Hmm, interesting. Never had anyone ask me about the weight, never had a tech ask about a GVWR sticker. They just look for the VIN tag, verify it, check brake light, headlight, horn and odometer and punch it into the computer. Never had them check blinkers either. (not a safety item)Haha that reminds me; I took my bike to a kwik kar oil change here in Anna and the tech asked me straight faced how much my bike weighed. I replied "off the top of my head i'm not sure, does it make a difference or can I make a guess?". I tried to google the GVWR before another tech found the tag for him. I'm guessing if your bike is too heavy its classified as something else?
Never had them ride any of my bikes nor have they asked about brakes.
