Centre Hub Steered bike
bp:
I seem to remember reading about the ELF GP bikes, that their only real failing was the front swinging arm, which had to be wide to achieve the minimum steering lock, only had to kiss the tarmac and the rider was on his ear. A lot less forgiving than the "normal" set up.
My final year project at college was titled "Motorcycle Suspension". It detailed a Hossack/Fior type set up. Just afterwards BMW introduced a very similar set up! Never mind.....
Best of luck
cheers

I didn't build a Centre Hub bike because I think forks are wrong, I did it out of curiosity, Forks have inherent but have had well over 50 years of development by every motorcycle manufacturer on the planet and millions spent on solving these problems, Centre Hub systems also have problems however they have had far less time and money spent developing them, I wanted to see for myself what it was all about and thought the best way was to build one, I now know a lot more about what is required and the failings of both, I've yet to come to a conclusion as to which is better, there are good and bad point in both systems, my next project may well go a different route perhaps a Hossack type setup but wit my take on it, and probably a V4 engine.

Telescopic forks are wrong.
If you put 10x engineers in a room to invent the motorcycle, then the one that suggest's telescopic forks to hold the front wheel would first be ridiculed, then thrown out the window.
This bike grabbed my attention. Very out of the box thinking yet still retaining a strong link with the UJM.

Incidentally. When asked, most riders with an eye on the future path of motorcycles, actually specify most of what is common on todays popular scooters !

My view on the above is it depends on what the bike is intended to be used for, modern forked bikes are remarkably good at most things, and its what we are used to, and some of its so called weird characteristics are useful, but the forks are only part of it, we could get into wheel paths, stable rake and trail under breaking etc etc etc, it could turn into and endless debate, but at present in every form of motorbike racing that I know of forks are it, that's not to say it wont change in the future, it probably depends more on marketing than engineering, I find most bikers are pretty conservative and prefer what they know, if a major manufacturer started racing an FFE bike and won with it things could change fast, but with Control tyres prevalent in most racing its unlikely because Tele forked bikes tyres aren't ideally suited to FFE bikes because they don't work the tyre as hard and consequently require softer tyres.
As for the motomorphic, Not for me, having said that I know some people hate my bike, but I didn't build it for them I built it for me for the reasons already stated.
A an aside I've also been playing with Steer by wire, and it shows some promise, this uses haptic feedback and totally eliminates bump steer etc etc, now this really is a can of worms in the making.

Excellent fabrication work.
Were you able to get road legal usage of a prototype, without emmision controls installed?

Apparently, he just wheeled it out of the shed, lit the fires & kicked the tyres & all was beautifully awesome. Where have we heard all of that before . . .
Time rich & £cash rich. Knows all about the info that's bandied about on t'internets, but knows now't about the real garage inventors.
He's never heard of 'Andy Stevens', Shig, Stu or even Sid & myself, yet he worships the false icon of some con artist called Hossack.
Does the bike handle? No, I don't think it does.
