As a work of art it is beautiful. I applaude two blokes in a shed showing off their metalworking skills. As a motorcycle it leaves a lot to be desired.
Mr Suspension Smith, see my original post, is now experimenting with lateral suspension. Well as you do!
Can't quite understand the 'lateral suspension' idea. I always thought that you wanted the front to be rigid as far as lateral movement went (flexing of forks, etc) and manufactures have spent a lot of time/money on making steering heads stiffer and USD forks to stop flexing (although some USD forks are more for fashion). This idea gives sideways movement to the bottom 'fork' clamps, so how does this help handling?
That was the case when I was a boy, the stiffer the better. But my understanding is that the world's is a different place now. It seems that every man and his dog gets their elbow down now, and of course when at a 55 degree lean angle suspension that can only move vertically with the chassis (and is loaded up due to the turning force) is fairly useless when a vertical bump comes along. That leaves you with only the tyre and chassis flex giving you any "suspension". The old KR gp team were the first to tell everyone they'd got swing arms which they could tune for the amount of flex they wanted by changing inserts, and although they claimed it as a first I doubt they thought of it first. Those front engine mounts which drop off the main frame spar and used to go to the cylinder head, and now seem to be getting different lengths every season for no apparent reason...that's chasing the same thing - lateral flex or twist around the headstock. Longer means more flex, shorter means less flex. Not as adjustable as what we see here of course! I hope it's never available on any bike I can buy, I can barely keep my tyre pressure right - I shudder when thinking of what a mess I would make adjusting my lateral shock damping!
Something like what @Abel said. If you can be bothered going through the tedious process to join that forum then you can get all the sordid details. Then there is Ducati's new thingamajiggy. http://www.therideadvice.com/ducatis-innovative-sideways-suspension-solution/ I think they are all onto this now. My poor R4 project won't have lateral suspension. It will just be a dinosaur just like me.
There was a good story by Colin Edwards about this when Bayliss & Edwards were at it in WSBK. Edwards just couldn't get the Honda to go around corners and complained that the Ducati might be wallowing like a whale but it had what it needed to get the job done. Apparently, Honda went to the local store, bought a Ducati, tested it to death, and concluded that the Honda was immensely stiffer. Whereupon they banged out a more pliable version and Edwards was on a winner. Who'd have thunk it?
Suspension Smith wins a brand new Kawasaki 300 Ninja for winning the Formula Extreme D grade series. Gotta be doing something right. If you missed the opening post in this thread I am referring to his Hossack style front end.
Having such designs is one thing, getting them to market is another. Apart from manufacturing costs, the auto manufacturers don't want to deal with individuals and IP licencing, so you have be employed by one of them and then hope they like your idea enough to test it. For now, the traditional forks are lighter, cheaper, simpler. For now... I'm working on it.
