Motoczysz C1.

[rictus01]

I watched the discovery program "Birth of a Racer" recently, the aim was an all new, all american designed engine and bike for motogp, built from the ground up in 9 months in 2006.

Apparently the 990cc engine fell foul of the 800cc motogp change before it could be made competative so never came to much (hence why we didn't see it on the grid), but the new rule changes to the 1000cc limit might open the door for them once again?

found this (http://www.asphaltandrubber.com/racing/motoczysz-c1-motogp-2012/)

original and interesting design.

this is the 2008 spec

I watched it aswell :) it was pretty good, I noticed it was the same guy trying to do Iom tt with a electric bike, on the tt DVD

[rictus01]

yeah i believe they won the tt zero last year

[andrewsmith]

Yep

A version of this chassis won the TT zero with Rutter on board. They are expecting the 100mph lap this year.

Shame it fell flat with the 800 changes. Same as KTM's 990 monster (but that has funding like Aprilia's Cube project)

I remember reading about this in Motorcycle Racer, some of the ideas are lovely. Alan Cathcart who test rode it for the magazine said it was a lovely bike to ride. I've not seen the program must look it up. Thanks for the heads up it'll be on again soon no doubt.

[DJFridge]

That's a nice looking bike. I've just had to look up what a Z-line engine was, because I'd never heard of it.

It's such a neat layout, hard to believe they're the first to build one. Still, they always say the best ideas are the ones so simple that you can't understand why nobody else has thought of it.

Dunno if its that simple to have two contra-rotating cranks. Certainly well above my level of expertise... Having said that Lego Technic was pushing my boundries.
