I love it! Tons of innovation I think they're even going to teach riders how to ride standing up with that under seat header pipe. I'd be really surprised if ass heat isn't an issue.

Funny thing is when BMW came out with the 450X and centric CS sprocket i thought to myself... Been done before and discarded as not an advantage. Yamaha had a design like that and those who rode it said the the lack of suspension loading under acceleration was a bad thing not good. On paper it makes sense, in real world use it did not pan out. It works but there are trade-offs.

Yeah, nobody's ever had any success with eliminating chain torque on the rear suspension. ATK even had to finally give up their design. It allows the suspension to work much better, but effects the attitude and reaction of the bike.

You can see how they made some brackets to move the motor forward, off the swingarm pivot.

Is that something they've done just for their own team race bikes, or are they now doing it on the bikes they sell to customers too?

exhaust pipe is nuts

looks like the pm tuning exhaust for the vespa et4 125cc scooter:

[Troy F Collins]

The cylinder is pointed backwards...closer to the center of mass...and also the roll center....same with the fuel....its moved back too

And the airbox gets denser air charge near the steering head....as well the exhaust is straight out.....

in the 80's it used to be Honda that made all the big moves.....


but starting with the 4 stroke era in modern motocross..its been Yamaha...except they have followed a very evolutionary concept...TILL NOW

This is real big stuff.........

Looks like the cams will have to be removed to get at the shims - from the pics.

I think YZF's were always like that......

yep, as is the new 250F husky motor. the nice thing about the husky motor is the cams are gear driven making them EZ to remove.

Thanks Norman,
I am always spouting that one off among the MX faithful,,,,,before Jacky Martens, I believe it was Jeff Smith on the BSA B50 (Cheny or CCM I believe), there was long gap

That cylinder is the first thing I noticed as odd looking, with the typical frame lines going forward along with seat/tank that cylinder is actually slanted backwards. Maybe thats more for the exit of the pipe and straight air intake now instead of weight distribution. And notice how flat the bike is: Husky all the way.
Also cant really see the air intake size ect. but does'nt the front of the bike really take on most of the mud, blood and beer during a race. I see possible trouble there. Call the plumber we have a clog.
anyway, good job yami.

Sounds like an awesome bike!

It would be quite interesting to get a ride report if any of you ever ride one.
