@bubbleboy80 the 450 motor isnt as reliable as the 250, it would pretty much blow up on the highway, and thats coming from Yamaha's mouth....but hopefully tech will advance, ill be first in line for the wr450x!!
-
I love Yamaha, but I really wish they'd just make a 450 or 500 enduro/sm, or legalize the WR450F.
-
top speed?

Are they proper certified dyno tuning thongs?
-

Very impressive hp numbers, This is going to be the future for motorcycles now, (EFI) Over here in oz i went to my local store to buy a new weed wacker and the brand is called sthil and its a 4 stroke that has no oilsump or resivoir, it runs on a mixture of 2 stroke oil and gasoline to lubricate all of the valves piston and bearings, but the oil mixture is so thin it doesnt produce any smoke like a 2 stroke
The reason why they do this is to reduce weight. this could be all motorcycles future
-
@JaysBestClips because these hp numbers are based on actual read wheel hp not at the crank. that motor is probobly putting out about 45hp or so at the crank.

@JaysBestClips Can't beat a smoker for brute force, eh Jason? I want a 500 like yours :)
you should now invest in a MPfab turbo and do this over
