Unfortunately, as far as I know, there aren't any direct bolt on clear lenses for these bikes. If some were made specifically for these bikes they'd be VERY VERY expensive. I'd estimate setup costing around $10K. It'd take a LOT of lenses, "at a reasonable price", to even make their money back. I don't think we'll see these for a while, unless someone finds a set for another, high volume bike, that happens to fit right.
