I might add a second to the 2610. For less than $300 you can have the whole thing at your door, ready to go on your motorcycle. While $300 isn't cheap, you get a lot of GPS for that money.
I've been using various GPS units for a number of years, and I'm impressed with the 2610. This is an older, discontinued model, but I think as a new GPS user, you won't even notice.
The Quest mentioned above is a good choice, too. It's quite a bit smaller than the 2610 (Good or bad, depending on your perspective) and has an internal battery, so it can be used off the bike.
If you decide on something, let us know so we can direct you to all the parts necessary to get it set up and on your bike. Unfortunately, there's no 1-box GPS with everything included to set it up and get it on your bike ready to go.
