TX bike inspection questions '05 XR650L, '07 R1200GS 1st, does TX DOT require them? 2nd, what if I have aftermarket headlights installed (non-DOT)? 3rd, will I get by with my FMF Q4 pipe? 4th, its an annual inspection isn't it? 5th, my work has me travel for extensive periods, what if I am out of town for 6 months when my inspection sticker comes due. I hope to be changing residences to Dripping here in the near future, and I am making sure the bikes are going to pass.
