I've got these things called KneeNecks they are a simple chap style wrap with velcro closures and go on wicked easy and work awesome. I started with a quilted set for use on my quad and later bought a set of leather ones which work great on the street. They also make denim and ballistic nylon versions. I had leather patches added to my quilted ones where the exhaust made contact.
You may think they are goofy but they do the job...
