not sure if it will save you any $, won't hurt to try - if you have any USAA account, don't need to have car insurance (I don't), they do their bikes through Progressive, basic liability for zx10r is 160.year
of course if you have a loan you need full coverage, personally if the bike is worth 4-5k I just save the $ and don't get it
