I'm paranoid about being a long way from home and losing my key. I prefer to leave my spare key at home (see- I'm also anxious about having "all my eggs in one basket"). If you're very lucky, you can buy a Honda blank with a chip, pay to have it cut then pay to have a Honda key the chip to your bike. The process can cost up to (and beyond) $200 and my experience on my previous bike was an expensive failure. Then I worked out a work-around which I wrote about here:
http://ozstoc.com/index.php?topic=6674.msg75933#msg75933With Ruby 2sday less than 500 km off turning 100K, I've left it a long time to take my own advice, but today I did it. I supplied an ebay-sourced blank to the locksmith and the whole process cost just over $100. I could have put the chip in the blank, but as a security item, I put it on a recoil cord to go on my belt. To start the bike I hold the chip against the key head and once the FI light goes out, I can let it retract and start the engine. That means I can leave the key in the ignition if I want to do a quick turn-around (e.g. an on-the-clock ride). The downside is, if you stall at the traffic lights, you have to grab the chip to accompany the key to restart.
I have a cut-down key for the fuel cap and panniers.
