I'm not entirely sure to be honest, that hadn't really occurred to me.
I think you're all missing the point, If motorcyclists cost more to insure than I'll happily pay more, but $800?, god that's about a 6th of what I was looking at paying for a bike. It seems the Gov is finding more and more ways to make revenue but the average wage stays the same. Even the simple pleasures in life like riding a bike on a sunny Sunday morning is denied the average Joe.
