I can hear the lawyers screaming from Japan all the way over here...

That looks bad A. I wonder why there going to 4 valves? Are they still gonna have 2 cams?

plastics look like RMZ's.....keen to se how these go

Wow exhaust has crazy loopdy loop

It's obviously a twin cam. The move to the 4 valve head is being made for a number of reasons, most of them likely related to performance. The triple intake port is extremely difficult to get big power from beyond a certain point.

The exhaust needs to be a certain length for good performance, thus the loop. The head was reversed to allow the intake port to be raised, not to shorten the pipe.

not one but we get 2 new front fenders, :crazy:

I will be buying one. thats wild!!!

The backwards exhaust will help for alot of the over heating problems that the 450's had. Thats the hole idea with the switch head. Also the carb will be geting colder air because the motor is not heating all the air as it goes by the motor.

Its a great idea, Im very intrested to see how this thing does.

rear facing exhaust = backward spinnging crankshaft .... moto gp style.....

What possible connection does the orientation of the head have to the direction the crank rotates?

You have 3 shafts there, geared together. The output spins forward, the mainshaft backward, and the crank forward.

I would not call this a spy photo but interesting never the less......just like all the other threads on the same thing.

It looks as if 2010 is a completely new design. I hope they work the kinks out first unlike Honda:smirk:

I wonder if the under-ass exhaust will heat up the seat at all :crazy:

This is great stuff to see. I'm glad to see some innovation coming out of Japan. Seems like the big japanese makers don't take very many risks anymore. This bike looks revolutionary.

I just hope its true.

If it's true...I hope it works.

I like the multi colour chain.:crazy:

Still got 2 wheels, a motor and a seat, looks like fun to me. Im still waiting for one with VSTOL capabilities. This forums going to be busy once the 2010s are out.
