Couldn't really find much information about tire fitment for Q3. I ran 160/60 dunlop Q3's on my DRZ on what I think was also a 4.25" rim with decent amount of chainrub but it was no big deal. Is it possible they're also fit my 07 SMR? Also, second question is where the hell can I find white rad. shrouds for my bike. I saw some other people asking same question years ago but the threads have just died.
