Drz400sm Converted to Dirt trim?

Question for you guys, when putting dirt wheels onto a drz400sm, is it as simple as using the drz400S speedometer drive to get a correct speedo reading? and is it safe to ride off road with a 320mm rotor? thanks guys

I am unsure of the speedo drive but the rotor will be fine, just be aware that it will hang down further than a standard off-road rotor. So it can contact stuff more.

I do both (with stock 310mm rotor). Works fine for me.

i had no issues converting mine to offroad use. The front brake is a non issue.... its really nice just using one finger to get all the stopping power i need.
i replaced my dash so i could program in the wheel size (plus a tach and water temp)

It's safe as long as you don't ride over large rocks, roots, or ledges where the 320mm dia rotor comes in contact w/ them. I think a 240-260mm size rotor on a 21" wheel is designed that way for a reason when it comes to single track riding....to clear obstructions and not get damaged. I've warped my 240mm dia rotor 2-3 times so far from just falling down the wrong way. I can see a larger 320mm rotor being bent up quite easily riding technical offroad s/t.

thanks for the responses guys, so far in my research i see that when converting from an S to an SM people just change the speedo drive to an SM speedo drive and that works, so I assume the opposite is true as well?
