Progressive is the cheapest I've found. Even when I was insuring my old widow maker tl1000s it was less than $100 per year for above state min liability. The roadside assistance is ok but only covers a pretty small radius from home and the one time I used it, they left me waiting on the side of the road for 2 hours. Progressive said it was because the tow company was busy but when the driver showed up and I asked him, he said they had gotten the call over an hour ago and quoted progressive a price, then progressive called back an hour later and accepted it, so during that hour I was throwing pebbles at a squished squirrel carcass, they were calling all over town trying to find a better deal.
