What is the top speed of a 400 or a 426 with stock gearing or the fastest you have had yours up to and what gearring you had :thumbsup:

I can assure you that no matter what ALOT of people will try to feed you...a STOCK YZ400/426/450 will not do a penny over 80 MPH...most are in the 74-76 MPH range...go up a tooth or two in the front and its a whole different story.

Haha it seems like this post comes up at least once a week. The mods should make it a sticky item in this forum and say a stock geared YZ426 won't go faster than 80mph.....if yours is faster, you lie :thumbsup:

Then that would explain your top speed...the WR has a wider gear box and 5th gear is taller...thus explaining your higher top speed! A stock WR might do 85...but probably not much more.
