Saw it in the Motorcycle Trader. Very awesome

There was something different about the motor. What was it?

powered by a 1-liter inline-four with staggered cylinder blocks and stacked, contrarotating cranks, the whole thing positioned lengthways in a carbon-fiber chassis equipped with radical front and rear suspension systems.
Inline-four is certainly different.

That was it. They said in the motorcycle trader that this set up made it a totally different bike to ride. Sounds great too. Check out the Videos on the homepage WRT gave the link too

too much cabling and pipes exposed for me. i reckon the next development of bikes should be to be hiding all of that - bit like underseat exhausts etc

Why have an in line engine and then turn the drive 90 degrees for chain drive? Makes little sense.

Width for one.
According to an article on the website, it also removes the gyroscopic forces that inhibit leaning over, instead helping to prevent wheelies and stoppies.

It's a staggered V4.

But you trade that off for length and power losses turning the drive through 90 degrees. I have some doubts thats all, (I did read the article ya know)

Well it's staggering thats for sure...

It's very nice and if the engineering is half as nice as the marketting we are looking at the next world champ BUT - I have serious doubts about the engine config.

Hey - the sound on the video alone justifies building it.... Seriously horn!
