Muffler\exhaust protection

When I was a kid I fell off my bike and made a serious injury, I had to go to the hospital and get stitches. While waiting in the room came a teenage girl who was with her boyfriend, she burned her leg on the exhaust of his scooter. I always thought it was stupid that the bikes do not have at least a minimum protection.

This is what the engineers at Sym made for the Sym GTS 125 Evo...
