I was wondering if anyone knew what the offset is on stock 400ex rims because i want to get new ones but i want them to be the same size as the ones i got. I dont want to make the bike any wider than what it is now cuz i do alot of trail riding. thanks

 

Check the White Bros. catalog. It has lots of info on such things.

 

I'm not sure but I think there the same as the 300EX because I have 400EX tires on my 300 if that's any help !
