What are the approximate top speeds of each (stock) ?

Thanks, Scotty

 

Everything from tire pressures, wind, and rider weight plays a big part of this.

But in the average situation they almost always run in the same range of spped.
A 300EX will run mid to upper 50s and a 400EX will run mid to upper 60s...both box stock.

You go modifying things and it's a different story,..especially with the 400.

 

Like 180mph.

 

If you are looking to purchase one go for the 400EX. I have owned both and the 400 is a much more awesome machine in my eyes. Go for a 05 + for reverse.

 

LOL thats funny
