publicity fodder?

Not really for motorcycles, but how about this engine?

The designer is clear in saying that strong visuals were a design parameter.
Look at it this way.
It's an upside down dry sump air cooled two valve inline 3 of large dimensions.
Things sort of flow from there.
This is clearly more art than function, and the designer's comments are in synch with that.
Everything about the engine means lower specific output capability as compared to current engine designs.
I'll bet it's a top heavy tipper waiting to happen.
Most of the densest materials and mass have been very centralized way up high, specifically the steel rotating parts.

I find that with a bag strapped to the back or with my GF on the back it seems to "fall" into the corners with less effort. Not saying that the whole project makes sense by any means, just my experience (which is very little especially compared to many here)

And for that very reason I raised up my entire bike front and back for track use.
I get more ground clearance and it is easier to tip in. (and a bit of improvement in swingarm angle, a real issue with 919s on a track)
A bit more effort to pick it back up, but the improved ease of tip in very noticeable.
A bit more lean angle is needed for any given speed at a certain radius.

In the case of the, shall we say, unusual engine driven bike package we've all been looking at, it's the degree to which they have gone with is, well, a bit out there.
Kinda neat though, as anyone doing their own engine always deserves some kudos.
The audio track sounded to me as though their fuel metering was way off.
I wonder if there was any linkage to the ancient Laverda 1000 triple of the 70s, the Jotta if I remember correctly.
Mr. Tharlson would know about that without having to check any reference material.
