This is a pretty basic question but how does the 400 and 500 compare? I know the 400 is a 2 stroker so I assume its faster.

Thanks

 

In stock form they are both equal in power but the 500 has more lowend power.With a few mods the big differances start showing.The 500 turn into a torque monster with a pipe and proper clutching and the with a few other mods it is unbelievadle in the torque.
Now with a pipe,jetting,clutching,reeds,porting and a few more mods you can have a 400 4x4 that will run with the Banshees. But wont have the bottom end grunt of a 500.
I have had both and for tight rough trails the 500 is best.Now the 400 will shine on fast trails,hills and sand.
