if you put a nice set of graphics on them, they will snap. i got a black set and ride them blank. 25$ they are cheap but hold up enough. id rather have a nice set, but then again 25$ is to cheap. i got the kit where the number plates match the color of the bike.
I run an indoor mini supermoto series on my crf 50 and run the cheap amazon plastics. We go down quite often and run into each other. Have yet to snap anything yet. Only some crease marks where I can tell it has bent pretty far without breaking.
I just slapped a cheap set on the GF’s bike along with a BBR tall seat. One of the front mounts at the tank doesn’t line up (zap strap for now), and it’s touching the fuel valve and exhaust a tiny bit. But for $23 CAD shipped not bad.
