i have an 04 zx6 and i agree with a few others here...its the best all round 600 on the market so there's no need to brag or go on about it ! lol its an unspoken thing
i have ridden a 12 too....lots of power but just not my cup of tea...bit like a boat
go get a friggin alarm ! peace of mind it really is. I love my bike and would go to any extreme to minimise any chance of theft etc. Do it now to save hassles and regret later on
