Which would be faster?

[burgerj3]

I have a 02 400ex with a full FMF Pipe Stage 2 jetted and Stage 1 hotcam K&N airfilter with vented lid. Would a new 450R be faster or about the same? Just trying to get a feel of how fast the 450R is, cause no dealers have any available to drive in NJ.

the 450. the 400 will not compare to the 450! its just bad to the bone. it has some much power!

I have not ridden nor raced a 450r, but I have raced a couple stock yfz450s. I have not beat one yet. I am not that far behind, but my bike is not stock and theirs is. So, I would say a stock 450r is definately faster than your 400ex.
